Therefore, the variance is the corrected SS divided by N-1. The Corrected SS is the sum of squared distances of data valueįrom the mean. The sum of the squared distances of data value from the mean divided by the Variance – The variance is a measure of variability. The larger the standardĭeviation is, the more spread out the observations are. Measures the spread of a set of observations. – Standard deviation is the square root of the variance. The mean is sensitive to extremely large or small values.į. The most widely used measure of central tendency. Mean – This is the arithmetic mean across the observations. Maximum – This is the maximum, or largest, value of the variable.Į. Minimum – This is the minimum, or smallest, value of the variable.ĭ.
The total number of observations is the sum of N and the number of missingĬ. N – This is the number of valid observations for the variable. Valid N (listwise) – This is the number of non-missing values.ī. statistics = mean stddev variance min max semean kurtosis skewness.Ī.
