About this unit
In statistics, we try to make sense of the world by collecting, organizing, analyzing, and presenting large amounts of data. For example, you may survey your friends about what tv show is most popular, but the small sample size will not give you an accurate idea of what ALL 6th graders like to watch. To do this you must survey a cross section of students from all around the country and all backgrounds. The data can then be statistically analyzed to give a more accurate picture of what tv show is most popular. So let's dive into a discussion of statistics, including box and whisker plots, bar charts, pictographs, line graphs, and dot plots.

Quiz 1
Problem
A histogram titled, Balls made in each game of Watson's Billiards Tournament, plots Number of games, versus Number of balls made, from 0 to 15, in increments of 3. There is no bar between 0 and 3. Bar heights are approximately as follows. From 4 to 7, 1. From 8 to 11, 5. From 12 to 15, 8.
How many more games had 121212 to 151515 balls made than 444 to 777 balls made?
