1. Histograms Hours slept Frequency 1 – 2.92 3 – 4.95 5 – 6.910 7 – 8.913 9 – 10.92

2. Titled Vertical Axis Shows Frequencies Be sure to clearly label axes with quantity measured and units (when appropriate) Starts at 0. Graphs that cut off some values can be misleading

3. Hours slept 1 – 2.9 3 – 4.9 5 – 6.9 7 – 8.9 9 – 10.9 Lower class limits used as class boundary 5.0 would be included in this bar

4. Relative Frequency Histogram

5. Bar Graph (alternate form of a histogram)

6. Frequency Polygon

7. Ogive (Cumulative Frequency Polygon)

8. Stem and Leaf Plot (variant of histogram that shows all data) Stem (ones)Leaves (tenths) 12 29 315 4468 503347 637789 701224558 812256 93 101 Data: 1.2, 2.9, 3.1, 3.5, 4.1, 4.6, 4.8, 5.0, 5.3, 5.3, 5.4, 5.7, 6.3, 6.7, 6.7, 6.8, 6.9, 7.0, 7.1, 7.2, 7.2, 7.4, 7.5, 7.5, 7.8, 8.1, 8.2, 8.2, 8.5, 8.6, 9.3, 10.1

9. Pie Charts

10. Pareto Chart For Qualitative data Can also be used for Nominal level data For Ordinal level data, you would want your horizontal axis in “order” Data groups are arranged in order of decreasing size

11. Scatterplot Pairs each value from data set to a value from a second data set to create points.
