define population
larger group to which results are generalized
41
define sample
subgroup of populationfor estimating characteristics of a population
42
what is the dilemma with inclusion and exclusion criteria
strict criteria can limit generalizability and clinical relevance
43
describe probability sampling
randomization is involved at some point
44
describe non-probabilty sampling
no randomization, questions ability to generalize to population
45
types of probability sampling
simple random sampling systematic sampling stratified sampling cluster sampling
46
describe simple random sampling
each member of population is equally likely to be selected requires entire population to be known
47
describe systematic sampling
chosen from list/ every nth name,
48
describe stratified sampling
random sampling from subgroups
49
describe cluster sampling
divide population into clusters, usually geographic and randomly sample from them
50
types of non-probability sample
convenience sampling Quota sampling purposive sampling snowball sampling
51
describe convenience sampling
people chosen based on their availability recruitedbased on availibility
52
describe quota sampling
equivalent to statified sampling- sampling from subgroups
53
purposive sampling
sample selected for purpose
54
which type of sampling technique is commonly used in qualitative studies
purposive sampling
55
describe snowball sampling
ask recruited members to recommend others
56
name the requirements for internal validity
temporal precedence- outcome changes after change in treatment co-variation of cause and effect no plausible alternative explainations
57
single group threats have
no control group
58
multiple group threats have
multiple groups that aren't treated equally
59
social threats are based on
human behavior
60
list the types of single group threats
history maturation testing instrumentation mortality/attrition regression to mean
61
how does history affect single group threats
events unrelated to study influence outcome
62
how does maturation affect single group threats
changes in outcome due to the passing of time
63
how does testing affect single group threats
may improve scores based on repeating tests
64
instrumentation as a single group threat
change in instrumentation things not working right
65
attrition as a single group threat
subject dies or drops out
66
regressiong to mean as a single group threat
groups are selected based on extreme scores from single test
67
multiple group threats include what
history maturation testing instrumentation regression
68
history as a multiple group threat
groups have different experiences between pre and post test
69
maturation as a multiple group threat
naturally change at different rates
70
multiple group threats are based on what
differences between groups that affect cause/effect relationship influenced by subject selection
71
testing as a multiple group threat
pre-test affects groups differently
72
instrumentation as a multiple group threat
inconsistant instrumentation between groups
73
regression as a multiple gorup threat

how can you help avoid social threats
blind subjects and investigator
76
how can you help avoid social threats
blind subjects and investigator
77

members of control group receive intervention
79
co-intervention as a social threat
subjects recieve another form of treatment
80

intervention is not applied consistantly
81

ppls behavior and performance improve when they are receiving attnention
83
what is the reverse hawthorne effect
ppls behavior and performance decline if they are not recieving equal attention or care
84
what are the external validity threats
people place time detection bias recall bias
85
people as an external validity threat
sample doesn't represent population due to criteria

place as an external validity threat
the setting is not real enough
87
ecological validity
study atmosphere is similar to real life
