If the standard deviation of 10 scores is zero, then all scores are the same.
Since the standard deviation is zero, the scores are all the same. And, since their mean is 10, they must all be 10.
T scores are also standardized norm scores, where the mean value is 50 and standard deviation value is 10, in contrast to Z scores where mean value is "0" and standard deviation value is 1. -Rama Reddy Karri
Variance = 17.9047619 Standard Deviation = 4.23140188
The deviation is 1694.
If the standard deviation of 10 scores is zero, then all scores are the same.
All the scores are equal
Since the standard deviation is zero, the scores are all the same. And, since their mean is 10, they must all be 10.
T-scores have a mean of 50 and a standard deviation of 10. These values are fixed and do not change regardless of the distribution of T-scores.
T scores are also standardized norm scores, where the mean value is 50 and standard deviation value is 10, in contrast to Z scores where mean value is "0" and standard deviation value is 1. -Rama Reddy Karri
[10, 10, 10, 10, 10, 10, 10] has a mean of 10 and a standard deviation of zero.
Mean: 26.33 Median: 29.5 Mode: 10, 35 Standard Deviation: 14.1515 Standard Error: 5.7773
Standard Deviation = (principal value of) the square root of Variance. So SD = 10.
Variance = 17.9047619 Standard Deviation = 4.23140188
The deviation is 1694.
Within 1 stdev of the mean - between 40 and 60.
It is 10.
