It may be easier to calculate the median if you rearrange the numbers first.
28
Let's look at the given data set.
Boys | Girls | |
---|---|---|
Ms. Green | 15 | 14 |
Mr. Nesbit | 12 | 12 |
Ms. Jackson | 12 | 16 |
We want to find the median number of students in the three classes. To do this, we will first calculate the number of students in each class. Ms. Green's Students:& 15+14 = 29 Mr. Nesbit's Students:& 12+12 = 24 Ms. Jackson's Students:& 12+16 = 28 To identify the median, we observe the middle value of this set. 24, 28, 29 We can see that the middle value in this set is 28, so this is our median.
