5.3 Frequency Tables and Line Plots (p.114-117)

I. Frequency refers to how many times something occurs or happens

• Cumulative Frequency: the running total of the frequencies - add each part together as you go down the column to show a "running total" with each item
  
• Relative Frequency: the frequency of the category divided by the sum of the frequencies (often given as a percentage of the total or shown in a graph for comparison)

I. Ways to show data: Frequency Tables and Line Plots

• A Frequency Table lists the items being recorded and tells how many times each item occurs. Sometimes tally marks are used to count the frequency. Below are two seperate examples.


• A line plot shows the frequency of data on a number line by using an "x" or other symbol
