  1. FREQUENCY TABLES, LINE PLOTS, & HISTOGRAMS

  2. TERMS Frequency  number of times that something happens **The key here is that frequency is always about the NUMBER of times Frequency table  a table that shows the frequencies of items

  3. EXAMPLE 1 A number cube was rolled 20 times. The results were: Make a frequency table of this data.

  4. EXAMPLE 1

  5. 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.

  6. X X X X X X X X X X X X X X X X X X X X 1 2 3 4 5 6

  7. HISTOGRAM A graph that shows the frequencies of the data **Looks like a bar graph.

  8. EXAMPLE 2 The number incorrect on the latest quiz in Mr. Marvel’s algebra class • 1 10 5 2 2 1 1 9 1 7 0 2 3 3 1 0 4 8 4

  9. EXAMPLE 2 • 1 10 5 2 2 1 1 9 1 • 0 2 3 3 1 0 4 8 4 • Decide on an interval size (starts with 0 goes to 10) Interval size: 2
