4 Qs to answer in reporting research & results, with corresponding sections

  1. why, with what expectations did you conduct your study? => intro & theory section
  2. How did you carry out your study? 
    => method section
  3. What did you find? according to APA guidelines
    => result sections
  4. So what are the theoretical & managerial implications, relative to prior findings in the area and with limitations?
    => discussion section

Explanation of Prof. Scherer's experiment

  • Attribution process of good/bad result when interacting with humans/machines, through a between-subjects design.
  • There are conflicting theories predicting 1) more extremes evaluations with humans, 2) same response.
  • An ANOVA analysis did not find any significant difference in results.

3

Sample rule of thumb

have at least 30 subjects for each condition

4

suspicion probe:

  • how
  • against what

 

  • ask subjects what they think the experiment was about
  • you want to exclude those who guessed, to avoid desirability bias and related experiment artifacts (behaving as if...)

5

evaluating other people's studies: 4 guidelines + takeaway

  1. which kind of research design was used?
  2. how were IVs manipulated and DVs measured?
  3. how much and which data is included VS missing?
  4. how was data analyzed?
    1. groups defined how
    2. outliers treated how
    3. covariates & control variables used
    4. statistical power of the tests

=> even researchers make mistakes!

6

evaluating mgmt research: 4 criteria

  1. internal validity
  2. external validity
  3. measurement validity
  4. reliability (replication studies are often not published!)

7

what is highly valuable in research?

multi-method research!

"methodological triangulation" i.e. combining different approaches
