1 Section 12.2 Frequency Tables, Line Plots and Histograms
Algebra Concepts Section 12.2 Frequency Tables, Line Plots and Histograms

2 Frequency table-lists each data item with the number of times it occurs

3 Line plot-displays x marks above each value on a number line.

4 Histogram-show the frequencies of data as a graph

5 Histograms Label axes Determine intervals (these can be different)
Mark Intervals (must be evenly spaced)

6 Determine the intervals
Find the range. Choose the number of bars you want Divide the range by this number

7 How many miles from school to your house?
Collect data Decide on intervals Make a frequency table Make the graph
