WebbIf standard deviation = 0, you can conclude that the range is [mean,mean], i.e., the random variable equals its mean, with probability one. If standard deviation > 0, the range could be as big as [ − ∞, ∞], even though it might be tighter. For instance, think of a Normal random variable with even a tiny, but positive, standard deviation. WebbThe fourth column of this table will provide the values you need to calculate the standard deviation. For each value x, multiply the square of its deviation by its probability. (Each deviation has the format x – μ). Add the values in the fourth column of the table: 0.1764 + 0.2662 + 0.0046 + 0.1458 + 0.2888 + 0.1682 = 1.05
