What is the Standard deviation of a set of data in which all the data values are the same?
ZeroDetails:The "Standard Deviation" for ungrouped data can be calculated in the following steps:all the deviations (differences) from the arithmetic mean of the set of numbers are squared;the arithmetic mean of these squares is then calculated;the square root of the mean is the standard deviationAccordingly,The arithmetic mean of set of data of equal values is the value.All the deviations will be zero and their squares will be zerosThe mean of squares is zeroThe square root of zero is zero which equals the standard deion
How do you find a mean of a set of numbers?
to find the mean of a set of numbers you have to find the total sum of the data divided by the number of addends in the data.
What is the median in a set of numbers?
to find the median in a set of numbers you have to order them from the smallest to the largest and find the middle value e.g. 2,4,3,7,1 1,2,3,4,7 the median is 3
What is the median of a set of numbers if the set of numbers is even?
To find the median of a set of values with an even number of values, place the values in ascending or descending order, find the 2 middle numbers and add them together and divide that total by 2 and that's the median.
What is the median of 50 54 62 53 53 61?
The median of a set of numbers is the middle number when they are laid out in numerical order. When there is an even amount of numbers in the sequence like this one, there are two numbers in the middle. To find out the median from these two numbers, you just need to find the average of the two numbers. As the two numbers in the middle of this set of numbers is 53 and 54, the average is 53.5. This means that the median of this set of numbers is 53.5.
Is the variance of a group of scores the same as the sum of the squared deviations or the average of the squared deviations?
Given a set of n scores, the variance is sum of the squared deviation divided by n or n-1. We divide by n for the population and n-1 for the sample.
What is the standard deviation?
The standard deviation of a set of data is a measure of the spread of the observations. It is the square root of the mean squared deviations from the mean of the data.
What is the Excel function AVEDEV?
It gets the average of the absolute deviations of a set of values from their mean. It can use numbers or references to those numbers.
What is the Standard deviation of a set of data in which all the data values are the same?

Is the number 36 squared in the set of rational numbers?
Yep, any rational number squared is also rational.
What is the Sum of deviation from the mean is?
The sum of deviations from the mean, for any set of numbers, is always zero. For this reason it is quite useless.
What is the domain of x squared plus nine?
domain = set R ,, all real numbers
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.
How do you find the maximum of a set of numbers?
The maximum of a set of numbers is the largest number in the set.
How do you find a mean of a set of numbers?
to find the mean of a set of numbers you have to find the total sum of the data divided by the number of addends in the data.
What is a set of numbers to find the sum of the numbers and then divide by the number in the set?
It is the mean average
How do find the midrange of a set of numbers?
find the mean in a set of frequency distribution
