Data Literacy: Making Better Business Decisions With Data

, I help startups gracefully scale human systems

You want to know if that social media strategy is working? Look at the data. You want to predict customer behavior? Look at the data. After this course you will be able to use the data your company collects to ask and answer important business questions.

The ability to analyze data is a sought after skill. I should know, I got my first job working for American Express when I was 18 because I had the skills I'm teaching in this class. Decisions are made based on data more and more. If you want to be a decision maker, or have the knowledge to incluence decision makers, you need to know how to analyze data.

This four class series will turn even the most math phobic person into a stats nerd. Data is the way of the future. Even if you don’t plan to become a statistician (though this would be a great first course if you do – trust me, I’m awesome at teaching), you should learn to be data literate to sift through the nonsense and know a charlatan when you see one.

We will also cover the basics of R, a very powerful and versatile open source tool (download it for free). Please come with R and RStudio loaded on your laptop if you’d like to follow along. Don’t worry if you don’t have a laptop – you can watch in class and I’ll send you the command lines to look over at home on your Commodore 64 (though I’m not guaranteeing R is Commodore compatible).

Topics we will cover include:

Hypothesis testing
Statistical significance
Statistical power
t-tests
ANOVA
Correlation
Regression

Prerequisites
Prerequisites: Don’t let your fear of math stop you from being great at stats! All of the math you need for this course you learned by the 10th grade (if you were slow – 8th grade for the rest of us).

    Ever wonder if an apple is larger than a watermelon (relative to other apples and watermelons, of course)? First, ask yourself why you considered such an odd thing in the first place. Then, find a z-score for both pieces of fruit. This class will teach you how.

    This course covers the basics of practical statistics and R, a free program that will enable you to explore your data. You’ll learn to ask the right questions and determine what data you need to make informed decisions. We’ll cover the basic vocabulary and concepts needed to analyze data and think like a statistician, how to summarize large data sets so non-savants can make sense of them, and how to compare data from different sources in a way that is meaningful. (For you apple-to-watermelon comparison enthusiasts, yes, that means you will finally be able to figure that mystery out.)

  • Testing Hypotheses

    Though they lie about it, your parents don’t love you and your sister equally. In this class you’ll learn to compare two means (say, a running measure of your mom’s love for you and some unnamed sibling) using t-tests. Just hope you don’t find out they love Fido best.

    After taking this course you’ll be able to use data to make informed decisions about your business by stating and testing formal hypotheses. You’ll learn how increasing sample size reduces error (and makes significance tests irrelevant at a certain point) and how to use t-tests to compare means.

    Want to run A/B tests to see which page leads to more revenue? Just like your parents’ love for you and your sister, we can compare the two. They don’t love you the same and the internet has a favorite too.

    Have you ever noticed that 90 degree weather isn't so bad when the humidity is low, but 85 is awful with 80% humidity? How about 80% humidity but only 60 degrees out? Not so bad, right? Temperature and humidity interact to create weather conditions, just like the variables you are interested in for your new social media push.

    Okay, that weather example was stupid (I’m teaching stats, not copywriting). What if you want to know if a Tweet (does that take capitalization?) is more likely to be re-Tweeted if it has a link, a picture, or no media attached? What if you also want to know if time of day has an effect on the media you attach (are people more likely to re-Tweet a link earlier in the day and a video later in the day)? This class covers the statistics used to test such interaction effects.

    Palm readers are lame. Statisticians are sexy. Billy Beane (of Money Ball fame) turned a crap team into a winner using statistics, not voodoo. You should do the same. Make your business awesome with regression. Come to my class and I’ll teach you how to make predictions with data. Seriously.

    This class will teach you how to use correlation and regression to make predictions using the data you already have.
