Survey Design

A school newspaper is going to investigate students' perceptions regarding the campus security guards. They plan to survey 100 students at the school. The editor-in-chief tells his staff that he is worried about undercoverage bias created by chronically truant students. His concern is...

• unwarranted because some students may refuse to participate and that is inevitable.

• justified because chronically truant students will be difficult to survey and will probably have a disproportionately negative view of security guards.

• unwarranted because students who cannot be surveyed are not a part of the population of interest.

• unwarranted because students who cannot be surveyed are not a part of the sample.

• justified because people need to be forced to answer a surey in order for the results to be valid.

A high school statistics class wants to conduct a survey to determine what percentage of students in the school would be willing to pay a fee for participating in after-school activities. Twenty students are randomly selected from each of the freshman, sophomore, junior, and senior classes to complete the survey. This plan is an example of which type of sampling?

• Cluster

• Convenience

• Simple Random

• Stratified random

• Systematic

This research method is a technique for ascertaining the self – reported attitudes or behaviors of a particular group, usually by questioning a representative, random sample of the group.

• Survey

• Observational

• Correlational

• Experiments

• Case Study

Ana wants to know the average student’s opinion of the tardy policy at her school. Which group of students should she survey in order to achieve the most accurate results?

• thirty students who are often tardy

• thirty students who are rarely tardy

• thirty of her friends

• thirty randomly selected students from her school

Random sampling minimizes bias and skewness.

• True

• False

Disneyland often surveys its guests as they exit a restaurant during their visit. The surveyor stands at the restaurant exit, counts the number of people leaving, and surveys every 25th guest.
This is a form of:

• Simple Random Sample

• Stratified Random Sample

• Voluntary Response

• Systematic Random Sampling

A teacher wants to know how well her students are doing on a topic. She randomly picks one class to survey.

• Simple Random
