Exam 12: Sampling: Final and Initial Sample Size Determination

________ is a method to adjust for nonresponse by assigning the characteristic of interest to the nonrespondents based on the similarity of the variables available for both nonrespondents and respondents.

In ________,cost does not enter directly into the calculation of sample size.

The ________ is the standard deviation of the sampling distribution of the mean or proportion.

The confidence level is the range into which the true population parameter will fall,assuming a given level of confidence.

When estimating a population parameter by using a sample statistic,the ________ is the desired size of the estimating interval.This is the maximum permissible difference between the sample statistic and the population parameter.

Generally,large samples are desirable in social media research.

Which survey method has the highest refusal rate?

Discuss why there may be ethical concerns when using the standard deviation of a variable in determining sample size.

The cost of increasing the sample size in social media research goes up markedly.

The ________ is called the standard error of the mean or the proportion to indicate that it refers to a sampling distribution of the mean or the proportion,and not to a sample or a population.

The number of interviews that must be completed is the ________.

Nonresponse rates should always be reported and,whenever possible,the effects of nonresponse should be estimated.

Which of the formulas below would be used to determine the sample size using the formula for the standard error of the mean?

The sampling distribution of the mean is a binomial distribution.

The door-in-the-face attempt at motivating potential respondents is more effective than foot-in-the-door.

Which method of improving response rate involves use of the foot-in-the-door or door-in-the-face technique?

When determining the sample size,the standard deviation may not be known.Which of the following was not mentioned in your text as a way to estimate the standard deviation?

If the researcher is required to estimate several parameters,not just one,the calculation of sample size in these cases should be based on a consideration of all the parameters that must be estimated.

The ________ is a correction for overestimation of the variance of a population parameter,e.g. ,a mean or proportion,when the sample size is 10 percent or more of the population size.

Ethical dilemmas associated with sample size determination include all of the following except ________.
