Chapter 3: Q 3.12 . (page 101)

We have provided simple data set for you to practices the basics of finding measures of center. For each data set determine the:
a) Mean
b)Median
c) Mode.
The given data set is: $2, 5, 0, - 1$

Short Answer

Expert verified

a) Mean $= 1.5$

b) Median $= 1$

C) Mode does not exist, because no value occurs more than once.

Step by step solution

Step 1. Given information.

The given data is $2, 5, 0, - 1$ .

Step 2. Mean of the data.

Mean $= \frac{S u m o f o b s e r v a t i o n}{N u m b e r o f o b s e r v a t i o n}$

$= \frac{2 + 5 + 0 + (- 1)}{4} = 1.5$

Step 3. Median of the data.

Arrange the data in increasing order $- 1, 0, 2, 5$ .

The number of observation is $4$ .

Median role="math" $= \frac{2 n d t e r m + 3 r d t e r m}{2}$

$= \frac{0 + 2}{2} = \frac{2}{2} = 1$

Step 4. Mode of the data.

Mode does not exist, because no value occurs more than once.
