Q

What is the purpose of an experiment?

A

to explore cause and effect relationships (i.e. treatments are given to see how they affect the participants)

20
Q

demographics

A

background characteristics such as socioeconomic status

21
Q

causal-comparative study

A

ex post facto study

22
Q

Causal-Comparative Study Essential Characteristics

A
  1. observe and describe a current condition

2. look into the past to try to identify the possible causes of the condition

23
Q

Best study to explore causality?

A

causal-comparative

24
Q

Causal-Comparative Research

A

look into the past for a cause of a current condition

25
Q

Census

A

interview of all members of a population

26
Q

case study

A

study involving only one participant

27
Q

longitudinal research

A

repeatedly measure traits of the participants over a period of time in order to trace developmental trends

28
Q

correlational research

A

interested in the degree of relationship among two or more quantitative variables

29
Q

quantitative research

A

gather numerical data for statistical analysis

30
Q

Qualitative research

A

gather data to be analyzed through informed judgment to identify major and minor themes expressed by participants.

31
Q

Historical research

A

by reviewing historical evidence, researchers are able to develop theories that may explain historical events and patterns and then lead to hypotheses

32
Q

variable

A

a trait or characteristic with two or more categories

33
Q

Mutually exclusive categories

A

each respondent to a survey belongs to only one category

34
Q

exhaustive category

A

a variable must have a category for each respondent’s opinion

35
Q

categorical variables

A

naming variables

36
Q

Independent variable

A

stimulus or input that causes changes; predictor

37
Q

dependent variable

A

response or output; criterion

38
Q

research hypothesis

A

prediction of the outcome of a study

39
Q

directional hypotheses

A

researchers predict which group will be higher or have more of some attribute

40
Q

nondirectional hypothesis

A

researcher says there will be a difference but does not predict the direction of the difference

41
Q

Two options for a nondirectional hypothesis:

A
  1. research purpose

2. research question

42
Q

Null hypothesis

A
  1. statistical hypothesis

2. needs to be considered in analysis

43
Q

Conceptual definitions

A

does not indicate a precise concrete physical steps taken to identify the variable

44
Q

operational definition

A

defining a variable in terms of physical steps

45
Q

replication

A

attempt to confirm the results of a study by conducting it again

46
Q

Program Evaluation

A

report on the implementation and effectiveness of the program being funded

47
Q

Four components of Program Evaluation

A
  1. applied research
  2. needs assessment
  3. formative evaluation
  4. summative evaluation
48
Q

theory

A

unified explanation for discrete observations that might otherwise be viewed as unrelated or contradictory

49
Q

Grounded Theory

A
  1. in qualitative research
  2. inductive
  3. grounded in observations
  4. evolutionary
  5. regularly revised during observations
