Learning Goal: I’m working on a statistics writing question and need a reference to help me learn.


The most common measures of central tendency used in statistical analysis are:

Mean: The arithmetic mean is the sum of all values in a data set divided by the number of values. It is a widely used measure of central tendency and is sensitive to outliers.

Median: The median is the middle value in a sorted data set. Half the values in the data set are above the median and half are below it. It is a robust measure of central tendency that is less sensitive to outliers than the mean.

Mode: The mode is the most frequent value in a data set. It is useful for nominal and ordinal data but may not be unique or may not exist for some data sets.

Each of these measures has its strengths and limitations, and the choice of which to use depends on the nature of the data and the research question being addressed.
