The following were Janelle’s 8 quiz scores:

22 24 24 26 27 27 29 30

Janelle thought her median was 26 Jimmy thought her median was 26.5 And June thought her median was 27

Who was right, and why?

The following were Janelle’s 8 quiz scores:

22 24 24 26 27 27 29 30

The median splits the data exactly in half. If you put four(4) numbers on

each side of the median, it would be in-between 26 and 27. Jimmy was right,

the median is 26.5

Final Jeopardy

Jen wants to average 92% on her 5 math tests. After taking 4 tests, her average is 90%. What does she need to score on her 5th test so that she averages 92% overall?


Final Jeopardy Answer


To average 90% on 4 tests means the total number of points accumulated is 90 x 4 or 360 points.

To average 92% on 5 tests means the total number of points accumulated is 92 x 5 or 460 points.

Since 460-360 = 100, Jen must get 100% or 100 points on the 5th test to average 92%.
