Q

nonequivalent control group pretest-posttest design

A

a pretest posttest quasi experimental design (the groups aren’t randomly assigned, but you got baseline data on both to check that they’re pretty equivalent)

Q

Time series design

A

It improves on the one group pretest posttest design because it’s over a longer period of time (for example you compare a whole year before and whole year after the treatment to get a better picture)

25
Homogeneity
when you're not able to use randomization, homogeneity can help. It just means the characteristics of the group members are the same in order to rule out confounding variables
26
Matching
Kind of like homogeneity except more precise. In homogeneity you say "everyone will be male." It matching you say "we'll have 2 males and 2 females in each group"
27
There are 4 kinds of validity
Statistical validity internal validity external validity construct validity
28
Internal validity
Is the IV really causing the outcome
29
External validity
Are the findings generalizable (valid in the real world)
30
A key concept for having external validity
Replication
31
Inferences from the details of the study to the higher level constructs they're supposed to represent
Construct validity
32
The nonequivalent control-group, pretest posttest design involves comparing an intervention group to a _____ ____ that was not created through randomization, and the collection of pretreatment data
comparison group
33
Non experimental research includes 2 types
descriptive | correlational
34
researchers begin with a possible cause, and then collect data about the outcomes
prospective cohort study
35
Study validity concerns the extent to which appropriate
inferences can be made
36
Target population
The entire, larger population
37
The portion of the Target Population that the research can get to
accessible population
38
Strata ___ ___ segments of a population based on a specific characteristic
mutually exclusive
39
is Convenience Sampling random or nonrandom
nonrandom
40
is Consecutive Sampling random or nonrandom
nonrandom
41
Consecutive sampling
recruit EVERYone from an accessible population over a specific amount of time or until you get a specific amount of people
42
Random Sampling basic definition
everyone in the target population has an equal chance of being selected
43
Simple Random Sampling
1. Researchers make a sample frame 2. For example is Lehman nursing students was the accessible population, then a student roster would be the sampling frame 3. Each student on the roster gets a number, and then numbers are randomly chosen
44
Sampling frame
the list of population elements | For example is Lehman nursing students was the accessible population, then a student roster would be the sampling frame
45
Stratified Random Sample
Same as simple random accept that first their a strata made and then people are taken at random from each strata
46
Systematic Sampling
- for example, select every 10th person on a list - It can be useful because sometimes it's more convenient than regular random sampling (and Systematic is considered random)
47
Researchers can estimate how large their samples should be using a
power analysis
48
When the researcher interviews the participant the instrument is called an
interview schedule
49
Likert Scale
Asks you to say the extent to which you agree with something (for example "5-strongly agree"
50
Formula for Sampling Interval
divide the population size by the sample size
51
What are nominal, ordinal, interval, and ratio
The 4 levels of measurement
52
Nominal measurement example
male = 1 and female = 2 | It's the lowest level
53
Ordinal measurement example
1 = completely dependent 2= needs assistance 3 = independent It ranks people relative to an attribute
54
Interval measurement example
similar to ordinal, but you can also specify the exact distance between people
55
Ratio measurement example
It had everything the interval measure has plus there's a Zero on the scale This allows you to say that someone who weighs 200 pounds is twice as heavy as someone who weighs 100 pounds
56
Reliability
How consistent is an instrument? | If you weighed someone twice, does the scale have the same reading each time?
57
Stability
kind of like reliability, except you're looking at how stable it is on SEPARATE occasions
58
Test-retest reliability assesses
Stability
59
Internal Consistency
Do all the questions in the instrument measure the same thing? For example, In a Depression questionnaire, there shouldn't be a question that measures Anger
60
Validity
Does the instrument measure what it's supposed to
61
Known-groups technique
Groups that we expect to differ are given the instruments, and we see if the instruments did in fact catch the expected differences
62
Sensitivity
does the measure correctly identify the "case"
63
Specificity
does the measure correctly rule out the "non cases"
64
A level of measurement that involves mutually exclusive categories
nominal
65
the ranking of people based on their relative standing on an attribute
ordinal
66
indicating not only people's rank order, but also the distance between them
interval
67
the degree of consistency or accuracy with which an instrument measures an attribute
Reliability
68
refers to the extent to which all the instrument's item are measuring the same attribute
Internal consistency
69
the degree to which an instrument measures what it is supposed to measure
validity
70
concerns the sampling adequacy of the content being measured
content validity
71
Statistical significance
It means the results are not just due to chance
72
Emic perspective
insiders view. The way that the members of a culture view themselves
73
Etic perspective
outsides view of a culture
74
Ethnographers enlist the help of ___ ____ to help them understand and interpret the events and activities being observed
key informant
75
Phenomenologic researchers ask
what is the ESSENCE of this phenomenon as experienced by these people and what does it mean
76
A key word in phenomenology
Essence
77
Constant comparison
a procedure used to create and refine concepts and categories
78
Narrative analysis
A type of quaL design | focuses on the story
79
Intuiting
remaining open to the meanings of a phenomenon according to the people who experienced it
80
Historical research
A qualitative design that relies primarily on narrative data, but can also include some quaN data
81
Historical research is usually ____
interpretive
82
quaL studies that don't fit into one of the exact categories
descriptive qualitative studies
83
Critical theory
a critique of society and envisioning new possibilities
84
Critical ethnography
attempts to raise awareness and make a social change
85
Participatory action research
Based on the idea that knowledge is power....political power
