Find mean (x)and median (m) of your data. 2. Find the variance (s2) and standard deviation (s) of your data. 3. Compute the intervals (x-s,x+s), (x -2s, x + 2s), and (x -3s, x + 3s), and find the percentage of values that fall in each of the above intervals. Does your data satisfy the Empirical rule? 4. Find the lower quartile, the upper quartile, and the interquartile range. 5. Compute the values of the inner and the outer fences of your data set and use their values to determine if your data set has any outliers.
