Consider a population with a mean of 63.3 and a standard deviation of 3.82 and a score of 61.6. Calculate the z-score for 61.6 from a sample of size 19?

Mean μ = 63.3
Standard deviation σ = 3.82
Standard error σ / √ n = 3.82 / √ 19 = 0.8763681
z = (xbar - μ) / (σ / √ n )
z = (61.6-63.3) / 0.876368
z = -1.9398

What does the sample standard deviation best estimate?
The standard deviation of the population. the standard deviation of the population.
How do you calculate variance given standard deviation?
Square the standard deviation and you will have the variance.
Can a standard deviation of a sample be equal to a standard deviation of a population?
Yes
Is population standard deviation the same thing as absolute standard deviation?
No.
What is the standard deviation of 9?
You need more than one number to calculate a standard deviation, so 9 does not have a standard deviation.
How do you calculate the standard deviation of the mean using Excel?
=stdev(...) will return the N-1 weighted sample standard deviation. =stdevp(...) will return the N weighted population standard deviation.
What does the sample standard deviation best estimate?
The standard deviation of the population. the standard deviation of the population.
Why we calculate standard deviation and quartile deviation?
we calculate standard deviation to find the avg of the difference of all values from mean.,
What is the standard error of the sampling distribution equal to when you do not know the population standard deviation?
You calculate the standard error using the data.
How do you calculate variance given standard deviation?
Square the standard deviation and you will have the variance.
How does one calculate the standard error of the sample mean?
Standard error of the sample mean is calculated dividing the the sample estimate of population standard deviation ("sample standard deviation") by the square root of sample size.
Can a standard deviation of a sample be equal to a standard deviation of a population?
Yes
Is population standard deviation the same thing as absolute standard deviation?
No.
What is the standard deviation of 9?
You need more than one number to calculate a standard deviation, so 9 does not have a standard deviation.
How do you calculate standard deviation if I know variance?
Standard deviation = square root of variance.
What is the standard deviation of 157 160 161 172 165 149?
The standard deviation if the data is a sample from a population is 7.7115; if it is the population the standard deviation is 7.0396.
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.
