Answer 3

OK. Take each number and count the number of occurrences.
46 - 1occurrence
63 - 1
31 - 2
49 - 2, and so on.
Check the total number of occurrences is the same as the total number of raw data numbers (50)
Re-order your occurence list from the smallest raw number to the largest
Plot a graph of the smallest raw number to the largest on the x-axis and the number of occurrences on the y-axis as a histogram.

Do you know what a histogram is?
