A goniometer that is not calibrated properly will give you______. This is know as a _______.

• consistently wrong answers; systematic error

• consistently wrong answers; random error

• valid answers; systematic error

• valid answers; random error

Attitude, time of day, and environment all contribute to_________

• systematic error

• random error

• absolute error

• relative error

You want to avoid committing a systematic error. Which of the following is the best way to prevent this?

• Run the experiment same time everyday

• keep the environment the same everyday

• Train the testers

• ensure participants are calm before giving the test

What reliability value is considered adequate for most clinical tests?

• .55

• .65

• .75

• .85

Two scores correlate highly with each other, but show poor agreement. What would these scores look like?

• r=50; ICC=.95

• r=.90; ICC=.75

• r=.99; ICC=.33

• r=.29; ICC=.30

Which of the following would negatively effect inter-rater reliability the MOST?

• Discussion between raters comparing measurements

• both raters undergoing the same training

• raters performing measurements independent of each other

Alternate form reliability is BEST used when comparing:

• range of motion

• manual muscle testing

• self-report measures

• walking speed tests

Sensitivity is defined as:

• find a + when + exists

• find a - when - exists

A highly specific test, when ________, rules ___ the condition.

• positive; in

• positive; out

• negative; in

a low pre-test probability and a high +LR will result in a:
