Express mean, median, and mode

In this lesson you will learn to express mean, median and mode as a single number by pulling data from a line plot.

Distinguish between measure of center and measure of variance

In this lesson you will learn the difference between measure of center and measure of variance by using a line plot and a number line to find the median and variance of a set of data.

Solve a real-world problem involving measures of center and variance

In this lesson you will learn to solve a real world problem involving measures of center and measures of variance by using a standard algorithm.

Identify clusters, peaks and gaps in a dot plot

In this lesson you will learn how to identify clusters, peaks and gaps and their relationship to the data by examining the distribution on a dot plot.

Summarize the center of data with a single number using mean, median,…

In this lesson you will learn how to summarize the center of data with a single number by examining the mean, median, and mode.

Summarize the spread of data using range and mean absolute deviation

In this lesson you will learn how to summarize the spread of data with a single number by calculating and examining the range and mean absolute deviation of the data.
