It is mean + 2*standard deviation.
It is 10.
The standard deviation of the population. the standard deviation of the population.
The standard deviation is 0.
The mean alone is not enough to provide an answer.
If the standard deviation of 10 scores is zero, then all scores are the same.
[10, 10, 10, 10, 10, 10, 10] has a mean of 10 and a standard deviation of zero.
It is mean + 2*standard deviation.
Mean: 26.33 Median: 29.5 Mode: 10, 35 Standard Deviation: 14.1515 Standard Error: 5.7773
Since the standard deviation is zero, the scores are all the same. And, since their mean is 10, they must all be 10.
Standard Deviation = (principal value of) the square root of Variance. So SD = 10.
Variance = 17.9047619 Standard Deviation = 4.23140188
The deviation is 1694.
The standard deviation is the standard deviation! Its calculation requires no assumption.
It is 10.
The standard deviation of the population. the standard deviation of the population.
The standard deviation is 0.
