Create a histogram displaying the top ten women's figure skating scores for the 2010 Winter Olympics
The x-axis needs to span from at least 171 to 229 in order to accommodate all of the data.
Since we are not given a specific bin width we can create a histogram with whatever width we choose. It is easiest to pick a nice round number like 5 or 10, but it really depends on how the data is spread. We choose a bin width of 10 points.
Now we look at the data and find how many skaters scored in each interval. The highest will be 180-190, with a frequency of 4, so we need to make sure that our y-axis spans to at least 4.
Finally we plot the frequency of each interval: 2 between 170-180, 4 between 180-190, 1 between 190-200, 2 between 200-210, and 1 between 220-230.
