SD = 150. z = 230 ÷ 150 = 1.53. The z score for a value of 1380 is 1.53. That means 1380 is 1.53 standard deviations from the mean of your distribution. Next, we can find the probability of this score using a z table.

Web$\begingroup$ The SD is the square root of the variance, which is just the mean squared value (adjusted by a multiple of the squared mean, which you already know how to update). Therefore, the same methods used to compute a running mean can be applied without any fundamental change to compute a running variance. In fact, much more sophisticated …
