4. Histogram/Boxplot descriptions have to include the following four components in the given order: Shape, center, spread, and outliers.5.Graphdescriptionshavetobeinanessay/paragraph format.
Guiding lines for constructing a Good Histogram:
1.Find Min and Max
2.Choose class width: A ”nice” round number : Width=(Max−Min) / 6
Round Down, unless very close to a ”nice” number
3.Find starting point of 1st interval a ”nice” number such that : min − Width ≤ Start ≤ min
4.Find endpoint of each class
5.Check if range is split to about6-10 classes.

1 Percentage of college students who attend college in their home state.
a. Justification for choosing a histogram
I chose a histogram because, first, we are handling continuous quantitative data to show its

b. Max =61
Min =18
Width = (61 -18)/6 =7.166
Rounding down to a “nice” number we get:
Width =round down (7.166) = 5
Endpoints ={15,20,25,30,35,40,45,50,55,60,65}
