Chapter 6: Characteristics of the Sample Mean

Question 1

Which sampling method is used the most in behavioral research?

Answer 1

Experimental sampling

Question 2

Does order matter in theoretical sampling?

Answer 2

Yes, in theoretical sampling, the order of selecting individuals matters

Question 3

Does order matter in experimental sampling?

Answer 3

No, in experimental sampling order does not matter

Question 4

In theoretical sampling, do you select with or without replacement?

Answer 4

In theoretical sampling, each individual selected is replaced before sampling again.

Question 5

In experimental sampling, do you select with or without replacement?

Answer 5

In experimental sampling, each individual selected is not replaced before selecting again.

Question 6

The sample mean is an ____ of the value of the population mean.

Answer 6

unbiased estimator

Question 7

What is the central limit theorem

Answer 7

The central limit theorem explains that regardless of the distribution of scores in a population, the sampling distribution of sample means selected at random from that population will approach the shape of a normal distribution, as the number of samples in the sampling distribution increases.

Question 8

A distribution of sample means follows the …

Answer 8

central limit theorem

Question 9

What is the standard error of the mean?

Answer 9

The standard error of the mean, or standard error, is the standard deviation of a sampling distribution of sample means. It is the standard error or distance that sample mean values deviate from the value of the population mean.
