Measures of Central TendencyMeasures of Central Tendency

Median ValueThe Median is the "middle number" 

(in a sorted list of numbers).

To find the Median, place the numbers in value order and find the middle

number.

MeanThe mean is the average of the

numbers.It is easy to calculate: add up all the numbers, then divide by how many numbers there are.

ModeTo find the mode, or modal value, first put the numbers in order, then count how many of each number. A number that appears most often is the mode.If all numbers appear an equal amount then there is no mode.

Range The Range is the difference between the lowest and highest values. To find it subtract the Largest #- smallest #

Box and Whisker PlotsBox and Whisker Plots

Box and whisker plot is a way of displaying data.

It has 5 parts.

Lower extreme (lowest number in the data set)

Lower quartile (1st quartile) (median of the “lower” numbers)

Median (2nd quartile) (middle number of the data set)

Upper quartile (3rd quartile) median of the “upper” numbers)

Upper extreme (highest number in the data set)
