# Data distributions

High school statistics,

Data makes more sense when we graph it and summarize it with numbers.

This course contains 5 segments:

Displays of distributions

A picture says a thousand words. A well-made data display can show data in a way that everyone understands. In this tutorial we'll learn how to construct and describe some common displays of data.

Summarizing center of distributions (central tendency)

How long does a typical person spend on a phone each week? Is it different for younger people? In this tutorial we'll use measures of center like mean and median to summarize and compare sets of data.

Individual results will vary. Measuring spread in distributions helps us to describe how much variability there is in a set of data. In this tutorial we'll use range, interquartile range, and standard deviation to talk about the spread in a data set.

Box and whisker plots

Whether we're looking at scientific data or stock price charts, box-and-whisker plots can show up in life. This tutorial covers what they are, how to read them and how to construct them.

Comparing distributions

Do people live longer in different parts of the world? In this tutorial we’ll compare the center and spread of distributions to see what conclusions we can make.
