16
Q

helps to control for extraneous variables, assignment of subjects to experimental or control conditions is equally likely by change

A

random assignment

17
Q

systematically selecting homogenous sample from a heterogenous population and randomly assigning sample to experimental or control conditions

A

holding variables constant

18
Q

experimental group members are paired with similar control group members for data analysis

A

matching participants

19
Q

combination of matching and randomization, subjects are first matched on one or more key variables in order to form homogenous groupings. members of each block are then randomly assigned to the experimental or control conditions.

A

blocking variables

20
Q

any specific condition applied to the units

A

treatment

21
Q

both subjects and those who evaluate the outcome are ignorant of which treatment was given

A

double-blind technique

22
Q

whether the independent variable actually produces the effect that it appears to have had on the dependent variable, controlling for extraneous variables

A

internal validity

23
Q

refers to the capacity to generalize casual inferences to other times, settings, or groups of people

A

external validity

24
Q

subjects are observed after treatment was delivered, randomization or control groups are not used

A

pre-experimental designs

25
Q

use randomization and control groups

A

true experimental designs

26
Q

use procedures, other than randomization, to create experimental and control groups. used when conditions do not allow for the use of true experimental design

A

quasi experimental designs

27
Q

comes in the form of words, pictures, narratives and descriptions rather than numbers, relies on views of participants and asks general questions

A

qualitative research

28
Q

researchers in qualitative research take this approach

A

subjective and biased approach

29
Q

type of qualitative research, involves observations made of people in their natural settings and everyday life

A

field research

30
Q

researcher personally experiences the world of the observed

A

participation

31
Q

noting and recording the behaviors of others in social setting

A

observations

32
Q

detailed descriptive study of all or part of a life in an organizational event

A

case studies, life histories and narratives

33
Q

interview with a whole group of people at the same time, led by one or more moderators who direct the discussion by following an outline of the main topics

A

focus groups

34
Q

more flexible, less expensive, faster than individual interviews

A

advantages of focus group

35
Q

less generalized, difficult to analyze, qualitative rather than quantitative

A

disadvantages of focus group
