Average value in data set
Define standard deviation?
It is a measure of the amount of variation or
dispersion of a set of values, from lowest-highest
Difference between reliability and validity?
Reliability is consistency over a set time, meaning it is trustworthy and done accurately, whereas Validity is how well the results represent what we intended to measure

+ = easy/inexpensive
consistent links to disease
- = Does not measure fatness or composition, therefore does not account for high levels of muscle mass
May be less appropriate

Strongly associated with diseases
- = Does not measure the amount or location
Difficult to measure accurately and consistently and can lead to issues with validity and reliability
Hand grip Dynamometer +/-?
+ = Easy/Inexpensive
Strongly and consistent with relation to future problems
- = Difficult to measure accurately = affects validity and reliability
Requires max effort
+/- Short physical performance battery ?
+ = Easy/Inexpensive
Performed across different settings
cut off values associated with risks
- = Requires assessor
Ceiling affect

+= Valid measurement of aerobic fitness
Inexpensive
Can measure large group
Continues to max
- = Practice/motivation can affect

Remove shoes and hair away from face.
Face away and back onto base.
Heels must be against base, with both back and bum resting against the arm

Take a deep breath in. Take 3 and find average, stand off after each.
Must be within .2
How to measure weight correctly?
Remove shoes, jewelry and empty pockets
Must be set at 0
Face forward and step on, looking straight ahead
Retrieve data once it has stopped fluctuating
3 measurements within 0.1 kg and find average.
