1. Draw the cumulative frequency polygon for the distribution.

2. Draw the corresponding cumulative frequency polygon.

3. With the cumulative frequency method the thresholds of extreme precipitation event was defined according to daily precipitation data of 68 stations in Anhui province during last 40 years.

4. The model types include frequency histogram, cumulative frequency distributing graph and theoretical model with double logarithmic coordinates.

5. With the increasing work pressure, the cumulative frequency of smaller droplet diameter was produced, and the atomization would be better.

6. The model types include frequency histograms, cumulative frequency distribution graphs and theoretical model with double logarithmic coordinates.

7. Multielement characteristics of Chinese human hairs have been studied in cumulative frequency distribution, correlation and in relation to sex and age.

8. Through analyzing the methods of distinguishing traffic accident hazardous locations, the cumulative frequency method was improved. Its corresponding software was programmed.

9. The Six Sigma Black Belt should be able to read values from a cumulative frequency ogive.
