Chapter 7 Probability And Samples

Question 1

Distribution of sample Means

Answer 1

The distribution of sample means is the collection of sample means for all the possible random samples of a particular size (n) that can be obtained from a population.

Question 2

Sampling distribution.

Answer 2

A sampling distribution is a distribution of statistics obtained by selecting all the possible samples of a specific size from a population.

Question 3

Sampling distribution

Answer 3

A sampling distribution is a distribution of statistics obtained by selecting all the possible samples of a specific size from a population. Also called the sampling distribution of M.

Question 4

Sampling error

Answer 4

Sampling error is the natural discrepancy, or amount of error, between a sample statistic and it’s corresponding population parameter.

Question 5

Central Limit theorem

Answer 5

For any population with mean, and standard deviation , the distribution of sample means for

Question 6

Expected value of M

Answer 6

The mean of the distribution of sample means is equal to the mean of the population of scores, u, and is called the expected value of M.
