1

why is empirical research conducted VS why should it be conducted?

often for publicity or politics;

it should be for making better decisions!

2

why is empirical research useful? 2 reasons

1. it challenges implicit bias

2. big data is full of noise

3

empirical research in 6(7) steps

1. Define the Problem

2. Determine Research Design

3. Design Data Collection Method and Form

4.+ Design Sample and Collect Data

5. Analyze and Interpret Data

6. Prepare the Research Report & Presentation

4

how to define the problem: 4 guidelines + 1 goal

cwdl

  1. be precise & clear
  2. ask why
  3. distinguish problem from symptoms
  4. consult scientific literature

=> formulate 1 hypothesis!

5

the hypothesis: def

states the relationship b/w an independent and a dependent variable

6

null VS alternative hyp.

null => conservative hypothesis (no difference)

VS

alternative => new insights

7

hyp. taxonomy on 2 dims

D1:

  • differential = there is a diff
    VS
  • coherence = the higher X, the higher Y

D2:

  • one-tailed = assuming the direction 
    VS
  • two-tailed = not assuming the direction
    of the relationship bw X & Y

8

3 types of research designs

  1. exploratory -
    -> learn about problem & identify research opportunities (used when there is no lit.)
  2. descriptive
    --> describe, like in politics
  3. experimental
    --> uncover causes through manipulation

9

3 sampling options in research design

  • longitudinal
  • cross-sectional
    • single
      or
    • multiple

10

deductive VS inductive method

+ typically

from lit. to hyp. (confirmatory)
VS
from data to hyp. (exploratory) --> typically, you mix

5 req. of ethical social research (2+2+1)

v.i.a.con.fabri.

  1. voluntary participation
  2. informed consent
  3. anonymity
    or at least
  4. confidentiality
  5. no data fabrication
