Dot plot and frequency tables

A dot plot is a simple way to display data using dots above a number line, where each dot represents one data point.

A frequency table is a table that displays the number of times each value occurs in a data set.

To read a dot plot, count the number of dots above each value on the number line to determine how many times each value occurs.

Each dot in a dot plot represents one occurrence of a data point.

To create a frequency table from a dot plot, count the number of dots for each value and list the values with their corresponding counts.

The purpose of a frequency table is to organize data to make it easier to understand and analyze.

To find the total number of data points, add all the frequencies (counts) together.

Dot plots and frequency tables both display data, but dot plots use visual dots while frequency tables use numbers to show counts.

If a dot plot has more dots above a certain value, it means that value occurs more frequently in the data set.

To determine the most popular choice, look for the highest frequency (count) in the table.
