Mean, Mode, Median And Range From Discrete Data
Muhtasari
A single number can summarize a whole data set. The mean, mode and median each pick out a typical value in a different way, while the range measures how spread out the data is. Together they are the everyday language of statistics.
In this lesson you will calculate the mean, mode, median and range from discrete data, and understand what each one tells you and when each is the most useful.
Malengo
- Calculate the mean, mode, median and range from discrete data, and (Extended) the modal class and estimated mean for grouped data.

Measures of the Center of the Data
The "center" of a data set is also a way of describing location. The two most widely used measures of the "center" of the data are the mean (average) and the median . To calculate the mean weight of 50 people, add the 50 weights together and divide by 50. To find the median weight of the 50 people,
