Answer:

^Definition of grouped data:

•Grouped data are data formed by aggregating individual observations of a variable into groups, so that a frequency distribution of these groups serves as a convenient means of summarizing or analyzing the data.

^GROUPED FREQUENCY DISTRIBUTION

Determine the highest score H and the lowest score L. ...

•Estimate the class width w by dividing the range by a number of groupings or classes. ...

•Set up the class intervals. ...

•Tally the corresponding number of scores in each interval. ...

•H = 48, L = 15; hence the range is d = 48 – 15 = 23.

^Grouped Frequency Distributions

•There should be between 5 and 20 classes.

•The class width should be an odd number. ...

•The classes must be mutually exclusive. ...

•The classes must be all inclusive or exhaustive. ...

•The classes must be continuous. ...
