So I\'m supposed to create a TRUE experiment on a subject I can find a published

Question

So I'm supposed to create a TRUE experiment on a subject I can find a published survey on that has established reliability and internal validity. My teacher can't explain how to do this for the life of her and everyone in the class in confused considering its online. Is there anyway someone can help me with the below material and possible give a vague example? I can go more in-depth with it myself but I'm pretty much desperate at this point to get it done. Thank you to anyone who assists me with this, it is greatly appreciated!

What are your IV(s) and DV(s)?

What are the levels of your IV(s)

Clearly describe methods used (survey and data collection)

            Describe how this is a true experiment   

Demonstrated covariance (from research article)   

Describe how you are ensuring temporal precedence   

Internal validity:

Random assignment (explain)

What variables might interfere with your outcome?

      How will you control for each of these variables?   

Determine a manipulation check

Statistical validity: What is reliability and validity of survey

      What statistics are relevant for your experiment?

Explanation / Answer

The dataset for the above work is the General Social Survey Dataset 2014.

Independent variable:Respondent age

Dependent variable:Respondent income(Dollar)

The General Social Survey dataset is very much reliable as the sample size is very large concering US population).

Population :US population

Sample:Part of US population randomly selected(approx2500).

Data is collected based on interview question asked to the respondent and it may have biasnes as the answer given by the respondent may not be reliable.

It is a true experiment design as it studies the cause and effect relationship between income and age of the respondent.

Random assignmnet:As the population has been randomly selected.

Shortcomings:The response recieved in interview may be biased.
