Calculator to find out the z-score of a normal distribution, convert between z-score and probability, and find the probability between 2 z-scores.
What is z alpha/2? How to find z alpha/2 the easy way (without a z-table), plus how to look up them up in a z-table. Statistics made easy!
The z score calculator can be used to derive a z statistic from a raw score and known or estimated distribution mean and standard deviation. If the variance is known instead, then the standard deviation is simply its square root.
Finding z α/2 Note: z α/2 is a z-score corresponding to right-tailed area of α/2.
4 Οκτ 2019 · Math. Critical Value. Calculate Critical Z Value. Enter a probability value between zero and one to calculate critical value. Critical values determine what probability a particular variable will have when a sampling distribution is normal or close to normal. Formula: Probability (p): p = 1 - α/2.
