Mean, Median, Mode and Cumulative Frequency Practice Problems

Set 1: Cumulative Absolute Frequency

Review the concepts of cumulative absolute frequency at Statistics Terms Help.

Practice

Draw a vertical bar graph showing all the absolute-frequency data from Table 7-5, the results of a “weighted” die-tossing experiment. Portray each die face on the horizontal axis. Let light gray vertical bars show the absolute frequency numbers, and let dark gray vertical bars show the cumulative absolute frequency numbers.

Table 7-5 Results of an experiment in which a “weighted” die is tossed 6000 times, showing absolute frequencies and cumulative absolute frequencies.

Solution

Figure 7-6 shows such a graph. The numerical data is not listed at the tops of the bars in order to avoid excessive clutter.

Set 2: Cumulative Relative Frequency

Review the concept of cumulative relative frequency at Statistics Terms Help

Practice

Draw a horizontal bar graph showing all the relative-frequency data from Table 7-6, another portrayal of the results of a “weighted” die-tossing experiment. Show each die face on the vertical axis. Let light gray horizontal bars show the relative frequency percentages, and dark gray horizontal bars show the cumulative relative frequency percentages.
