In a frequency polygon plot why do we add extra class interval with frequency zero, one before and one after the given class intervals?
By doing so it enables us to make the area of the frequency polygon the same as the area of the histogram.
To complete the frequency polygon plot we assume a class interval with frequency zero and add one before and one after the given class intervals
State true or false. To complete the frequency polygon plot we assume a class interval with frequency zero and add one before and one after the given class intervals.
To complete the frequency polygon plot we assume a class interval with frequency zero and then ________ .
In a frequency distribution table, the class interval 150-160 is attached with the frequency 15. So the point on the frequency polygon corresponding to this is
