Strategies
Knowledge of statistical vocabulary and the method to read and create histograms are encouraged to ensure success on this exercise.
 * 1) A histogram is mistakenly called a bar chart. Bar charts are for qualitative data, histograms create bins for the bars and are used for quantitative data.
 * 2) The height of each bar represents the number of data points in the interval along the horizontal axis.
 * 3) The sum of the heights of the bars should be the total number of data points.

Real-life Applications

 * 1) Data and statistics appear in news reports and in the media every day.
 * 2) Many of the problems in this exercise could be viewed as real-life applications.
