1 Mean, Median, Mode and Standard Deviation (Section 11-1)

2 Statistics: Numerical values used to summarize and compare sets of data
Measure of central tendency: A number used to represent the center or middle of a set of data values.

3 Example1 Below are the intervals (in minutes) between eruptions of the Old Faithful geyser in Yellowstone National Park. Calculate the mean, median, and mode for the dataset:

5 Measure of dispersion: A statistic that tells you how dispersed, or spread out, data values are
Range: The difference between the greatest and least data values.

6

7 Standard deviation: A measure that describes the typical difference (or deviation) between a data value and the mean Variance: The average (mean) of the squared differences from the Mean
