Histograms and Frequency Tables

After reviewing the problem solving worksheets, we looked at the special features of a histogram. Titles, labels, equally spaced intervals, and ruled lines are all important features of the histogram. We also talked about the difference between tally marks and frequency. Tally marks are just slashes (crossed at each group of 5) while frequency is represented by an actual number. The cumulative frequency can be thought of as the running total.

Tonight's Homework: Make two tally/frequency tables; one should be of the 7th grade test results and the other should show the 8th grade test results. You will be using these tables in class tomorrow.
