Cluster sampling

Step by step solution

01

Given information

Three randomly selected classes were surveyed for their driving habits. All students are surveyed for responses from each of the classes.

02

Identify the method of sampling

Cluster sampling collects data in the following steps.

  • It divides the population into different clusters (groups of the same nature).
  • Then selects a certain number of clusters randomly.
  • Finally, it selects all the elements from the selected groups for responses.

In the study, the population comprises all students divided into classes (clusters). Classes are randomly selected, and further, all the students are surveyed from each of the selected classes.

Thus, the sampling method is cluster sampling.

Identify whether the given value is a statistic or a parameter.

Titanic A study was conducted of all 2223 passengers aboard the Titanic when it sank.

In Exercises 17–20, refer to the sample of body temperatures (degrees Fahrenheit) in the table below. (The body temperatures are from a data set in Appendix B.).

Conclusion If we analyze the listed body temperatures with suitable methods of statistics, we conclude that when the differences are found between the 8 AM body temperatures and the 12 AM body temperatures, there is a 64% chance that the differences can be explained by random results obtained from populations that have the same 8 AM and 12 AM body temperatures. What should we conclude about the statistical significance of those differences?

In Exercises 29–36, answer the given questions, which are related to percentages.

Percentages in Advertising: An ad for Big Skinny wallets included the statement that one of their wallets “reduces your filled wallet size by 50%–200%.” What is wrong with this statement?

Statistical Significance and Practical Significance. In Exercises 13–16, determine whether the results appear to have statistical significance, and also determine whether the results appear to have practical significance.

IQ Scores Most people have IQ scores between 70 and 130. For $39.99, you can purchase a PC or Mac program from HighIQPro that is claimed to increase your IQ score by 10 to 20 points. The program claims to be “the only proven IQ increasing software in the brain training market,” but the author of your text could find no data supporting that claim, so let’s suppose that these results were obtained: In a study of 12 subjects using the program, the average increase in IQ score is 3 IQ points. There is a 25% chance of getting such results if the program has no effect.

Health SurveyIn a survey of 1020 adults in the United States, 44% said that they wash their hands after riding public transportation (based on data from KRC Research).

a. Identify the sample and population.

b. Is the value of 44% a statistic or parameter?

c. What is the level of measurement of the value of 44%? (nominal, ordinal, interval, ratio)

d. Are the numbers of subjects in such surveys discrete or continuous?
