Begin your journey by learning why and how to summarize your data using statistics such as the mean, median, and mode. While working with a variety of datasets ranging from Amazon revenue to U.S Presidential ratings, you'll learn about the differences between each of these fundamental statistics and most importantly, when to use each.  

Welcome to the course!

Getting To Know Your Data

Data visualization is one of the most important parts of any data science workflow. It leads to a deeper understanding of your dataset which in turn allows you to more effectively communicate results to stakeholders. In this chapter, you'll learn how to visualize your data in Google Sheets using statistical plots such as the histogram, scatter plot, and bar plot.

Visualizing Distributions

Visualizing customer longevity

Visualizing customer donations

Is the data "normally" distributed?

Visualizing Correlations

Correlation between price and quantity sold

Correlation between seller rating and closing price

Adding a trend line

Bar charts

Bar chart of competitive counts

Visualizing categories

Statistical Data Visualization

This chapter introduces you to statistical hypothesis testing. You'll learn how to construct a hypothesis, test it using different statistical tests, and properly interpret the results.
