That's a stem and leaf display. The stems are on the left of the
rows of dots and the leaves are on the right of them.
The leaves are the last digits of the data numbers and the stems
are their first digits. So the data numbers are found by putting
the digit on the left of a row of dots with each of the digits
on the right of the row of dots. I'll do them line by line:
1st line: 12, 12, 16, 17
2nd line: 23, 24, 24, 25, 28
3rd line: 33, 33, 33, 35, 36
4th line: 50, 40, 41, 42, 42
5th line: 50, 51
So the set of numbers are these 21 numbers
12, 12, 16, 17, 23, 24, 24, 25, 28, 33, 33, 33, 35, 36, 50, 40, 41, 42, 42, 50, 51
The MOde is the number that appears MOst often which is 33, because it
appears 3 times.
[You can remember that because MOde and MOst both start with MO.]
The median is the middle number when there are an odd number of numbers,
as in this case. So the median is the second 33. I have colored it red.
Notice that there are 10 numbers left of it and 10 numbers right of it.
[You can remember that by the fact that median of a highway is in the middle.]
The range is the largest number minus the smallest number
Range = 51 - 12 = 39
