The population standard deviation is 100?
It can be.
What is the standard error if the population standard deviation is 100 and the sample size is 25?
Formula for standard error (SEM) is standard deviation divided by the square root of the sample size, or s/sqrt(n). SEM = 100/sqrt25 = 100/5 = 20.
For a set of 100 observations with a mean of 46 and a standard deviation of 0 What is the value of the smallest observation in the set?
There is no actual "smallest" observation - a standard deviation of zero means that all 100 of the observations had to be 46.
What is the standard deviation for Wechsler intelligence for children?
The mean for the WISC, like the WAIS, is 100. The deviations from 100, or standard deviations, are 15.
What if a standard score is 57 and the average is 100 Is that three standard deviations below the mean or almost three?
The answer depends on what the standard deviation is.
If all students in a class scored 100 on an exam what is the standard deviation?
Standard deviation is 0.
The population standard deviation is 100?
It can be.
If a set of data has 100 points and a variance 4 then what is the standard deviation?
Standard deviation is the square root of the variance. Since you stated the variance is 4, the standard deviation is 2.
How do you convert variance of 100 to standard deviation?
Standard Deviation = (principal value of) the square root of Variance. So SD = 10.
What is the standard error if the population standard deviation is 100 and the sample size is 25?
Formula for standard error (SEM) is standard deviation divided by the square root of the sample size, or s/sqrt(n). SEM = 100/sqrt25 = 100/5 = 20.
If standard deviation 20 and sample size is 100 then standard error of mean is?
2
If the mean equals 500 and the standard deviation equals 100 Bob scored at 2nd standard deviation-what was his score?
Bob scored 300 or 700.
For a set of 100 observations with a mean of 46 and a standard deviation of 0 What is the value of the smallest observation in the set?
There is no actual "smallest" observation - a standard deviation of zero means that all 100 of the observations had to be 46.
How are Stanford-Binet intelligence scale results measured?
.The test has a mean, or average, standard score of 100 and a standard deviation of 16 (subtests have a mean of 50 and a standard deviation of 8). The standard deviation indicates how far above or below the norm the subject's score is.
What is the standard deviation for Wechsler intelligence for children?
The mean for the WISC, like the WAIS, is 100. The deviations from 100, or standard deviations, are 15.
Standard deviation is helpful in calculating?
Standard deviation is a calculation. It I used in statistical analysis of a group of data to determine the deviation (the difference) between one datum point and the average of the group.For instance, on Stanford-Binet IQ tests, the average (or, mean) score is 100, and the standard deviation is 15. 65% of people will be within a standard deviation of the mean and score between 85 and 115 (100-15 and 100+15), while 95% of people will be within 2 standard deviations (30 points) of the mean -- between 70 and 130.
Find the formula for percentage of covariance?
100 x (standard deviation/mean)
