Population and means
Consider some test score (or other interval level measurement) that is important in your field of specialization (GENERAL PSYCHOLOGY).<\/p>\n
Consider that you have, in a database, the entire population of scores for people in a defined geographic area, and they are slightly skewed, but reasonably close to normal. Assume you randomly selected a sample of 75 scores, computed the mean of the sample, and then left the scores in the list to be selected again later.<\/p>\n
You then repeated this process 1000 times. In the end, you would have 1000 means for 1000 random samples.<\/p>\n
Explain three things you would be able to predict about the relationship between the population and the list of 1000 means.<\/p>\n
QUESTIONS?<\/p>\n
How is a z score computed?<\/p>\n
What two known quantities of a sample must be available to compute it?<\/p>\n
Explain the relationship between a z score and a standard deviation.
A sample of scores has a mean and standard deviation.<\/p>\n
What are the corresponding quantities in a sampling distribution?<\/p>\n
How does a sampling distribution compare to a distribution of scores?<\/p>\n
For a single population (a large set) of scores, how many sampling distributions exist (including the raw score distribution itself) that have sample sizes less than 64?<\/p>\n
For a given population, explain which of the two sampling distribution parameters change, and how it changes, as sample size increases.<\/p>\n","protected":false},"excerpt":{"rendered":"
