Let's explore different kinds of data.

Let's look more closely at data and the questions they can help to answer.

Let’s represent data with dot plots and bar graphs.

Let's investigate what dot plots and bar graphs can tell us.

Let's use dot plots to describe distributions and answer questions.

Let's explore how histograms represent data sets. 

Let's draw histograms and use them to answer questions.

Let's describe distributions displayed in histograms.

Let’s explore the mean of a data set and what it tells us.

Let's look at another way to understand the mean of a data set.

Let's study distances between data points and the mean and see what they tell us. 

Let's use mean and MAD to describe and compare distributions.

Let's explore the median of a data set and what it tells us.

Let's compare the mean and median of data sets.

Let's look at other measures for describing distributions.

Let's explore how box plots can help us summarize distributions.

Let's use box plots to make comparisons. 

Let's compare data sets using visual displays.
