Question

Two groups of students were asked how far they lived from their school. The table shows the distances in miles: Group A (distance in miles) 1 1. 5 3. 03 03. 2 2. 8 1. 5 1. 8 2. 5 2. 2 Group B (distance in miles) 2 2. 5 3. 23 1. 3 1. 8 2. 4 3 2001. 5 1. 8 Which statement best compares the mean distances for the two groups? It is equal for Group A and Group B. It is greater for Group B than Group A. Its value for Group A is double the value for Group B. Its value for Group B is double the value for Group A.

Answer 1

The mean is equal for Group A and Group B.

Given

Two groups of students were asked how far they lived from their school.

The table shows the distances in miles:

Group A (distance in miles) 1 1.5 3.03 3.2 2.8 1.5 1.8 2.5 2.2

Group B (distance in miles) 2 2.5 3.23 1.3 1.8 2.4 3 1.5 1.8

What is mean?

The mean of any data set or observation is equal to the sum of all the observations and divided by the number of observations.

The formula used to calculate the mean is;

$\rm Mean = \dfrac{Sum \ of \ all \ observation}{Number \ of \ obrservation}$

The mean of group A is;

$\rm Mean = \dfrac{Sum \ of \ all \ observation}{Number \ of \ obrservation}\\\\\rm GroupA \ mean = \dfrac{1 + 1.5 + 3.03 + 3.2 + 2.8 + 1.5 + 1.8 + 2.5 + 2.2}{9 }\\\\\rm Group A \ mean=\dfrac{ 19.53}{9}\\\\ Group A \ mean = 2.17$

The mean of group B is;

$\rm Mean = \dfrac{Sum \ of \ all \ observation}{Number \ of \ obrservation}\\\\\rm Group B \ mean = \dfrac{2 + 2.5 + 3.23 + 1.3 + 1.8 + 2.4 + 3 + 1.5 + 1.8}{9} \\\\Group B \ mean = \dfrac{19.53}{9}\\\\ Group B \ mean = 2.17$

Hence, the mean is equal for Group A and Group B.
