Histogram for Heights of Students

The following data includes the heights of students in two Statistics classes at WCC during 2012 and 2013. 1. Highlight column A to get all of the 32 items selected. 2. Select the One Variable Analysis Button (next to the arrow button). 3. Select the Analyze button. A histogram appears. The histogram varies in shape as the number of classes changes. Change the number of classes by moving the bar above the histogram from left to right.
In your opinion, how many classes shows the best distribution of the data? Pull down the Histogram arrow just left of the classes bar, and select dot plot, stem & leaf diagram, or box plot. Which of these look most similar to the histogram you think is best? www.battaly.com/stat/
