The mode is the most common number, which is the number with the highest frequency - that is 20.
The median is the middle number. There are a total of 72 numbers, so the median is the average of the 36th and 37th numbers, which is 25.
The mean is the weighted average of the numbers.
`{2(15)+22(20)+19(25)+14(30)+3(35)+4(40)+6(45)+1(50)+1(55)}/72 approx 27.8`
The mean is 27.8, the median is 25 and the mode is 20.
