random shit Flashcards
what does grad f mean
people’s opinion
what is the pedro scale used for
RCT (10 is the best score)
if there is a list of authors listed who is the primary author
the first one listed
what section of the reseaerch does the purpose of the study go into
intro
what does “a priori” mean
a power analysis was done before the study and the power tells us if there is going to be a significant difference
is it easier to get a signifcant different with a 1 or 2 tail test
1
is in the questions or statement it says “proportion” of people what test would u mean
chi square
which test has different people in each group
independent t test
what is HOV and how is it tested
is an assumptions of T test an tested using levenes test in SPSS
what does it mean if the error bars on the graph is big
large amount of variability
x- axis is ____ if the mean on the graph has a 0
standardized
if there is not enough participants and the powe is to low what kind of validity is that
statistical conclusion
if a participants has a nature recovery what kind of variability is that
maturation (internal )
If a study were to pull 20 random students what kind of sample is it
simple random sample
what does true alpha calculate
inflation
if the study has 2 groups and they are tested over 3 different time periods what is this called
factorial - mixed/slit plot
is there is 3 groups and there are 4 things they could get tested on but they get treatment on one thing and measured and don’t change over time what is this called
3x4 fully independent 2 way ANOVA
if you want to increase change in a study do u want to add more items or take away more items
add
what rules in and what rules out
specificity - rule in
sensitivity - rule out
for the ROC curve what vaule do u want
low x axis value but higher y vaule
what does “intention to treat” mean
missing data was still included in the data (if people dropped out they were still included in the data)
if they give us a T value is it the calculated t value or the critical t value
ALWAYS calculated
Repeated measured ANOVA is tested …
over time
what kind of test is a mann u whitney
non parametric test ( equivalent to Independent t test)
what is a students t test
regular t test
what is welch’s t test
test that doesn’t meet HOV
What is spearman test
equivalent to personals correlation but does ordinal data
what does a 2 way ANOVA mean
2 IVs
F (2,54) what does the 2 and 54 mean
2 means the # f groups (IV)
54 means the # of people
if a study/test has 2 levels can u run a post HOC
no only for >3 level test/study
what is Cooks test
to check for outliers (ONYL AN OUTLIER IF COOKS VAULE IS >1
what is homoscedasticity
seeing if all the residuals ont he graph is constant
what is homoscedasticity
when all the residual points on the graph are constant
what does R squared mena in the model summary
what’s redicited
___ is also the effect size
r
what is the alpha for an omnibus study
.05
why do u report adjusted mean?
idk run an ANCOVA
what data has a forest plot
mete analysis
what are the CEBM levels of
1A
1B
1C
systemic review/meta
RCT
all or non
what is the CEBM levels of
2A
2B
2C
systematic review of cohort studies
individual/single cohort study
outcome research
what is teh CEBM level of
3a
3b
4
5
systematic review of case controlled studies
individual case control study
case study or seres
expert option or bench research
what is a tool to measure the quality of a study that investigates the diagnostic accuracy of a test
quads
what is the order of article components
-title
-abstract
-key words
-intro
-methods
-results
-discussion
-conclusion
where in the article is the research deign include , and primary purpose
abstract
what are the parts of the abstract
-background
-study purpose
-overview of methods (type and number of participants , primary outcome measures, protocol)
- main finding including effect size/ statistical significance
-primary conclusions
where in the articlee should review of th literature and should discuss the limitations of existing literature
intro
what are the 4 parts of the methods
participants
instrumentation
procedures
data analysis
consort floe diagram if requires in ____ manuscripts
RCT
what part of the methods shoudl the power analysis be included in
participants
what part of the methods should intervention and outcome measure and reliability/validity information be included in
intrumentation
what sections of the methods shoudl explain clearly how they handled the data , include software and version , power analysis and alpha level
data analysis
what part of the articles should strengts and limitations of the study , future research , clinical implication be included
discussion
what statistical test would u used for internal consistency
cronchas alpha
when is personals correlation th strongest
the closest to 1 or further away from 0 even if it’s negative
if the interaction is not signifcant do u run a post HOV
no
if you have hella DV what would that do to the alpha and what kind of error would it cause
inflate the alpha and type 1 error
what test do u run if you have multiple DV
MANOVA
if you have 3 2x4 ANOVAS what would u divide the alpha by ?
3 bc 3 2x4 ANOVAS so 3 different ones
if the interaction is sig do u have to worry about the main effect ?
naur
is there is small participants in a study what kind of validity is that
statistical conclusion
to increase power what would u want to happen to the cohens d
increase different between groups means and DECREASE group variability
to increase power what would u do
__ participants
___ different between groups
____ group variability
__ effect size
___ alpha level

if in a study everyone gets measure at all times it is repeated right .. so what graph is that
factorial - fully repreated
if in a study everyone gets measure at all times it is repeated right .. so what graph is that
factorial - fully recreated
if you increase the sample size what happens to teh SEM
decreases
why is something considered a split plot ANOVA
BC DIFFERENT PEOPLE IN DIFF GROUPS
what do u follow up a MANOVA w
DFA to see which DV is best at dividing the group
