I. Directions: Dowhat is asked. Determine whether the following statements are true or false. The group surveyed when the survey is not administered to all members of the population is called a sample. 1. ll. . Sampling can be done when it would be impractical to survey the entire population. .Thec hoice of sampling technique is dependent on the research questions and objectives and the achievability of gaining access to the data Simpl e random sampling involves creating subgroups of the entire population, usually based on the geographic location. . Cluster sampling is uses strata in determining samples. Choose the letter of the best answer. 1. Which of the following employs simple random sampling? a. b. c. d. 2.A picking a house randomly and then picking 5 more on the same street drawing names randomly from a covered box selecting every 10'" person that you see picking a random location on a map and then the nearest two houses are chosen teacher divides her classroom into juniors and seniors. In each group, she divides her students into boys and girls. From each of these four new groups, she picks one student randomly. What type of sampling method does she use? b. c. d. cluster sampling multistage sampling stratied random sampling systematic random sampling 3. Cluster sampling, stratied sampling. and systemch sampling are types of what kind of sampling method? b. c. d. direct sampling indirect sampling random sampling non random sampling 4. This is a type of sampling where each element of the population has an equal chance of being included in the sample. a b. c. d. Irregular sampling error free sampling cluster sampling simple random sampling 5. Interviewing all members of a given population is called alan . a. sample c. audit b. census d. experiment 6. If a researcher selected ten schools at random and then interviewed ead'I of the teachers in those schools. the researcher used what kind of sampling method? a. simple random sampling b. stratied random sampling c. cluster random sampling d. two-stage random sampling Use the following information for questions 7 and 8: A researcher who wanted to determine the benets of using a new study technique to Statistics students obtained permission from a school district to select 50 senior high school students as participants. The researcher selected 50 senior high school students at random. The researcher selected 25 of them to participate in the new study program. The researcher gave a training session on traditional study techniques to the other 25 students and asked them to use these methods. 7. Who is the target population in this study? a. Statistics students In the district b. All students in the district c. All Statistics students d. The 25 students who learned the new study techniques 8. What method of sampling is used in the study? a. simple random sampling b. Stratied random sampling c. cluster sampling d. convenience sampling 9. How Is stratified sampling carried out? a. Divide the population into homage-nous groups and proportionally select random sample from each group. b. Systematically choose samples by getting. say. every 8'\" entry in a list. it. Divide the population into groups and select all members of a random group as samples. d. Assign numbers to each member of the population then randomly select numbers 10.Which is an advantage of using simple random sampling? a. It eliminates risk of getting biased respondents. b. It is easy to use and likely represents the population c. It is the easiest to use if the target population is spread out in a large geographical area. d. It has been established in the courts to be superior to stratied random sampling
