Question

1.1

Given:

mean = 6

median = 8

standard deviation = 3.5

Is the data:

Symetrical

Positively skewed

Negatively skewed

1.2

A value that is typical or representative of the data is referred to as a measure of central tendency.

ii.

The arithmetic mean is the sum of the observations divided by the total number of observations

iii.

The value of the observation in the center after they have been arranged in numerical order is called the weighted mean

(i) and, (ii) are correct statements but not (iii).

(i), (ii) and (iii) are all correct statements

(i) and, (iii) are correct statements but not (ii).

(ii) and, (iii) are correct statements but not (i).

Symetrical

Positively skewed

Negatively skewed

1.1 Here mean is less than median hence the distribution will be skewed left side.

Hence it is c. Negatively skewed
