Measures of Central Tendency | Mean, Median, & Mode
The three important Measures of Central Tendency are Mean, Median, and Mode. Mean is equal to the sum of all the values divided by the total number of values.
Measures of Central Tendency | Mode
Measures of Central Tendency Mode. Mode is the most frequently occurring value (or class) in data. Mode can be used as the measure of central tendency.
