Back

The mean is the average of all data points, while the median is the middle value.

How can you identify clusters in a data-dot plot?

Back

Clusters are identified by groups of dots that are close together on the number line.

Front

What does it mean if a data-dot plot is skewed?

Back

A skewed plot indicates that the data is not symmetrically distributed, with more values on one side.

Front

How do you calculate the mode of a data set?
