85 73
72 75
72 71
how much greater is this weeks median temperature than last weeks median temperature?
o 2 degrees
o 3 degrees
o 4 degrees
o 5 degrees

Explanation:

Step1: Arrange last - week's data in ascending order

$51,62,66,68,72,72,85$
Since there are 7 data - points, the median is the 4th value. So, last week's median is 68.

Step2: Arrange this - week's data in ascending order

$65,71,73,73,73,74,75$
Since there are 7 data - points, the median is the 4th value. So, this week's median is 73.

Step3: Calculate the difference

$73−68 = 5$

Answer:

5 degrees
