Finding z score for a percentile
WebThe minimum percentile required left to the required z-score is 80% i.e. (100-20)%. As we know, invNorm takes the probability of values less than the required z-score.So, we will check the 0.80 probability in order to calculate the top 20% of the distribution. WebA z-score measures exactly how many standard deviations above or below the mean a data point is. Here's the formula for calculating a z-score: z=\dfrac {\text {data point}-\text {mean}} {\text {standard deviation}} z = standard deviationdata point − mean. Here's the …
