Objective: Create and interpret frequency tables and line plots.
Data – pg. 72 - information, often given in the form of numbers or facts.
Frequency Table – pg. 72 - a table that displays the number of times each item or category occurs in a data set.
Line Plot – pg. 73 - a number line diagram that uses X marks to show the frequencies of items or categories being tallied.
What is your favorite color?
To find out which color is chosen most often, we can make a frequency table.
When the items or categories being tallied are numbers, a line plot can be used to visually display the data. A line plot uses X marks above a number line to show the frequencies.
The X marks above the number line show the frequencies.
The Number Line shows the number of books read.
Number of Books Read
How many siblings (brothers and sisters) do you have?
Let’s make a frequency chart for the class.
