What is a Measure of Central Tendency?
A measure of central tendencyThe Measures and definitions for central tendency allow you ... Learn More... is a single value that describes the way in which a set of data cluster around a central value. In other words, it is a way to describe the center of a data set.
The three main measures of central tendency are:
Mode of the Distribution

When to use Mode as a Measure of Central Tendency?
The mode is useful when the set of data:
- has more than one segment (or multi modal)
- is badly skewed, or
- it is necessary to eliminate the effect of extreme values.
Examples of variables with bimodal distributions:

In fishery science multimodal length distributions reflect the different year classes and can thus be used for age distribution- and growth estimates of the fish population. Sediments are usually distributed in a bimodal fashion. Bimodal distributions are also seen in traffic analysis, where traffic peaks in during the AM rush hour and then again in the PM rush hour.
