ملخص الدرس

This lesson introduces the ascending cumulative frequency table as a way to organize data from a frequency table with intervals. It explains how to construct such a table and represent it graphically using an ogive (cumulative frequency curve). The lesson also covers how to extract information from the table and graph, such as the number of data points less than a certain value.

هتتعلم إيه فى الدرس ده

• An ascending cumulative frequency table shows the number of data points less than the upper limit of each interval.
• The graph of the cumulative frequency is called an ogive.
• The cumulative frequency curve can be used to find the number of data points less than or greater than a given value.
• Percentiles can also be estimated from the cumulative frequency curve.
