Chapter 1: Q 1.68. (page 24)

Litigation Surveys. In the article, "Non - probability Sampling Designs for Litigation Surveys (Trademark Reporter, Vol. 81, pp. 169-179), J. Jacoby and H. Handlin discussed the controversy about whether nonprobability samples are acceptable as evidence in litigation. The authors randomly selected 26 journals from a list of 1285 scholarly journals in the social and behavioral sciences. They examined all articles published during one year in each of the 26 journals selected with regard to sampling methods. What type of sampling design was used by these two authors in their investigation? Explain your answer.

Short Answer

Expert verified

Cluster sampling is used in this study.

Step by step solution

01

Step 1. Given information.

The given statement is:

In the article, "Non - probability Sampling Designs for Litigation Surveys, J. Jacoby and H. Handlin discussed the controversy about whether nonprobability samples are acceptable as evidence in litigation. The authors randomly selected 26 journals from a list of 1285 scholarly journals in the social and behavioral sciences. They examined all articles published during one year in each of the 26 journals selected with regard to sampling methods.

02

Step 2. Explanation.

It is given that the population consists of 1285 scholarly journals in the social and behavioral sciences that are grouped into clusters.

Then a random sample of 26 clusters was chosen, and all articles from the selected publications were evaluated.

As a result, we can say that the authors' sampling design for selecting a sample of journals is cluster sampling.

Immunization of Schoolchildren. In the article, "Reasons for Non - uptake of Measles, Mumps, and Rubella Catch Up Immunisation in a Measles Epidemic and Side Effects of the Vaccine" (British Medical Journal,Vol. 310, pp. 1629-1632), R. Roberts et al . discussed a follow-up survey to examine why almost 10,000 children, ages 11-15, whose records showed no previous immunization were not immunized. In the survey, 10 of the 46 schools participating in the immunization campaign were randomly chosen and then the parents of all the nonimmunized children at the 10 selected schools were sent a questionnaire. What type of sampling design was used by these authors in their survey? Explain your answer.

The members of a population are numbered 1-50.

(a). Use Table I in Appendix A to obtain an SRS of size 6 from the population. Start at the two-digit number in line number 10 and column numbers 10-11, read down the column, up the next, and so on.

(b). If you have access to a random-number generator, use it to solve part (a)

Comparing Gas Mileages. An experiment is to be conducted to compare four different brands of gasoline for gas mileage.

(a) Suppose that you randomly divide 24 cars into four groups of 6 cars each and then randomly assign the four groups to the four brands of gasoline, one group per brand. Is this experimental design a completely randomized design or a randomized block design? If it is the latter, what are the blocks?

(b) Suppose, instead, that you use six different models of cars whose varying characteristics (e.g., weight and horsepower) affect gas mileage. Four cars of each model are randomly assigned to the four different brands of gasoline. Is this experimental design a completely randomized design or a randomized block design? If it is the latter, what are the blocks?

(c) Which design is better, the one in part (a) or the one in part (b)? Explain your answer.

Identify some methods used in descriptive statistics.

Adverse Effects of Prozac. Prozac ( fluoxetine hydrochloride ), a product of Eli Lilly and Company, is used for the treatment of depression, obsessive-compulsive disorder ( OCD ), and bulimia nervosa. An issue of the magazine Arthritis Today contained an advertisement reporting on the " ... treatment-emergent adverse events that occurred in 2 % or more patients treated with Prozac and with incidence greater than placebo in the treatment of depression, OCD, or bulimia. " In the study, 2444 patients took Prozac and 1331 patients were given placebo. Identify the

(a) treatment group.

(b) control group.

(c) treatments.
