Variance Formula Math Spm

As the variance of a sample needs to be calculated thus, the formula for sample variance is used. Additional mathematics form 4 (formula) fatini adnan. 14/10/2013 · 7.3 variance and standard deviation. The formula for sample variance is similar to that for a population with some adjustments to account for the differences in data types: Variance means to find the expected difference of deviation from actual value. The variance is a measure of the mean for the square of the deviations from the mean.

N = 6, mean = (43 + 65 + 52 + 70 + 48 + 57) / 6 = 55.833 m.

Before learning the variance formula, let us recall what is variance.

Variance (σ 2) is the squared variation of values (x i) of a random variable (x) from its mean (μ). The variance formula is different for a population and a sample. N = 6, mean = (43 + 65 + 52 + 70 + 48 + 57) / 6 = 55.833 m.
