What is the cumulative frequency in a frequency distribution table?Group of answer choicesThe sum of the frequencies up to a certain class interval.The total number of data points.The average of the data values.The difference between the highest and lowest data values. PreviousNext

Cumulative frequency is used to calculate:

You are given that the total number of observed values in a frequency distribution is 50 and the frequency of a given class 25-30 is 10. Also, the cumulative frequency of all classes above this given class is 40. The cumulative frequency for this class is

From the given frequency table, find the class mark of the class interval having the highest frequency.

Find the mean for the following frequency tables. (Round your answers to one decimal place.)(a)         Grade Frequency49.5–59.5 259.5–69.5 369.5–79.5 979.5–89.5 1489.5–99.5 5 (b)         Daily Low Temperature Frequency49.5–59.5 5159.5–69.5 3269.5–79.5 1579.5–89.5 189.5–99.5 0 (c)         Points per Game Frequency49.5–59.5 1459.5–69.5 3269.5–79.5 1579.5–89.5 2389.5–99.5 2
