Measures of Central Tendency
Find a Middle Ground
The measures of central tendency- mean, median, and mode- are quite simply three different ways of looking at the way numbers behave towards the middle of a data set. Knowing the behavior at the center can help us to better understand data.
STEP 1: WATCH THE VIRTUAL CLASS VIDEO AND TAKE NOTES
Make sure to note the following:
There are three measures of central tendency that you need to know for the GED® test: mean, median, and mode.
Mean: Also known as the average is the number you would get if all the data was shared equally. Simply total the data, then divide by the number of items in the data set*
Median: The median is the centermost number in an ordered data set*
Mode: The most commonly occurring item in a data set.
*See the GED® formula sheet for more information
