Data Distribution with Graphs

• Curve shows a data set that is normally distributed

• Most of the data is located near the middle (mean) of the distribution

• Mode is larger than mean or median

• Distribution is symmetrical

• Mode is higher (larger) than mean or median

• Mean is higher (larger) than mode

• Median is located between mean and mode

• Median is higher (larger) than mode

• Both curves show normal distributions

• Mean, median, and mode of curve A are ALL approximately 25

• Mode of curve A is higher (larger) than mode of curve B because the curve is taller

• Curve B has a higher mean because the curve is positioned further right on the x-axis

• MEAN

• MEDIAN

• MODE

• Cannot be determined without numbers on x-axis

• Curve A

• Curve B

• Curve C

• All 3 distribution curves will have the same mode (they are all same height)

• Curve A

• Curve B

• Curve C

• Both curves A and C

Which choice below is NOT true about bar graphs and histograms?

• Bar graphs have gaps between bars...Histograms do not

• Bar graphs have categories on the x-axis...Histograms have quantities

• Distribution curves can be created from bar graphs or histograms

• Every element in a bar graph has its own bar...this is not true with histograms

What type of distribution curve is represented by a symmetric "bell-shaped" curve?

• Right/Positive skewed distribution

• Left/Negative skewed distribution

• Uniform distribution

• Normal distribution

• MEAN

• MEDIAN

• MODE

• Cannot be determined because x-axis is not labeled
