Does the value of the standard deviation depend on the value of the mean?
The standard deviation is a measure of the spread of data about the mean. Although it is essentially a measure of the spread, the fact that it is the spread ABOUT THE MEAN that is being measured means that it does depend on the value of the mean. However, the SD is not affected by a translation of the data. What that means is that if I add any fixed number to each data point, the mean will increase by that number, but the SD will be unchanged.
The sum of a set of data divided by the number of pieces of data?
The sum of a set of data divided by the number of pieces of data is the average or mean.
What does it mean when a data set of 10 measurements has a mean of 15 and a standard deviation of 0?
It means that all of the ten numbers are 15!Standard deviation tells you how spread out the data is from the mean value. Or in other words, it tells you how far the numbers in your data are away from the mean value.If the standard deviation is a high number, it means the data is largely spread out and that there are big differences in the data. The numbers in the data would be quite far from each other. For example, if you had data like: 8, 35, 13, 47, 22, 64, this would probably mean that you'll get a high standard deviation because each of the numbers are very spread out.On the other hand, if the standard deviation is small, it tells you that the numbers in the data are quite close together and that there is only a small difference between the numbers in the data. For example, if you had data like: 19, 25, 20, 22, 23, 18, this would probably mean that you'll get a low standard deviation because each of the numbers aren't that spread outIn the scenario you've given, the standard deviation is ZERO. This means that there is no spread or variation AT ALL with the numbers in your data. This means every single number in the data is the same.Since your mean is 15 and every number in your data is the same, that means that all the ten numbers in your data have to be 15!Hope that makes sense.Jamz159
How do you find the mean of the data?
Th find the mean of a data set, you add up all the values in the data set and divide this sum by the number of data values. For example, the mean for the data set 2, 5, 6, and 7 is given as 2 plus 5 plus 6 plus 7, which is 20. You divide this sum by number of values in the data set, which is 4 to get 5 as the mean.
How does adding it subtracting a constant amount by each value in a set of data affect the mean?
When adding and subtracting a constant amount means that that amount will increase. The amount will increase dew to adding each number.
What happens to the mean of the home run data if the number of home runs for the first season is ignored?
It changes
Find the mean of the data?
The mean of a set of data is the sum of that data divided by the number of items of data.
What is the mean of 69101213 In maths?
There is not a mean of a single number. To calculate a mean, you need a data set. The mean is given by the sum of all the data, divided by the number of pieces of data.
Does the mean have to be a member of the set of data?
no. Some mean is a number from the data but some mean is completely different from its data.
What is the sum of the data divided by the number of data values?
It is the mean average of number of collected data values.
How does adding or subtracting a constant amount by each value in a set of data affect the mean?
Adding and subtracting is what increases the amount when adding each number. This is taught in high school math.

What does the math rearm mean mean?
The sum of the data divided by the number of pieces of data
The sum of a set of data divided by the number of pieces of data?
The sum of a set of data divided by the number of pieces of data is the average or mean.
What is the mean set of data 1056269111?
1056269111. The set of data contains only one number and the mean of one number is itself!
What is the mean of a number?
The mean of a number is the average of a group of numbers. To find the mean you must add up all of the numbers in a data set. Then you take that number and divide it by the number of numbers you have in the data set. This will give you the mean.
