What is the variance of these set of numbers 11 24 7?
The variance is: 79.0
What is the variance of these set of numbers 10 30 40 50 70?
The variance is: 500.0
Is the standard deviation of the data values in a sample is 17 what is the variance of the data values?
The variance of a set of data values is the square of the standard deviation. If the standard deviation is 17, the variance can be calculated as (17^2), which equals 289. Therefore, the variance of the data values in the sample is 289.
What choices is variance of the sample shown here 353641566071?
To calculate the variance of the sample data set 353641566071, first find the mean by adding all the values together and dividing by the number of values. Then, compute the squared differences between each value and the mean, and average those squared differences to obtain the variance. The choices for variance would typically be numerical values reflecting the dispersion of the data around the mean.
How do you get a variance?
To calculate variance, first find the mean (average) of your data set. Then, subtract the mean from each data point and square the result to eliminate negative values. Next, sum these squared differences and divide by the number of data points (for population variance) or by the number of data points minus one (for sample variance). This final result is the variance, which measures the spread of the data points around the mean.

What is varience?
In statistics, variance measures how far apart a set of numbers is spread out. If the numbers are identical, the variance is zero. Variance can never be negative.

What does variance mean in mathematics?
A variance is a measure of how far a set of numbers is spread out around its mean.
Is the standard deviation of the data values in a sample is 17 what is the variance of the data values?
The variance of a set of data values is the square of the standard deviation. If the standard deviation is 17, the variance can be calculated as (17^2), which equals 289. Therefore, the variance of the data values in the sample is 289.
How do you figure the variance on a group of numbers?
To figure the variance on a group of numbers, you must first figure out the mean, which is the average of the set. Then, substract the mean from each number in the set. Square the result of those substractions, and then average the squares. You will then have the variance.
Set of 25 numbers has standard deviation 6 then it's variance is?
Square the standard deviation to obtain the variance. The variance is 62 or 36.

How do you find variance of 2 sets of numbers?
1. Find the mean (average) of each set. 2. Subtract each value from its set mean. 3. Square each difference. 4. Add the squared values for each set. The sum of the squared differences for each set is that set's variance. If you want to find standard deviation (a much more useful number in most cases), divide the variance by the number of values in the set minus 1 (n-1), and then take the square root of the result.
