When you have a sample population that is more spread out, which of the following would most likely be true?

Group of answer choices

a)The distance between scores decreases; which means that a single score, like a mean provides a less accurate representation of the population.

b)The distance between scores increases; which means that a single score, like a mean provides a less accurate representation of the population.

c)The distance between scores increases; which means that a single score, like a mean provides a more accurate representation of the population.

d)The distance between scores decreases; which means that a single score, like a mean provides a more accurate representation of the population.

Answer #1

The Correct aanswer to this Question is Option (B)

Reason : When we have a sample population that is more spread out then the distance between scores increases because population is more spread out and it means that a single score, like a mean provides a less accurate representation of the populatio because we would not be able to cover all the population accurately.

All the other options i.e. (a),(c),(d) are opposite to option (b) and therefore incorrect.

Only Option (B) is correct i.e. The distance between scores increases; which means that a single score, like a mean provides a less accurate representation of the population.

Why is it important to compute confidence intervals for estimates of population means or percentages? A. Because every sample statistic is subject to error. B. Because managers don’t like point estimates. C. Because every sample statistic must be presented without error. D. Because the sample statistic = the population parameter. The calculated z or t value is inversely related to the size of the differences between two means or percentages (i.e., as the difference between two means or percentage increases,...
