Then, you would calculate the average price for the stock over the 20-year period. Next, you would subtract the average price from each individual year's price to get the deviation for each year. After that, you would square each of these deviations, sum them up, and divide by the number of years to get the mean square deviation. Finally, you would take the square root of the mean square deviation to get the smallest square deviation for the stock over the 20-year period. **
