A statistics teacher was reading through a summary of his electric usage for the previous year. Typical high temperatures for each month were included in the summary and the teacher became curious about the distribution of those temperatures. Here are the data (measured in degrees Fahrenheit). 22, 31, 64, 64, 42, 81, 79, 71, 79, 79, 52, 38

a. Find the median. Interpret this value in context.

b. Calculate the mean high temperature from last year. Show your work.

c. Which measure of center better describes a typical high temperature? Justify your answer.

64

58.5°

Step-by-step explanation:

Given the data:

22, 31, 64, 64, 42, 81, 79, 71, 79, 79, 52, 38

Rearranged data: 22, 31, 38, 42, 52, 64, 64, 71, 79, 79, 79, 81

The median temperature will be :

1/2(n + 1)th term.

n = 12 (number of samples)

0.5 * (12 + 1)th

= 0.5 (13th)

= 6.5 th term

(6th + 7th term) / 2 = (64 + 64) / 2 = 64

The middle temperature value is 80°F

The mean temperature value :

ΣX /n

= sum(22, 31, 38, 42, 52, 64, 64, 71, 79, 79, 79, 81) / 12

= 702 / 12

= 58.5° F

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.
