How many standard deviations is 16.50 from the mean?
How many standard deviations is 16.50 from the mean?
I have two data sets with the same number of values with means x1 and x2 and standard deviations of n1 and n2. How do you average means with standard deviations?
You can't average means with standard deviations. What are you trying to do with the two sets of data?
What does a z-score represent in terms of units?
standard deviations
How many standard deviations are 95 percent of measurements away from the mean?
95 percent of measurements are less than 2 standard deviations away from the mean, assuming a normal distribution.
When computing the sample variance the sum of squared deviations about the mean is used for what reason?
You want some measure of how the observations are spread about the mean. If you used the deviations their sum would be zero which would provide no useful information. You could use absolute deviations instead. The sum of squared deviations turns out to have some useful statistical properties including a relatively simple way of calculating it. For example, the Gaussian (or Normal) distribution is completely defined by its mean and variance.
What is postural deviation in physical education?
Kiphosis and Lordosis are two postural deviations when talking about physical education or the human body in general. Your question is very open ended and needs to be asked more directly.
What are postural defects?

How would you identify and report deviations and what is the significance of deviations?
identify and report deviations
Another word for postural?

What is the sum of the deviations from the mean?
The sum of standard deviations from the mean is the error.
Describe ideal postural alignment and common pathological postures to a client who is commencing an exercise program?
Ideal postural alignment can be determined by drawing an imaginary line connecting the ear lobe, anterior shoulder, lumbar spine, posterior hip, anterior knee and anterior ankle. Deviations from this vertical may highlight postural problems. Common pathological postures are: 1. Kyphosis 2. Increased/Decreased Kyphosis 3. Lordosis 4. Scoliosis 5. Rounded shoulders 6. Anterior pelvic tilt 7. Posterior pelvic tilt 8. Genu Varum 9. Genu Valgum

What is postural instability?
Postural instability: loss of ability to maintain upright posture caused by slow or absent righting reflexes
When was Deviations Project created?
Deviations Project was created on 2007-02-20.
The sum of the deviations about the mean always equals what?
The sum of total deviations about the mean is the total variance. * * * * * No it is not - that is the sum of their SQUARES. The sum of the deviations is always zero.
