5
Q

confounding/ extraneous variable

A

other factors that may impact the DV that isn’t the IV

so these need to be controlled

Q

distribution of data

A

frequency of data
histogram

17
Q

central tendincy

A

mean
median
mode

18
Q

variability

A

range
standard deviation

19
Q

characteristic of good measurement

A

concept measured is well defined
same answer when study same info
get different answers when change info
everyone knows what answer means

20
Q

observed score=

A

true score + error

21
Q

sytematic error

A

constant present
will cause bias

22
Q

random error

A

unpredictable
soroundings
instrument

23
Q

equipment errors

A

calibration
sensitivity
maintience
operation

24
Q

tester errors

A

competence
preperation
motivation
fatigue

25
procedure error
position handling stabilisation instructions
26
patient error
recovery and deteroration comprehension familisation environment fatigue pain
27
how to reduce error
repeat measure controlled use calibrated conditions know error of tool use same person to measure
28
reliability
degree measurements are free of error
29
intra rater reliability
inidivdual rater measures
30
inter rater reliability
between different measurears
31
intra-subject
changes in subject from time to time
32
test-retested reliability
assess conssitancy of measure from one time to another
33
valid
does the assessment test what it set outs to measure
34
norm reference
measurement frameworks based on the normal curve
35
criterion reference
indivdual performance is evaluated with respect to a level of achivement
36
ICC
agreement of a test between 0-1 1- perfect 0- no agreement
