Chapter 6 - Sampling and Populations Worksheet
Across
- 2. How certain we are that a confidence interval includes the true population mean (proportion).
- 3. A nonrandom sampling method whereby the researcher includes the mose convenient cases in his or her sample.
- 14. A random sampling method whereby a table of random numbers is employed to select a sample that is representative of a larger population.
- 15. An estimate of the standard deviation of the sampling distribution of means based on the standard deviation of a single random sample.
- 17. A smaller number of individuals taken from some population (for the purpose of generalizing to the entire population from which it was taken).
- 18. A random sampling method whereby the population is first divided into homogeneous subgroups from which simple random samples are then drawn.
- 19. The extent of imprecision expected when estimating the population mean or proportion.
- 20. A nonrandom sampling method whereby logic, common sense, or sound judgement is used to select a sample that is presumed representative of a larger population.
Down
- 1. A random sampling method whereby every nth member of a population is included in the sample.
- 4. The range of mean values (proportions) within which the true population mean (proportion) is likely to fall.
- 5. The range of mean values (proportions) within which there are 95 chances out of 100 that the true population mean (proportion) will fall.
- 6. The range of mean values (proportions) within which there are 99 chances out of 100 that the true population mean (proportion) will fall.
- 7. In small sample comparisons, a statistical compsensation for the failure of the sampling distribution of differences to assume the shape of the normal curve. Written as df.
- 8. A type of probability function that is appropriate for estimating population parameters for small sample sizes or unknown variances.
- 9. A sampling method whereby each population member does not have an equal chance of being drawn into the sample.
- 10. Any set of individuals who share at least one characteristic.
- 11. The probability of commiting a Type I error.
- 12. A nonrandom sampling method whereby diverse characteristics of a population are sampled in the proportions they occupy in the population.
- 13. A sampling method whereby every population member has an equal chance of being drawn into the sample.
- 16. A random sampling method whereby members are selected on a random basis form a number of well-delineated areas known as clusters (or primary sampling units).
