The standard deviation is the standard deviation! Its calculation requires no assumption.

The cumulative probability up to the mean plus 1 standard deviation for a Normal distribution - not any distribution - is 84%. The reference is any table (or on-line version) of z-scores for the standard normal distribution.

A z-score cannot help calculate standard deviation. In fact the very point of z-scores is to remove any contribution from the mean or standard deviation.

It's used in determining how far from the standard (average) a certain item or data point happen to be. (Ie, one standard deviation; two standard deviations, etc.)

The standard deviation of the population. the standard deviation of the population.

The answer depends on the value of the new point. If the new value is near the mean then the new standard deviation (SD) will be smaller, if it is far away, the new SD will be larger.

Information is not sufficient to find mean deviation and standard deviation.

The standard deviation in a standard normal distribution is 1.

Standard error of the mean (SEM) and standard deviation of the mean is the same thing. However, standard deviation is not the same as the SEM. To obtain SEM from the standard deviation, divide the standard deviation by the square root of the sample size.

The term angle of deviation is used in reference to a prism.

You need more than one number to calculate a standard deviation, so 9 does not have a standard deviation.

Exactly as in the question: standard deviation!

Standard deviation is how much a group deviates from the whole. In order to calculate standard deviation, you must know the mean.

The square of the standard deviation is called the variance. That is because the standard deviation is defined as the square root of the variance.
