To find the standard deviation of a set of numbers, you first need to calculate the variance. In this case, the set of numbers is {80, 0.8, 0.2}. To calculate the variance, you need to find the mean of the set first. The mean is (80 + 0.8 + 0.2) / 3 = 27. To find the variance, you need to calculate the sum of the squared differences between each number and the mean, then divide by the number of elements in the set. Finally, the standard deviation is the square root of the variance.
What else can I help you with?
What are the assumptions of standard deviation?
The standard deviation is the standard deviation! Its calculation requires no assumption.
What does the sample standard deviation best estimate?
The standard deviation of the population. the standard deviation of the population.
What is standard deviation of 155.45?
The standard deviation is 0.
If quartile deviation is 24. find mean deviation and standard deviation?
Information is not sufficient to find mean deviation and standard deviation.
What is the relationship between standard deviation and variance?
Standard deviation is the square root of the variance.
What is the standard deviation of a standard normal distribution?
The standard deviation in a standard normal distribution is 1.
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.
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.
Why do we need the standard deviation?
The standard deviation is a measure of the spread of data.

Can a standard deviation of a sample be equal to a standard deviation of a population?
Yes
What is standard deviation used for?
Standard deviation is a measure of the spread of data.
