LEC15: Physical Employment Standards - Test DVP and Reliability

Question 1

Possible Decisions From Test Results

Answer 1

1. True pass
2. True fail
3. False positive – “passed” but should fail
4. False negative – “failed” but should pass

Question 2

Either true pass or true fail means?

Answer 2

Minimal risk of error

Question 3

Either false positive or false negative means?

Answer 3

Much greater risk error

Question 4

Fitness component

Answer 4

1. Lab or field test
2. Difficult to simulate work task
3. Lower face validity
4. Probably better reliability
5. More precise physiological measures
6. Better data on physical fitness
7. Can reflect health status
8. Poor index of work performance
9. Less body management involved
10. Less specific training required
11. Less practice required
12. Less specialized equipment needed
13. Possibly more time efficient

Question 5

Work simulation

Answer 5

1. Discrete task or circuit
2. Able to simulate work tasks
3. Higher face validity
4. Probably worse reliability
5. Less precise physiological measures
6. Better data on physical aptitude
7. No reflection of health status
8. Better index of work performance
9. More body management involved
10. More specific training required
11. More practice required
12. More specialized equipment needed
13. Possibly less time efficient

Question 6

Literature reports that peak work capacity is reduced by about (blank) with fire protective ensembles (FPE) and SCBA. This is a burden of 20-25 kg of FPE

Answer 6

15-30%

Question 7

Fire-rescue work requires relatively (blank) rates of oxygen uptake for relatively (blank) periods of time

Answer 7

high, short

Question 8

What is systematic error?

Answer 8

A consistent or proportional difference between the observed and true values or something

i.e. improvement in one direction

Question 9

What is random error?

Answer 9

Error in measurement caused by factors which vary from one measurement to another

i.e. day to day variability
