Course 1 6-5 Frequency Tables and Histograms A frequency table tells the number of times an event, category, or group occurs. The cumulative frequency column shows a running total of all frequencies.
21
Course 1 6-5 Frequency Tables and Histograms Additional Example 2: Making a Cumulative Frequency Table Step 1: Make a row for each pattern. Step 2: The frequency is how many times each pattern occurred. Number of Fingerprint Patterns Fingerprint PatternFrequencyCumulative Frequency Whorl Arch Loop Step 3: Find the cumulative frequency for each row by adding all frequency values above or in that row. 6 5 11 16 55 Use the tally table in Additional Example 1 to make a cumulative frequency table.

Course 1 6-5 Frequency Tables and Histograms A histogram is a bar graph that shows the number of data items that occur within each interval.
28
Course 1 6-5 Frequency Tables and Histograms Additional Example 4: Making a Histogram Use the frequency table in Additional Example 3 to make a histogram. Step 1: Choose an appropriate scale and interval. Step 2: Draw a bar for the number of students in each interval. The bars should touch but not overlap. Step 3: Title the graph and label the axes.
