Averages On A Calculator
Gbogbo ọrọ náà
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.
