Lesson Summary
What is the median, mode and mean, in that order, of the following numbers:
20, 22, 19, 26, 44, 15, 37, 40, 25, 23, 26?
A.25, 26, 27
B.27, 26, 25
C.25, 27, 26
D.26, 25, 27
Text Answer
To find the median arrange the numbers in ascending order, i.e from the smallest to the largest as follows:
15, 19, 20, 22, 23, 25, 26, 26, 37, 40, 44
The median is the number in the middle. In this case the number is 25. The mode is the number appearing most times, i.e the number with the highest frequency. In this case the mode is 26.
To calculate the mean add all numbers and divide the total by 11,
i.e mean =5+19+20+22+23+25+26+26+37+40+4411=29711=27
Hence required order: median, mode, mean = 25, 26, 27
The correct answer is A (25, 25, 27).
