Question

The sum of the relative frequencies for all classes in a histogram always equals

	a.	the total of all the frequencies.
	b.	the number of classes.
	c.	one.
	d.	none of these answers are correct..
	e.	the class width.

Answer 1

Solution:

Given that,

The sum of the relative frequencies for all classes in a histogram always equals One.

Option C is correct.

The answer is One.

To find the relative frequency, divide the frequency by the total number of data values. To find the cumulative relative frequency, add all of the previous relative frequencies to the relative frequency for the current row.

A relative frequency is the fraction or proportion of times an answer occurs. To find the relative frequencies, divide each frequency by the total number of students in the sample - in this case, 20. The sum of the relative frequency column is or 1.
