When an integer is multiplied by itself, the resultant number is known as itssquare number. Basically, a square number is a number that is obtained by the product of two same numbers. In geometry, the area of a square with 'n' as the side length (where n is an integer) is the fine...

Explanation: An average is the sum of all the numbers in a set, divided by the number of numbers in that set. To figure this one out, set up a simple equation and solve for X: (12 + 19 + X) ÷ 3 = 17 You want to isolate the X, so first multiply both sides by 3. 17×3...

In statistics, variance measuresvariabilityfrom the average or mean. It is calculated by taking the differences between each number in the data set and the mean, squaring the differences to make them positive, and then dividing the sum of the squares by the number of values in the data set....
Types and Formulas Mean is the simple mathematical average of a set of two or more numbers. It can be computed using thearithmetic meanmethod, which uses the sum of the numbers in the series, and thegeometric meanmethod, which is the average of a set of products. ...
For example, the geometric mean calculation can be easily understood with simple numbers, such as 2 and 8. If you multiply 2 and 8, then take the square root (the ½ power since there are only two numbers), the answer is 4. However, when there are many numbers, it is more difficul...
