Epigenetic, the product of genetic and nongenetic influences. Multifactorial, traits affected by many factors, both genetic and environmental, that enhance, halt, shape,or alter the expression of genes, resulting in a phenotype that may differ markedly from the genotype.
What is 'Standard Deviation' Standard deviation is a measure of the dispersion of a set of data from its mean. It is calculated as the square root of variance by determining the variation between each data point relative to the mean. If the data points are further from the mean, there is higher deviation within the data set.
The standard deviation is the square root of the variance, 9.43. The probability that area X will have a higher score than area Y may be calculated as follows: Area X will have a higher average score than area Y about 70% of the time.
