How to find a percentage from a histogram

by Mrs. Hoss

​To find the percentage...

​1) Find the total by adding all the bar heights.

2) Take the number for that bar divided by the total.

​3) Change the decimal to a percent by moving the decimal 2 places to the right.

​

​Example: What percentage of weights were 9.08-9.10? Round to the nearest whole #.

​

​9/35 = 0.25714...

​26%
