The video covers creating line plots, organizing data on a number line, and comparing dot plots with frequency tables. It also discusses practical applications of dot plots and their importance in data analysis.

What is the primary purpose of a dot plot?

• To organize data in a chronological order

• A percentage

• A category

• A pair of values

How can you check if your dot plot is accurate?

• By counting the number of values
