Question

A maths teacher is analysing the marks of her cclass in a recent exam. she has noted the following: max score: 77 min score: 34 mean score 52 modal score: 49. next day she adds another student's score 95, who took the test another day. which of the following measures will NOT change as a result: Range, Max Value, Min Value, Mean, Median or Mode?

Answer 1

The minimum value and mode

Explanation:

range: the earlier range was 77-34 but now that there is a higher score the range will change to 95-34

max value: earlier the maximum value was 77, but this student scored 95 which is higher than 77

mean: the average will change as there is a new number, which is not the mean, in this case 52.

median: as another number has been added, the previous number will not be in the middle any more.
