Answer 1

The correct result to the question would be mean.

The mean (average) is found by calculating the sum of all data in the set divided by the number of data values in the set.
The median is the middle value in the list of data values.
The mode is the value which occurs most often.
The interquartile range is the difference between the third and the first quartiles.
