How can you make a fitness test more valid?

For a test to be valid it must ‘hit the bull’s-eye. ‘ For instance, if I wanted to measure aerobic running performance then a measure of someone’s fifty metre swim time would have poor validity, whereas a measure of the time it took for them to run five kilometres would be much more valid.

How do you increase measurement errors?

Ways to Reduce Measurement Error

1. Double check all measurements for accuracy.
2. Double check your formulas are correct.
3. Make sure observers and measurement takers are well trained.
4. Make the measurement with the instrument that has the highest precision.
5. Take the measurements under controlled conditions.

One of these is called Random Error. An error is considered random if the value of what is being measured sometimes goes up or sometimes goes down. A very simple example is our blood pressure. Even if someone is healthy, it is normal that their blood pressure does not remain exactly the same every time it is measured.

What are examples of systematic errors?

Systematic errors primarily influence a measurement’s accuracy. Typical causes of systematic error include observational error, imperfect instrument calibration, and environmental interference.
