What is mean in the measurement of central tendency of ungrouped data?

Sagot :

Mean is the most commonly used measurement of central tendency. It is used a set of data where the measures cluster or concentrate at a point. As the measures cluster around each other, a single value appears to represent distinctively the typical value.

This is according to my book so 100% the definition is gradually correct...

Hope it Helps =)
