Chapter 3: Q.3.65. (page 113)

In Exercises $3.65 - 3.70$ , we have provided simple data sets for you to practice the basics of finding measures of variation . For each data set determine.
a) Range.
b) sample standard deviation.
$4, 0, 5$

Short Answer

Expert verified

$a) R a n g e = 5 b) S a m p l e s \tan d a r d d e v i t a t i o n = 2.65$

Step by step solution

Step 1. Given information.

We have given data : $4, 0, 5$

Step 2. Range of the data.

$R a n g e = M a x . v a l u e - M i n . v a l u e R a n g e = 5 - 0 R a n g e = 5$

Step 3. Standard deviation of the data

$s = \sqrt{\frac{\sum_{} {(x - x)}^{2}}{n - 1}} = \sqrt{\frac{{(4 - 3)}^{2} + {(0 - 3)}^{2} + {(5 - 3)}^{2}}{3 - 1}} = 2.65$
