Question

Greg wants to find the median of a set of 9 data items. First,he ordered the items from least to greatest. What should he do next?

Answer 1

To find which term will represent the median, add 1 to the number of terms, then divide by 2 to determine the nth term that will be used.

$9 + 1 = 10$
$10 \div 2 = 5$

The median of the data set will be the 5th term in the ordered set.

Greg must add 1 to the number of items, then divide by 2.

Answer 2

After ordering the items from least to greatest, he should find the term in them middle. That term would be the median.


hope this helps
