What is the formula for a weighted standard deviation?
Arithmatic Mean
What is the formula for calculating variance and standard deviation?
b-a/6
Is standard deviation biased or unbiased?
Standard deviation (SD) is neither biased nor unbiased. Estimates for SD can be biased but that depends on the formula used to calculate the estimate.
What is the standard error if the population standard deviation is 100 and the sample size is 25?
Formula for standard error (SEM) is standard deviation divided by the square root of the sample size, or s/sqrt(n). SEM = 100/sqrt25 = 100/5 = 20.
Formula for z-test?
The z score is calculated from the distance of a value from the distribution center divided by the standard dev. (x-xbar)/st. dev
Difference between standard deviation and mean devition?
The mean deviation (also called the mean absolute deviation) is the mean of the absolute deviations of a set of data about the data's mean. The standard deviation sigma of a probability distribution is defined as the square root of the variance sigma^2,
What is the chemical formula for mercury in standard state?

What is the standard addition formula?
a+ b = c
What is the formula for standard deviation?
Standard deviation is a way to describe how the data is distributed around the Arithmatic Mean. It is not a simple formula to calculate, as shown in the links.
What is the Direct labor efficiency variance formula?
(actual time * standard rate) - (standard time * standard rate)
What is the formula for velocity when you know time and acceleration?
The standard formula is A = v/t With slight formula manipulation you get At = v
In math what is the formula for the commission?
