Quasi-Experiments and Single Factor Experimental Designs

Unit 8 Assignment
Name:
Identify whether a quasi-experiment or single factor experiment would be ideal to use in each scenario in the table below.
Scenario

Term

A researcher wants to see if individuals diagnosed with Bipolar Disorder have more stress than individuals not diagnosed with Bipolar Disorder.

Quasi-Experiment

A researcher wants to see if children born with Fetal Alcohol Syndrome differ from children not born with Fetal Alcohol Syndrome.

Quasi-Experiment

A researcher wants to see if yoga therapy reduces symptoms of depression.

Single Factor Experiment

A researcher wants to assess the consequences of patient non-compliance with following recommendations for managing diabetes.

Quasi-Experiment

A researcher wants to see if a gluten-free diet improves energy.

Single Factor Experiment

A researcher wants to see if daily walking leads to improved sleep.

Single Factor Experiment

Scenario 1
A researcher wants to conduct a between subjects single factor experimental design to assess if a daily walking program reduces anxiety.
Question

Response

What sample would be good to use?

A sample of adults with anxiety would be suitable for this study. The participants would be those above 18 with some anxiety.

What would be the independent variable?

The independent variable in this scenario would be the daily walking program, which the researcher would manipulate to observe its effect on the dependent variable.

What would be the dependent variable?

The dependent variable in this scenario would be the level of anxiety; this is the variable that the researcher would measure to determine how the independent variable affected it.

Why would a single factor experimental design be ideal here?

A single-factor experimental design is ideal for this scenario because it allows for a comparison between the group that does the walking program and the group that does not. Specifically, this design would compare the anxiety levels of both groups to assess whether the walking program has a positive or negative effect on reducing anxiety.

In 3-4 sentences, briefly describe how a between subjects single factor experimental design could be used with this scenario.

In a between subjects single factor experimental design, two groups of participants would be formed. One group would participate in the daily walking program, while the other would not. The anxiety levels of both groups would then be measured and compared to determine if the walking program has an effect on reducing anxiety.
