You  should post your answers to the individual discussion questions to this  forum by 11:59 p.m. on Friday, February 27th. Then, you will need to  offer some input with respect to what other students have written.

Individual Discussion Board Questions:

1.) What is the “Hawthorne effect,” and how might it impact an  experimental design? What are some ways that researchers might control  for this effect?

2.) What are the eight sources of internal invalidity? How might they  affect the results of a study? With respect to your study, which  sources, do you think, would be most problematic? Why? What actions will  you take to address these issues?

3.) Why is generalizability a major issue when it comes to  experimental designs? Is there anything that researchers can do to  improve an experiment’s generalizability? If so, what? If not, why not?

4.) Hansen and Tummers (2020) examine the notion of field experiments  as they apply to public administration. What are some of the  considerations that researchers must take into account when designing  public-sector field experiments? Discuss. Does our second article of the  week, by Menger and Stein (2018), take these considerations into  account? Is there anything that Menger and Stein could have done to  improve their field experiment?
