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.
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.
What is the standard deviation for Woodcock-Johnson III Tests of achievement?
The standard deviation for the Woodcock-Johnson III Tests of Achievement is typically set at 15. This is consistent with many standardized tests, which use a mean of 100 and a standard deviation of 15 to represent scores on a normal distribution. This allows for the interpretation of individual test scores in relation to the broader population.
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.
How is better to calculate your IQ with the basis of deviation 15 or with the basis of deviation 24?
deviation 15 is better
What is the range of standard deviation of 18 15 12 13 17 14 19 20 8?
The range is 12 and the standard deviation is 3.822448314.
What is the Calculated Standard Deviation In The Following Data 13 12 9 15 11 16 17 8 12 7 12?
It is 3.045
What is a population standard deviation of 2 6 15 9 11 22 1 4 8 19?
7.087547766 is the standard deviation for those figures.
What is the mean absolute deviation for 12 9 12 13 15 8 11 14 10 and 16?
The mean absolute deviation is 2
What is the average IQ for a 11 year old?
IQ is based on an average of 100 and a standard deviation of 15 for any group
What is the variance and standard deviation of 4 7 2 7 9 10 15?
Variance = 17.9047619 Standard Deviation = 4.23140188
The standard deviation of a distribution is 5 if you mutiply each score by 3 what would the new standard deviation be?
It would be 3*5 = 15.
What is the standard deviation of the normal IQ curve?
It is 15 points.
What does it mean if the standard deviation is equal to the mean?
A large standard deviation indicates that the distribution is heavily weighted far from the mean. Take the following example: {1,1,1,1,1,19,19,19,19,19} Mean is 10 and StDev = 9.49 Now look at this data set: {5, 6, 7, 8, 9, 11, 12, 13, 14, 15} Mean is still 10, but StDev = 3.5
What is a good standard deviation for a stock?
A good standard deviation for a stock is typically around 15-20. This indicates moderate volatility in the stock's price movements.

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
