Measures of Central Tendency

Last Wednesday, we talked about data and its uses. Here are the 3 definitions that we learned about.

  1. Mean: The mean of a set of data is the sum of the data divided by the number of pieces of data.
  2. Median: The median is the number in the middle when the data are arranged in order from smallest to largest. When there are 2 middle numbers, the median is their mean.
  3. Mode: The mode of a set of data is the number or item that appears most often.

The most common mistake students make is to NOT PUT THE DATA IN ORDER! Here is a link with examples!
