Sets of Data

​

Set of data

A list of anything

Could be a list of exam scores from an exam

Recap on median and range

Median: The middle number of a set of data

1,2,3,4,5,6,7

The median of the set of data above is 4 since it is in the middle

Range: Take the highest number and subtract it from the smallest.

1,2,3,4,5,6,7

7 - 1 = 6

So, the range is 6

Mode

The number that occurs the most offten within the set of data. So in this example the mode was 3.
