What is the variance of this data set? o? = (2.1546)? g² = 4.6423 Given that the standard deviation is 2.1546 and it is the square root of the variance, the value of the variance is 4.6423. 6. Are there any outliers with this data set? (Outliers refer to data points that lie beyond 3 standard deviation from the mean). There are no outliers with this data set since all values in the data set do not go beyond the three standard deviations from the mean.
