Variance Function Excel

Variance Function Excel - It assesses the average squared difference between data values and the mean. Subtract the mean and square the result (the squared difference). The units of variance are the square of the units measured in the data set. The variance is the square of the standard deviation. Variance is a measure of variability in statistics. Then calculate the average of those squared. It helps us determine how far each number in the set is from the mean or average, and from every other number in the set. It helps us understand the spread or dispersion of data points. The red population has mean 100 and variance 100 (sd=10) while the blue population has mean 100 and variance 2500 (sd=50) where sd stands for standard deviation. Variance is a measure of how spread out a data set is, and we calculate it by finding the average of each data point's squared difference from the mean.
