The mode is the value that appears most frequently in the data set, which can be found by looking for the highest frequency in the table.

Front

Back

A frequency table lists values and their counts, while a dot plot visually represents data with dots.

Front

What does it mean if a size has no dots in a dot plot?

Back

It means that no data points were recorded for that size.

How can you compare two sizes using a dot plot?

Back

You can compare two sizes by counting the dots above each size and seeing which has more.
