Exam 4: Quantitative Study Design

Which of the following is a data-collection tool that relies on specific responses and close-ended answers?

What kind of sampling do snowball sampling, quota sampling, and expert sampling reflect?

You have just completed an experimental study design and you would like to claim that the results are an outcome of the treatment variable. What type of validity must you be confident in to make a cause-and-effect relationship claim?

Which of the following types of data is represented by the ranking of your favourite hobbies from most favourite to least favourite?

If you wanted to reduce selection bias, which sampling method would you not use?

Discrete data include which of the following?

Your professor has assigned a project where you are required to replicate the findings from a previously conducted research project. After completing the project, you determine that you are unable to replicate the results. This could represent an issue related to which of the following?

You need to collect a wide range of variables for your research project and you want to use measures that assess anxiety, depression scores, physical activity levels, and physical activity preference. What method of data collection typically involves a mix of rating scales?

Extraneous variables should also be control variables.

In a simple between-groups design, it is important to randomize participants to which of the following?

Compare and contrast a non-experimental study design, a pre-experimental study design, and a true experiment. Discuss the three study designs in terms of random assignment to experimental groups and the presence of an intervention or manipulation.

Reliability reflects the degree to which you have confidence in your conclusions based on the research conducted.

Define external validity and discuss how experimental designs make it difficult to claim.

What is the purpose of administering a pre-test- post-test design? Give an example of how you would administer a pre-test-post-test design.

If you wanted to complete a study comparing adolescent, middle age, and senior adult health related behaviours, which sampling method would be most beneficial to ensure that there is an equal representation of each age group?

What is the big distinguishing feature between a true experimental design and a quasi-experimental research design?

Ordinal data and interval data both involve quantities that are ordered. What is the distinguishing characteristic between the two?

An experimental design consists of an experimental group and a control group.

Threats related to the participations, such as maturation, selection bias, and experimental drop-out, are typically related to what kind of decreased validity?

If the people in your study are not randomly assigned to groups, you are completing a descriptive study design.
