What else can I help you with?
I am given 9 15 28 10 and 8 what is the mean absolute deviation for this data?
The mean deviation or absolute mean deviation is the sum of the differences between data values and the mean, divided by the count. In this case the MAD is 6.
IQ test scores are normally distributed with a mean of 100 and a standard deviation of 15 An individual's IQ score is found to be 110 Find the z-score corresponding to this value?
mean= 100 standard deviation= 15 value or x or n = 110 the formula to find the z-value = (value - mean)/standard deviation so, z = 110-100/15 = .6666666 = .6667
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 is the variance and standard deviation of 4 7 2 7 9 10 15?
Variance = 17.9047619 Standard Deviation = 4.23140188
A simple random sample of 64 observations was taken from a large population The sample mean and the standard deviation were determined to be 320 and 120 respectively The standard error of the mean you?
15
Which is more consistency arthematice mean is 110 and standard deviation is 25 and arthematic mean is 90 and standard deviation is 15?
The standard deviation is a number that tells you how scattered the data are centered about the arithmetic mean. The mean tells you nothing about the consistency of the data. The lower standard deviation dataset is less scattered and can be regarded as more consistent.
Which is better a score of 92 on a test with a mean of 71 and a standard deviation of 15 or a score of 688 on a test with a mean of 493 and a standard deviation of 150?
score of 92
The weights of nine men have a mean of 175 and a standard deviation of 15 what is the standard error of the mean?
(15/sqroot(9))=5 So it is 5
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.

What is the standard deviation for 11 13 15 16 20 21?
3.898717738 is the standard deviation.
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 is the standard deviation of kids in a family in America in any or all of the last 5 years?
I would say in America the mean IQ is about 60 and the standard deviation is about 15, this is about true for all ages.
What is the variance and standard deviation of 4 7 2 7 9 10 15?
Variance = 17.9047619 Standard Deviation = 4.23140188
What is the z value for an IQ score of 100?
IQ is distributed normally, with a mean of 100 and a standard deviation of 15. The z-score of 100 is therefore:(value-mean)*standard deviation= (100-100)*15= 0More generally, a raw score that is equivalent to the mean of a normal distribution will always have a z-score of 0.
