What is the answer for calculate the mean and standard deviation for the subset of Fibonacci series given here 8 13 21 34 55 89 144?
49.30179172 is the standard deviation and 52 is the mean.
What is a difference between a pooled variance and a combined variance?
Pooled variance is a method for estimating variance given several different samples taken in different circumstances where the mean may vary between samples but the true variance (equivalently, precision) is assumed to remain the same. A combined variance is a method for estimating variance from several samples, given the size, mean and standard deviation of each. Mathematically, a combined variance is equal to the calculated variance of the set of the data from all samples. See links.
The population standard deviation on a given measure of aggressive behavior equals 18 and you have 25 cases available for your assessment Calculate the standard error of the mean?
3.6
What is the standard deviation of the data set given below?
A single number, such as 478912, always has a standard deviation of 0.
How do you find the mean variance and standard deviation of the binomial distribution with the given values of n and p?
In a binomial distribution, the mean (μ) is calculated using the formula μ = n * p, where n is the number of trials and p is the probability of success in each trial. The variance (σ²) is computed using the formula σ² = n * p * (1 - p). The standard deviation (σ) is the square root of the variance, calculated as σ = √(n * p * (1 - p)). These parameters help summarize the distribution's central tendency and spread.
What does the standard deviation tell us?
standard deviation is the square roots of variance, a measure of spread or variability of data . it is given by (variance)^1/2
Given that the variance for a data set is 1.20 what is the standard deviation?
1.10
What is the definition of standard deviation and variance?
The set of X1, X2, ..., XN is called X. Given that mean(X), is the sum of all X divided by N, the variance of X is mean((Xi - mean(X))2). The standard deviation of X is the square root of the variance.
How do you calculate probability given mean and standard deviation?
The mean and standard deviation do not, by themselves, provide enough information to calculate probability. You also need to know the distribution of the variable in question.
Why would someone need a standard deviation calculator?
A standard deviation calculator allows the user to find the mean spread away from the mean in a statistical environment. Most users needing to find the standard deviation are in the statistics field. Usually, the data set will be given and must be typed into the calculator. The standard deviation calculator will then give the standard deviation of the data. In order to find the variance of the data, simply square the answer.

What is the z score of x equals 108?
You need the mean and standard deviation in order to calculate the z-score. Neither are given.
What is the standard deviation of the data set given below?
A single number, such as 478912, always has a standard deviation of 0.
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 find the sample size if you are given the confidence interval and the margin of error as well as the standard deviation?
You can't. You need an estimate of p (p-hat) q-hat = 1 - p-hat variance = square of std dev sample size n= p-hat * q-hat/variance yes you can- it would be the confidence interval X standard deviation / margin of error then square the whole thing
