In this section, you will learn how to make a, Frequency Distribution table for Grouped data, The frequency distribution table for grouped data is also known as the. For example, in the table above, each age range is a class, so there are 6 classes. Add the length of the class interval to the starting value to determine the lower value in the subsequent class interval. In this case, the data range is 9821 = 77 98 - 21 = 77. The frequency for three miles should be one; for two miles (left out), two. Table \(\PageIndex{4}\) represents the heights, in inches, of a sample of 100 male semiprofessional soccer players. What is the percentage of deaths that occurred in 2004? In our age list, the minimum value is 35 and the maximum value is 74, so the data range = 74 35 = 39. .
