MediaResearch: Research Ethics: Tuskegee, Lacks, Milgram & Zimbardo (W15-P3) Sp19


Research ethics are the moral principles and rules that guide a researcher’s actions.

Why talk about research ethics?  What is the need?

To answer that question, let's look at some important research studies from the past.
When watching these clips ask yourself what ethical concerns are raised in doing this research.

1) Tuskegee Syphilis Experiment




2) The Immortal Life of Henrietta Lacks




3 & 4) Milgram's Authority Study & The Stanford Prison Experiment
(Watch from 0:00 to about 6:30)



What are the ethical concerns with the research that Milgram and Zimbardo did? Would you feel comfortable doing this research? Would such research be allowed today?

O.K., now that you have some knowledge of these past experiments do you have an answer to the questions asked earlier?  Why talk about research ethics?  What is the need?


If you are curious, there are some recent films and documentaries about some of these above examples of research misconduct.

MediaResearch: Experiments: What is an Experiment? (W15-P1) Sp19


Play the first minute or so.


When you think of a person doing science, doing research, doing an experiment, what images pop into your mind?

Have film and television shaped your view of science and of experiments?
Hey, I feel a research question coming on.  We could research that.

If it is not the Frankenstein movies that have shaped your image of scientists doing experiments, what movies or television shows have?




An experiment is a research methodology for determining the causal effects of one or more independent variables on a dependent variable, while controlling for all intervening variables.

Experiments are only one of the possible research methodologies you could use to answer your research questions.  Surveys and interviews, for example, are other research methodologies.  There are benefits and drawbacks when considering which research method to use to answer a research question.  What are some benefits that experiments have, but surveys do not?  What is it that experiments can do, that surveys cannot?


What is meant by causal relationship or causal effect?
Or put another way, to be able to say one thing caused another, what would need to be true?

  1. Independent variable comes before the dependent variable.
  2. Independent and dependent variables are meaningfully related.
  3. Changes in DV must be the result of changes in IV (and not anything else)
Watch the clip below.
Correlation vs. Causality: Freakonomics Movie



If you are interested, check out "Correlation and Causality (Khan Academy - YouTube),"
Also, if interested, check out, Correlation or Causation? (Some headlines) or Correlation vs. Causation (NYT)

What is experimental control?
The ability to rule out alternative explanations for the results, controlling for all intervening variables.
You want the IV to be the only thing causing a change in the DV.

In real estate, it is location, location, location.
In experiments, it is control, control, control.

How can experimental control be enhanced?

Compare experimental control in the lab vs. field study.
  • In lab, can more easily manipulate IV.
  • In lab, can randomly assign participants TR and C groups
  • In lab, can control extraneous variables.
  • In field, max external validity

MediaResearch: Experiments: How to Design an Experiment (W15-P2) Sp19


If you wanted to do an experiment, there are three general ways of doing it.


First, a quick question: Based on the name alone, which do you think is the worst form of experimental design?  Why?

Now let's look at each.


The diagrams in these slides explain how to do the different types of experimental designs.
Read these slides from left to right, starting with the random assignment of subjects into the treatment and control groups.  For each design, what are the steps after the random assignment?  That is, how do you do these types of experiments?

So, Post-test ONLY Control is a good design, but there is a problem.  Are we sure that the IV caused a change in the DV?  How would a pre-test help?


Again, this is a good experimental design.  However, there is a potential problem with this too.  Before the pre-test helped.  Now, the pre-test could be a problem.  How's it a problem?


How does the Solomon Four Group design help control for the possible influence of the pre-test?

The above designs are sub-types of full experiments with one independent variable.

However, what if you wanted to have more than on IV in your study?  How would you design an experiment for that?



Now, let's wrap up with a look at the "worst" designs.



If these are the "worst" designs why are we talking about them?  When would you use them?  Better than nothin'?

Which is better a quasi-experimental design or a pre-experimental design?  Why?  What standard are you using to judge whether one is "better" than another?

Speaking of experiments, catch the film reference in the last slide?
