Standard Deviation tells you how spread out the set of scores are with respects to the mean. It measures the variability of the data. A small standard deviation implies that the data is close to the mean/average (+ or - a small range); the larger the standard deviation the more dispersed the data is from the mean.

What is the standard deviation of these four scores 2 4 3 7?
Standard deviation is the square root of the mean. The mean for this set is (2 + 4 + 3 + 7)/4 = 16/4 = 4; the square root of this is 2.
What are the units of measurement of standard deviation?
Standard deviation has the same unit as the data set unit.
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.
Given that the variance for a data set is 1.20 what is the standard deviation?
1.10
Is variance square of standard deviation?
Yes, the variance of a data set is the square of the standard deviation (sigma) of the set. This means that the variance is always a positive number, even though the data might have a negative sigma value.
What is the range and standard deviation when the variance for a set of scores is 25?
5
If each score in a set of scores were increased by 6 points how would this affect the mean and the standard deviation?
This would increase the mean by 6 points but would not change the standard deviation.
What is the standard deviation of these four scores 2 4 3 7?
Standard deviation is the square root of the mean. The mean for this set is (2 + 4 + 3 + 7)/4 = 16/4 = 4; the square root of this is 2.
What are the units of measurement of standard deviation?
Standard deviation has the same unit as the data set unit.
What is the standard deviation of the data set given below?
A single number, such as 478912, always has a standard deviation of 0.
Does the size of the standard deviation of a data set depend on where the center is?
Yes it does. The center, which is the mean, affects the standard deviation in a potisive way. The higher the mean is, the bigger the standard deviation.
What does one standard deviation mean?
Standard deviation is a measure of variation from the mean of a data set. 1 standard deviation from the mean (which is usually + and - from mean) contains 68% of the data.
What is deviation in statistics?
Deviation, actually called "standard deviation" is, in a set of numbers, the average distance a number in that set is away from the mean, or average, number.
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.
What is he standard deviation of the data set given below 478912?
A single number, such as 478912, always has a standard deviation of 0.
How do you use standard deviation?
Standard deviation is a measure of how spread out a set of numbers are from each other. It has a variety of uses in statistics.
What is the standard deviation of the following data set rounded to the nearest tenth 6040354539?
The standard deviation of a single number, as in this question, is 0.
