Phenotypic variance calculator
WebCalculate the variance. Variance is the sum of squares divided by the number of data points. The formula for variance for a population is: Variance = σ 2 = Σ ( x i − μ) 2 n The formula for variance for a sample set of data is: Variance = s 2 = Σ ( x i − x ¯) 2 n − 1 Variance Formula WebHeritability, in a general sense, is the ratio of variation due to differences between genotypes to the total phenotypic variation for a character or trait in a population. The concept …
