Averages On A Calculator
Muhtasari
Finding averages by hand is fine for a few values, but real data sets can have hundreds of entries. A graphic display calculator handles them in seconds: type the data into a list, run the one-variable statistics, and read off the mean, median and quartiles instantly. It even handles grouped data using frequencies.
In this lesson you will learn the general calculator method, described in words so it works on any model, for finding the mean, median and quartiles of discrete data, and the mean of grouped data. This frees you to focus on interpreting the results rather than grinding through arithmetic.
Malengo
- Use a graphic display calculator to calculate: 1 mean, median and quartiles for discrete data 2 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,
