About This Class

A great introduction to SPSS. What do you see and what can you do with it?

1. Opening SPSS and looking around in Data View : Hello. This is Storm Evora, your statistics teacher, And I'm skilled to explain you things about FDA. This How can you do all kind of statistical regressions within SPS? That's how can do, uh, compare different groups. How can you see if difference are really different for me, Torre? And if you're still a student, I'm really glad if I can help you finish your exam. So what we gonna do now is really easy. Open, Spfl. That's where we're going to start with over here, you see, like, different kind of fouls on. Most important thing is, if you see the logo like you see over here, it's SPS logo. So, like all other programs on the computer, just double click it. And what you see over here is a FDA that's far. One second. I just had to do this. My excuse for it. What you see over here is all different kind off variables to get A with persons person. One he had probably zero exams. Did not met one nice person. He did every minutes of sports standpoint. Nine. His day was one wanting to eat a burger. If people on 05 countries one great for his first test was eighth grade for second test then, and that's what you can see over you. First of all, day is one or zero. You can see it over here. This is the information for person to information from person. Three information from person, for If you just want to fill in data by hand, it's quite easy. You just go to person 221. You got your inquiry, and you just like ask people how much exams that you had to make too many nights. People that human, maybe six. You just fill in the six. How many sports did you do it every time, and it's a nice feeling. 10. But now you got a problem. Which day is it today? Are you know it yourself already, But for example, it's Friday and you see a one and a zero. What is the one? What is is there if it's fighting, so there's a little bit in over here. You see the biddle want to A You have to present and assume if you present, you see that the ones convert into Monday till Friday and the weekend equals zero. So if it's Friday. Today you see like you have to feeling like it's a monitor Friday so you can feel in one year and assume we click 81 again. We see it's Monday to Friday. I would remove these data again. You can just right mouse click on the number you can say clear. A notable person is gone from your data set. There's a lot of burdens. Moreover, you're not gonna explain them now. You will see them later. Sometimes they find the fine burden is nice. But, uh, for example, if I know I'm interested in person movement, seven nights, people just around them, I can click find first of breath. This thing I can say. Find a seven find next and hear my friend Burt Person, 87. He met seven nights people. So let's get the nice You can find things next to it. You can click with the right small burden and you sort ascending or sort decent. But what's out? A little bit of it, because if you press sort ascending or descending after watch, you will, Data said. James cannot put it back, so the way to put it back to make it more easy. There's quite some steps, so please pay good attention. First I press here, Right mouse button, I say inter variable. That's the way to insert available at a certain moment. I changed the name by double clicking on it and you get a new menu. And over here I can put in the name and I will white here case remember or like mate means like person number. Now we go to transform computer available and in this menu, right up exactly the same road as I just put down case number and I press down here Dollar case number. Really, it's important this this thing. So why did down somewhat case him or like, the dollar casing Then I press okay. Changes Xing excess invariable. Okay. And what you see over it's just coming up. Actually, you don't use this thing. But now the nice thing is And if I start ascending on metalized person, see 1st 112345 Now I can put a data set like how itwas by just pressing the case number and ascending on this one again is a little take within SPS. But sometimes this is really, really important especially even in later states. You have to add data to your data set, especially variables, because otherwise you cannot find back with variable with which normally wife, too, who feeling for which person and now you can easily find them back. But president, right mouse button sort ascending, descending. But of course, if you need to find in them, you can always use them. Find it, button. Let's go to the terrible view. And I will explain a little bit more about the terrible view in the next video. So please keep hanging on. Thanks for watching the first Espy s s video. Really looking forward to explain you more about business, especially the variable view in the next video. 2. Opening SPSS and looking around in Variable View: Hello. This is Stone for Borda, your statistics teacher. And in this video I'm going to explain something about a variable view in FBS s. So let's have a quick look over here. You see the date of you check my last video and if you click here, you get a variable view on what you can see over. You can feel in all the information which belongs, for example, to the variable day like you see over here. And we practice the last time. If you have the one it means like monitor Friday and zero is the weekend. This kind of things you can do inside the variable view. So let's get into it. If you have available, you can see he is the name on. See also the label, for example. He is He met a nice person and he c n off exams and of examples quite short and ideas to keep the the names quite short. Because you see them over here and you want to see directly What is what? So end of exams will be actually remember exams that day? It's quite long. One, the label. But the label can be long. One and you can shorten it into enough exempts. And if you do your analysis and SPS s, it will give the name no more exams on the day inside off enough exams you can directly hands in your off. Present your materials, your alcohol. Really nice. So actually, if you have these data said, you should do with four everything. Everything. You should give a label they today, all week wanting to eat a burger. It's like No. 90 with his times below, so I can make it here the same without his tax below really important Internet name sealed . If I put the same on here with wanting to eat a burger without the straps below, I get the message. Variable named contains an illegal character. And that, of course you don't want say you cannot put it in. You cannot put the space inside the name, and you cannot put like a normal strap. You can put the lowest crap like this, but not the normal time. And get also that's illegal character. Next thing to look at will be, let's check. This one is an interesting one. You see the county, and there's four different kind of countries. So I compress here is like 123 or four and if you present fell, use this very you compress like on this little button, it starts to appear, and as soon at present here, you get into the value labels menu specifically for this variable. Of course, if I click, he only move. I can remove one. Now it's gone. If I want to add it back again, I can press to label. And now and it's back. Of course, I can also add a new one. For example, five equals the United States at five. This United States. So if I go to date of you and I would change this 1st 1 into a five, press this button, I see a The 1st 1 is the United States, but actually it was quick. So I selected Creek again. He can just select no, see the five ones which were there to fill them in easier. You can de select Anneke feeling the numbers easier. Next thing is the type of edible off course. If you look to a variable that country, it looks like it's a string variable because you can press characters never put available like country as a strength available into Espy's S on Lee Boots only used for staying variables like extra information like I use a deer some questions or, like some hints for yourself. Or if you have a open question, it could be a question like, Which country are you from Where, then you will know, do analysis with it just as a quality, Take qualitative question, and you can, like put in oak countries off the world, which are really a lot. But as long, if that's not possible. This just four or five, maybe even 10 different countries used it, though you want built in and give them name like this and always keep the type on numerous . If you don't do it, you cannot do a lot off analysis. Next thing is the with what has to do. Actually, when the type of string, for example, if I cared a new variable name on put the with four over a year in the name and I want my name is Danny or, for example, I cannot feel in the name Daniel because it's more than four letters so pre firmly, if you have a name just this kind of able Just keep this number high. You can only keep it till 40. So preferably if it's a staying variable Something, um, give you with on 40. But like I said before s possesses the poem for numeric variables, not for string ones, so that you don't have to use it with variable decimals is how maney that's most. You can see, uh, for example, wanting to be the burgers. He all kind off like easy 3.5 people for 63.53 point 51 And if I press here, I don't want any decimals for it would be this variable zero. I see the various like this. It doesn't matter. I mean that all the decimals are gone like an analysis. They will still come back. But they were just hidden for view. Sometimes it's nice to feel not too much decimals. And sometimes there's variables like this case in, um, it's just 123456789 10. Of course, you don't need the decimals because they're always here. Label. I explained to you values next one is missing. Sometimes if there is a very was missing. For example, this one I compressed lead and now it possessed knows this is nothing and it will not do anything within the data set. But a lot of people prefer not to. Hey moves something but to put the number minus 99 off minus 999 in a data set and which means it's a missing value. But SPS doesn't notice, say, because for some cases, you can have value off. Mine is mine on the minus 999. So what you need to do is press in this case, missing off the variable great second exam. And over here I press discreet missing values and this number and now this number. You don't see anything here happening now at this time, but it is reduce it as a missing value. So now it's the same as just when it would be would have bean deleted. That's about missing values off here columns is not important at all. Actually, I just searched it out. What it needs, it means like here. Column of case number is now 12 never enlarges to 15. You see what happens just becomes a large field. But nowadays would be. It's like something from the past. Nowadays you can just like make it small again and you see directly that columns changed too. Align quite common. Also used in verge of some problems. You can align to the right to the left measurement level for a lot of analysis. In SPS, you don't really need to put its but please put it. It's nice. Yeah, so you can put it, like as a scale or, you know, no me? No. And if you put it right directly, it makes your analysis more easy. So let's do it. Country is typical. No, me, no. Check my video about nominal orginal and scale to see what is what. But greats, they're not know me. No, but their skill. So I changed them. You see, he directly to see year becomes the scale sign. And if I click on so analysis you see directly, Which one asked, which ones are skill, which wants a nominal, and it makes your data more clear? At last you see a role. It's some of the latest version, and until now it's not used yet. Almost not so if you want more about more information about this you can find online or ask me if you really need to use it. I will make a video, but for now I will skip it. A lot of information. Track to change all the stinks yourself with your own data or this data fell and see what happens. Thank you so much for watching this video. 3. What is Syntax and how to use it?: Hello. This is Stone from Florida, your statistics teacher and this video, and going to explain something about syntax on what it is. Syntax is something from a long time ago. Like all the computers used to work only with syntax, you had to program things into into the computer and then, by difficult commands the computer. Start doing something. If you make like one little mistake in it, it computer crashes and doesn't do anything. So in this way, syntax sounds horrible, but wouldn't este that it has certainly its advantages. And it is not that difficult to use because you can. Jenna let SPS has generated Syntex for you, which has some big advantages. Imagine having created the data set. Data set is old. Oh, good, he's think. At least you do 50 different analysis, and afterwards you notice that one off the numbers you filled in into the data said was warm. This means that all your 50 analysis you have run, you have to warn them again. So that's a lot of work. If you made a syntax before you can just press a button and the 50 analysis will be real and automatically so that's a big advantage next to it. It gives a documentation on a lot of times students just needed for their professors. And then we have to generate the syntax. So let's go to how to generate syntax just for something really easy opening a foul, Everything in s possess has a saint docks at that's to it. So if you want to open a foul, go to this big open button and I click on a foul on instead of clicking open, then it would open it directly. I click on based the based means put it into the same talks I present to paste and you see directly that not a file itself is opened. But the ESPYs s statistics Syntax editor. So the fouls another open jet like you can see. And if you want to open it, I have to select this piece off. Same talks. I just selective and then passed is big play button. I pressed the play button you see magically to foul opens. Great. No, something more about syntax. There's a little bit more advanced because I will do some analysis here, which I will explain in the later videos. But I wanted to put attention to syntax first, because for a lot of people it's important. So if you don't know the analysis I'm doing neglect is just about that. Basing the syntax if it wants from descriptive like from number off exams, press of one button. Sorry, number of exams. I want defending. Just click on some things on our press, Not okay. Then I would get output. But for the past based, nothing is done. And now I go to one simple t test. Just feeling some information you can just if you practice this feeling some information yourself, better look to next videos and practice with the next videos. Yeah, past based again. What you will see over here if I go to Syntax editor is it was the first piece of syntax for opening the foul. Here was the second syntax for descriptive off a variable as last varsity test. What I can do over here is because at the end you get a lot of Centex if you If you want to remember for what things, things were important. You can make little comments in it, but if you want to make little comments, remember to start to commend with a star If you start typing and I have to enter comment with dot And now this is a safe comment on here. Of course, you can always based things within the san text. This will be the most awesome syntax ever. What you see is that Estes has helps you. It creates this little great grayish color with me is like I don't use this same truck spot . Now I can run the both things together just by selecting all the text. My commence will be this guarded because it has a star in the phones on adult at the end And here I press play And now you see over here, that's first. The descriptive analysis is one and afterwards the T test. So let's recap this video. Why? To you syntax first since the documentation if you teach, you asked for it. You can always give him like I did this. This this analysis and you can see my results. But I also have two syntax if you want to do it by yourself again. Secondly, if there was some mystic in your data, you can correct your data and relearn the syntax Just by selecting the part again and pressing the play button might not work because you already run it. Used to copy paste comments, control C Control V or with the right mouse button and created syntax again and then press on that piece play. Thank you so much for watching this video.
