Answer:

Explanation:

First step: Order from least to greatest.

4,5,5,8,9,10,10,10,12,14,15,16,16,18,19,21

Second: If the we had an odd amount of data, the median would just be the middle number. Since we have even amount of data, the median will be average of the 2 middles.

You have 16 data members here. The middle is going to be at the 16/2 th term and the [(16/2)+1 th] term. So in other words we need to average the 8th and 9th term here to find the median. So let's count to the 8th and then then the 9th to figure out what numbers these actually are.

8th term=10 and 9th term= 12 so the average of these are (10+12)/2=22/2=11.

The median is 11.

Why is it useful for historians to craft historical narratives

REY [17]

Historians need to make a picture of history so people can understand what happened. They use fossils and artifacts to make a picture of what that period of time was like. They interpret objects, and read scripts from that time to trust understand what was going on. This way, people can understand and learn from the past. We do not have to make history repeat itself.
