Provide an appropriate response.Explain the difference between a frequency distribution and a relative frequency distribution. Comment on the differences on the vertical axis scale. Given the same data set and the same classes, will the shapes of the frequency distribution and the relative frequency distribution be the same? You may draw a diagram to support your answer.
What will be an ideal response?
Answers will vary. Possible answer: The frequency distribution and the relative frequency distribution for a given set of data both have the same shape but have different scales on the vertical axis. Given the scale for the frequency distribution, the scale for the relative frequency distribution is obtained by dividing each number on the vertical axis by n (the size of the data set).
