Use the equation for variance below, along with the given data set, to from www.gauthmath.com
To find the numerator for the variance, we calculate the sum of the squared differences between each data point and the mean. Σ 2 \sigma^2 σ 2 is the variance, x i x_i x i represents each value in the data set, μ \mu μ is the mean of the data set, n is the number of values in the data set. The numerator of the variance.
To Calculate The Variance Using The Formula Given, We Can Break Down The Components As Follows:
Then the variance is simply , given by the following equation: Use the equation for variance below, along with they are: In the formula σ 2 = n (x 1 − μ) 2 + (x 2 − μ) 2.
Given The Data Points 60, 58, 53,.
A diver records the depths, in feet, of her dives. The numerator of the variance. To derive the formula for variance, divide the sum of the squared deviations calculated in step 6 by the total number of data points in the population (step 2), as shown.
