TERMS Data  information Frequency  number of times that something happens Frequency table  a table that lists the number of times each item occurs in a data set

Making a Frequency Table A number cube was rolled 20 times. The results were: Make a frequency table of this data. 2 6 5 3 4 1

LINE PLOT To make a line plot: Draw a number line that includes all the values (in example 1 this was 1,2,3,4,5,6) 2. Place an “X” above each number to indicate the number of times it occurs.
