As with the standard deviation, there are online tools that can accurately calculate the average of a set of numbers and calculate the square root of a figure. To find the average delay, take the supplier orders that took longer than average to arrive, add those figures together, and then ...
A critical value of z (Z-score) is used when the sampling distribution is normal, or close to normal. Z-scores are used when the population standard deviation is known or when you have larger sample sizes. While the z-score can also be used to calculate probability for unknown standard ...
The standard score (more commonly referred to as a z-score) is a very useful statistic because it (a) allows us to calculate the probability of a score occurring within our normal distribution and (b) enables us to compare two scores that are from different normal distributions. The ...
