To find the standard deviation, you must first compute the mean for the data set.
So the answer is yes. Just have a look at the 5 steps needed to compute a standard deviation and you will see why the answer is yes.
In reality, people most often use calculators or computers to do this.
However, it is good to understand what they are doing.
1. Compute the deviation by subtracting the mean from each value.
2. Square each individual deviation.
3. Add up the squared deviations.
4. Divide by one less than the sample size.
5. Take the square root

What is not dependent on the size of a sample?
In general the mean of a truly random sample is not dependent on the size of a sample. By inference, then, so is the variance and the standard deviation.
Relation between mean and standard deviation?
Standard deviation is the variance from the mean of the data.
What is the difference between standard deviation and mean?
The mean is the average value and the standard deviation is the variation from the mean value.
Is the standard deviation the same as the mean of absolute distances from the mean?
no the standard deviation is not equal to mean of absolute distance from the mean
What is the definition of standard deviation?
Standard deviation is how much a group deviates from the whole. In order to calculate standard deviation, you must know the mean.
Is the standard deviation dependent on the mean?
Yes. Consider the definition of the standard deviation. It is the square root of the variance from the mean. As a result, it can be said that the standard deviation is dependent on the mean.
If quartile deviation is 24. find mean deviation and standard deviation?
Information is not sufficient to find mean deviation and standard deviation.
What is not dependent on the size of a sample?
In general the mean of a truly random sample is not dependent on the size of a sample. By inference, then, so is the variance and the standard deviation.
A standard normal distribution has a mean of and standard deviation of?
Mean 0, standard deviation 1.
What is the mean and standard deviation for the standard normal curve?
Mean = 0 Standard Deviation = 1
Does variance and standard deviation assume nominal data?
No. Variance and standard deviation are dependent on, but calculated irrespective of the data. You do, of course, have to have some variation, otherwise, the variance and standard deviation will be zero.
What is the difference between standard error of mean and standard deviation of means?
Standard error of the mean (SEM) and standard deviation of the mean is the same thing. However, standard deviation is not the same as the SEM. To obtain SEM from the standard deviation, divide the standard deviation by the square root of the sample size.
How is the mean related to standard deviation?
Mean and standard deviation are not related in any way.
Can standard deviation be greater than mean?
Standard deviation can be greater than the mean.
Relation between mean and standard deviation?
Standard deviation is the variance from the mean of the data.
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.
Is the standard deviation best thought of as the distance from the mean?
No. A small standard deviation with a large mean will yield points further from the mean than a large standard deviation of a small mean. Standard deviation is best thought of as spread or dispersion.
