Q

What are the four research paradigms

A

1) POSITIVISTS (Truth is known) cause
2) POST POSITIVISTS (Semi objective. We might know truth) correlation
3) CONSTRUCTIONIST/CONSTRUCTIVIST (Subjective. Truth is situationally based in subject to interpretation)
4) TRSNSFORMATIVE: research that is politically savvy an attempt to address systemic and societal issues across all peoples.

Q

 in terms of validity
Evidence based on content means

A

How well the continent is represented by the sample used in the instrument.

A test about the Olympics would ask questions about sports not submarines

Q

Evidence based on the response process means
(Validity)

A

How will the scores of an instrument compare to observers ratings of the individual completing the instrument. Do they match.

Q

What is evidence based on internal structure

A

A statistical analysis of items in the instrument

Does the measurement show that the IV is affecting the DV

 The degree to which we can accurately infer that X caused or is related to Y

Q

Construct validity is:

A

The accumulation of evidence to support the interpretation of what a measure reflects

Is the ability of an instrument to accurately measure a construct. Such as “a math test to measure sign language ability.“ Has no construct validity

Q

What is quasi experimental quantitative research

A

Direct manipulation of the independent variable by the researcher. Intact groups used as subjects.
(Example: you can’t break up to fourth grade classes for random sampling if you plan on using one has a control group)

25
What is historical quantitative research
A description of the past events A meta-analysis of studies
26
What is a meta-analysis of studies
Examination of data from several Independent studies On the same subject to look for overall trends
27
The positivist research paradigm holds that:
Truth is known. Hypotheses are generated before the study begins
28
The post positive research paradigm says that:
We might know the truth. It is semi objective. Other factors and forces my exert influences on the variables. “The results likely suggest…” “Correlation”
29
constructionist or constructivist research paradigm holds that
Truth is subjective. Data are collected before the hypothesis. The researcher is the instrument and is an essential facet and influence or in the study
30
The transformative research paradigm is
Research that is politically savvy and attempts to address systemic and societal issues across all peoples
31
Chapter 1 of a research proposal provides what:
Justification and rationale for the study
32
Chapter 2 of a research proposal provides what?
The literature review
33
Chapter 3 of a research proposal provides what?
The methodology of the proposed study.
34
What are the three types of research questions?
Descriptive – describing a phenomenon or event Difference – looking for differences between two groups or within individual participants Relationship – explore the degree that which two variables are related
35
What is sampling bias
when a sample is Collected in such a way that some members of the population have a lower or higher chance of being picked than others
36
What is motivational bias
A conscious or unconscious distortion motivated by one’s incentives or motivations
37
What is impression management
When people aren’t honest about their conduct. An example would be number of sex partners or “I only had two drinks“
38
What is the purpose of research
One to improve knowledge 2) To improve efficiency and effectiveness 3) To determine what works 4) To inform policy 5) To make data driven decisions
39
Random sampling is:
All members of a population have an equal probability of being selected
40
Convenience sampling is:
Using participants who are willing able and available. But may not be representative of the greater population
41
Snowball sampling is:
when participants in a study are asked to suggest and refer other participants.
42
Simple random sampling is:
All members have an equal chance of being selected
43
Systematic random sampling is:
Random selection of individuals at specified intervals - example every 10th person
44
What is stratified random sampling
Dividing populations into strata to maintain proportionality. Example balancing males and females in a study
45
What is multi stage cluster sampling
Selection of groups of people not individuals which will occur in two or more data collection intervals. For example using three middle schools across the country then doing for high schools
46
What is purposive sampling
 Deliberate selection of Specified individuals to participate in the study
47
When choosing a sample what is “matching”
ensuring that members of a sample have similar characteristics so that the independent variable can be tested against the dependent variable 
48
When choosing a sample what is blocking
Grouping so that the sample is homogeneous . Pretty much “matching” for groups
49
What is statical power
The likelihood of a test detecting an effect when there actually is one
50
What are the types of qualitative studies
Ethnomethodology Phenomenology Grounded Theory Historical Case study Action research Narrative
51
What is Ethnomethodology and give an example
Studies how social order is produced In and through the process of social interaction Examines the ordinary and “norms” of some thing Example: how middle school students define their social groups
52
In QLT research what is a case study and give an example
Examines the ideal or outliers Example: serial killer Aileen Wuornos opinions on men Or How Michael Jordan plays basketball
53
What is phenomenology
Phenomenology Is the philosophy of “experience” Therefore Phenomenological Study would be a study of someone’s experience Example: exploring the lived experiences of women undergoing breast biopsy
54
What is “grounded theory” as a type of qualitative research?
Construction of a hypothesis through collecting data. In other words… It’s pretty much the opposite of quantitative research. Example: why are employers frustrated by their job? The process would be HR gathers data comes up with themes about what the employee say and comes up with a theory about why the work place is frustrating. 
55
Is action research qualitative or quantitative?
Qualitative
56
Is historical research qualitative or quantitative
Qualitative
57
What is a moderating variable
A moderating variable is one that can strengthen, diminish, negate, or otherwise alter the relationship between the independent and dependent variables Example: gender being the moderate variable , Hours spent exercising is the independent variable, resting heart rate is the dependent variable
58
What is a mediating or an intervening variable
 A theoretical variable that The researcher uses To explain a cause or connection between the independent and dependent variable Stands between the IV and the DV
59
What is statistical precision
As sample size increases statistical precision increases
60
What is effect size
A measure of how much a meaningful difference exist between groups being compared 
61
What are performance measures
Typically test in which the objective is for the test take her to obtain his or her best score
62
What are attitudinal measures
Measures attitude or beliefs. Typically use inventories to try and measure a typical score
