________ is a method of adjusting for nonresponse in which the researcher tries to discern a trend between early and late respondents.This trend is projected to nonrespondents to estimate their characteristic of interest.

Question 64

When using the confidence interval approach to sample size determination,if the statistic of interest is a proportion,rather than a mean,the approach to sample size determination is very different.

Question 67

Prior notification increases response rates for samples of the general public because it reduces surprise and uncertainty and creates a more cooperative atmosphere.

Question 68

A ________ is a summary description of a characteristic or measure of the sample.It is used as an estimate of the population parameter.

(Multiple Choice)

Question 69

When the sample size is 10 percent or more of the population size,the standard error formulas will overestimate the standard deviation of the population mean or proportion.Hence,these should be adjusted by a finite population correction factor.
