no
How do you find the average deviation from mean?
To Find Average Deviation 1. Find the average value of your measurements. 2. Find the difference between your first value and the average value. This is called the deviation. 3. Take the absolute value of this deviation. 4. Repeat steps 2 and 3 for your other values. 5. Find the average of the deviations. This is the average deviation The average deviation is an estimate of how far off the actual values are from the average value, assuming that your measuring device is accurate. You can use this as the estimated error. Sometimes it is given as a number (numerical form) or as a percentage. To Find Percent Error 1. Divide the average deviation by the average value. 2. Multiply this value by 100. 3. Add the % symbol.

What is variability of a set of numerical data?
Variability is determined by the how numbers are distributed across the set of numbers. There are several ways of measuring this the most common is standard deviation. To find standard deviation you first find the average of the set by adding them all up and dividing by the amount of numbers in the set. Then you find the square of each number in the set minus the average. You add all these values up, multiply them by 1/the number of items in the set, and take the square root. As an example the set {2,5,3,6} has much less variability as measured by the standard deviation than {2000,-1000,-500,484} even though they both have the same average. The firsts average is (2+5+3+6)/4 or 4. The standard deviation is the square root of(((2-4)^2+(5-4)^2+(3-4)^2+(6-4)^2)*1/4) or about 1.58113883. The standard deviation of the second set that has the same average as the first is the square root of (((2000-4)^2+(-1000-4)^2+(-500-4)^2+(484-4)^2)*1/4) or 1170.09059.
How do you find the middle of 2 numbers?
What you are trying to find is the average or mean. You find this by adding all the numbers in a set together and divide by the amount of numbers you added. Example: 1, 1, 2, 2, 3, 3. Find the average (mean). Add all the numbers in the set together: 1 + 1 + 2 + 2 + 3 + 3 = 12 Divide by the amount of numbers you added: You added together 6 numbers: 12 ÷ 6 = 2. Mean of {1, 1, 2, 2, 3, 3} = 2.

How To Calculate Standard Deviation?
You can calculate standard deviation by addin the numbers of data that are together and dividing that number by the amount pieces of data.THAT IS TOTALLY INCORRECT.What was answered above was the calculation for getting an (mean) average.If you take five numbers for example 1, 2, 3, 4, 5 then the (mean) average is 3.But the standard deviation between them is 1.58814 and the variance is 2.5Also the population std. deviation will be 1.41421 and the population variance will be 2.see standard-deviation.appspot.com/

What does median mean in mathematics?
It means the average of a group of numbers. For example... To find the average of the numbers 5 and 1, you would (1) add 5 and 1 and get 6, (2) divide your answer, 6, by the amount of numbers, 2 and (3) your average would be 3.

The word mean in math?
The word "mean" in math means the average of several numbers. To get the average 1. add all the numbers together 2. divide the sum of the numbers by how many numders there were. ex. 1. 1+2+3=6 2. 6/3 =2 so 2 is the mean
