Measure of Central Tendency (Mean of Ungrouped and Grouped Data)

A branch of applied mathematics that deals with the collection, organization or presentation, analysis and interpretation of data.

• Statistics

• Census

• Population

• Survey

It is a summary measure that attempts to describe a whole set of data with a single value that represents the middle or center of its distribution

• Statistics

• Measure of Central Tendency

• Measure of Variability

• Probability

It is the sum of all the values of each observation in a data set divided by the number of observations.

• sample

• mean

• median

• mode

The mean is also known as the _______.

• average

• middle score

• first score

• last score

The mean of ungrouped data can be computed by dividing the __________.

• First score by the total number of values

• Middle score by the total number of values

• Sum of all the measurements or the values by the total number of measurements

• Sum of all the measurements or the values by 10
