       Measure of Central Tendency       Measures of Dispersion
       • Mode- the number that appears   • Range- the difference between the 
        most often in a data set          greatest and least values
                                         • Quartile- a value that separates a 
       • Mean- the sum of all numbers     finite data set into four equal parts
        divided by the amount of 
        numbers (average)
                                         • Interquartile Range- the difference 
                                          between the third and first quartiles
       • Median- the middle of a set of 
        ordered data                     • Outlier- a data value that is much 
                                          greater or much less than the other 
                                          values in the set
         Find the mean, median, mode, 
         outlier, and range of the data set
