You want 10 classes with a "nice" class width. Your classes should be labeled using interval notation. Each class contains its lower class limit, and the lower class limits should all be multiples of the class width. In that the data appears to be discrete, use a closed-interval to label each class.

Find the minimum and maximum of the data. 1. Create a stemplot of the data. 2. Organize the stems of the stemplot. 3. Create a new stemplot by splitting the stems. 4. Make a frequency table of the data, with a first interval of “19-22": 5. Create a histogram of the data from the frequency table. 6. Check your work by replicating the histogram on your calculator.

Number of classes: 10 Use a "nice" class width, such as a multiple of 5 or 10. Label classes using interval notation. For example, if the class is 70-79, label it as [70,79]. The lower class limit should be a multiple of the class width. For example, if the class width is 10, the lower class limit should be a number like 30 or 40 (depending on the data).
