Question

What does a large standard deviation suggest ?

a. Sources are not normally distributed,

b. Sources are widely distributed?

Answer 1

A low standard deviation indicates that the data points tend to be close to the mean (also called the expected value) of the set, while a high standard deviation indicates that the data points are spread out over a wider range of values.
Hope this helps you

Answer 2

Answer:

A large standard deviation suggests that the sources are widely distributed.

Correct answer is option (b).

Step-by-step explanation:

A standard deviation is defined as a measure of how dispersed the data is in relation to the mean.

Explanation for correct option-

(b) Sources are widely distributed.

• A high standard deviation indicates that the data are more spread out and are widely distributed.
• It indicates that data points are above the mean.
• If we plot a graph for a high standard deviation, the curve is more spread out.

Explanation for incorrect option-

(a) Sources are not normally distributed.

• Low standard deviation means that the data is clustered around the mean.
• A low standard deviation indicates data points are below the mean value.
• If we plot a graph for a low standard deviation, the curve is more clustered  around the mean.

Therefore, the correct answer is option (b) Sources are widely distributed in a large standard deviation.
