24, 31, 12, 38, 12, 15
- Mean: 22, median: 19
- Mean: 22, median: 19.5
- Mean: 21, median: 19.5
- Mean: 23, median: 19.5
Hint:
Mean is the average of the given numbers and is calculated by dividing the sum of given numbers by the total number of numbers.
The median is the middle number in a sorted, ascending or descending list of numbers.
The correct answer is: Mean: 22, median: 19.5
Arranging the data in the increasing order we get.
24, 31, 12, 38, 12, 15
12, 12, 15, 24, 31, 38
Mean =
The median of the data with 6 elements (i.e even) is the average of the 3rd and 4th elements.
Median =
Therefore, The mean is 22, median: 19.5
Therefore, The mean is 22, median: 19.5
