What is the variance of temperature between day and night in the desert?

Suppose the standard deviation is 36 Find the variance?
Variance is 362 or 1296.

The variance is: 3.96
Find the variance of these numbers 77 93 96 96 99?
The variance is: 76.7
How do you find the z score of 12.5?
To find the Z score from the random variable you need the mean and variance of the rv.To find the Z score from the random variable you need the mean and variance of the rv.To find the Z score from the random variable you need the mean and variance of the rv.To find the Z score from the random variable you need the mean and variance of the rv.
Is variance the square root of standard deviation?
No, you have it backwards, the standard deviation is the square root of the variance, so the variance is the standard deviation squared. Usually you find the variance first, as it is the average sum of squares of the distribution, and then find the standard deviation by squaring it.
Suppose the variance is 64 Find the standard deviation?
Standard deviation is the square root of the variance; so if the variance is 64, the std dev is 8.
How do you find range when all you have is the variance?
You cannot.
How do you do variance?
you have to first find the Mean then subtract each of the results from the mean and then square them. then you divide by the total amount of results and that gives you the variance. If you square root the variance you will get the standard deviation
What is difference between the amount budgeted and the actual amount is called?
Difference between actual amount and budgeted amount is called "Variance" and variance analysis is done to find out the reasons for variance
How do you work out variance?
you have to first find the Mean then subtract each of the results from the mean and then square them. then you divide by the total amount of results and that gives you the variance. If you square root the variance you will get the standard deviation
How to find the variance of 36 percent of voters favor a given ballot for groups of 30 voters find the variance for the nunmber who favor the measure?
If you assume a binomial distribution, the variance is n*p*(1-p) where n is the number of voters = 30 p is the probability of support = 0.36 So variance = 30*0.36*0.64 = 6.912
The median and variance of a distribution are 35 2.56 respectively find median and variance if each observation is multiplied vy 3?
If each observation is multiplied by 3, the median is 105 and the variance is 9 times 2.56 = 23.04.
