what should the title tell you
who and what
what is the order of authorship
first author
last author/senior author
second author
middle author
which author is Usually, an experienced investigator who partners with first author in interpretation, analysis, and writing
last author
the conflict of interest is usually found where
1st page in small fonts
how mnay words is the abstract
150 words or less
what does the abstract address
only the primary purpose and none of the seconding findings
a prsopective non blinded randomized clinical trial is what type of evidence
1b
the introduction ends with
therefore the purpose of this study is to
what is a null hypothesis
there will be no difference between x and y
do people write nnull hypthesis
no
where should alternative hypthesis be found
in the journals
what are the methods (in order0
Participants
Instrumentation
Procedures
Data analysis
how mnay subsections are there in methods
4
there should be a clear …. in participants
inclusion/exclusion criteria
instrumentation may also be broken into
intervention and outcome measurments
ex of a intervention
specific type of exercise proticol used
ex of outcome measurements
2 mintue walk test
procedures much be
reproducible (decribed from start to finisih)
the data analysis should explain
how they will handle the data frim the beginning
a significant result will have a p value less than
.5
what % is there that their results will be wrong just due to chance
5
what is the independent variable
the variable that is manipulated
what is the dependent variable
variable that is measured
the mean is what
the average
the median is the
middle value
the mode is the
most common
the greater the variability
the lower the chances of finding a significant difference
the range is the
difference between the minimum and max values
to find the variance you have to squre the
standard deviation
the ANOVA test looks for
the main effective group
main effectivce time
what is the interaction
in the ANOVA test you dont want the error to be greater than
.5
what is the statistical abbreviation for a pearson product moment correlation
R
if r is +1.00 it means there is a
perfect positive correlation
if the r is 0.00 there is
no relationship
if the r is -1.00 there is a
perfect negative correlation
is the correlation of r= .80 it means that r ^2=
.64 r 64%
an R that is what is good in the field
.5 or better
T/F: correlation coefficient does not mean cause and effect
T
reliability means
consistency
validity means
accuracy
types of reliability
inter-tester
intra-tester
test-retest
can different rater get the same score is an examoke of what
inter-tester
can the same rater get the same score is an example of what
intra-tester
can successive measurments by an instrument be consistent? is an example of what
test-retest
can successive measurments by a patient by consistent? is na exmaple of what
test-retest
