The temperature at noon in LHR ,Pakistan was 6 deg on Monday ,4deg on Tuesday,2deg below zero on Wednesday,3deg below zero on Thursday, 0 deg on Friday ,3 deg on Saturday ,and 6 deg on Sunday. What was the average temperature at noon for the week ?

Correct answer: C. 2 deg

  • A. 14 deg
  • B. -2 deg
  • C. 2 deg
  • D. 7 deg

Explanation

The weekly temperatures are 6, 4, -2, -3, 0, 3 and 6 degrees, whose sum is 14 degrees. Dividing by 7 days gives an average of 14 / 7 = 2 degrees. Option b, -2 degrees, results from overlooking the positive temperatures or mishandling the below-zero readings.

About Averages

An average represents the total of a set of values divided by the number of values, and a weighted average gives different importance to different groups. Problems involve missing values, combined averages, replacement of observations, and changes in the average, so the total and count must be tracked separately.
