Easy to use calculator for converting a Z score to P-value using the cumulative probability density function (cumulative PDF) of the normal distribution. ➤ Convert Z to P, calculate P-value from Z-score of a normally distributed variable. Z score to p
Calculate Z-score (X, Mean, and SD) - Calculate raw score (Z, Mean and SD) - Calculate Z given probability (One Tail and 2 Tail) - Calculate area (%) under the normal distribution curve (below x, above x, to the mean) - Calculate the proportion of area between two scores (X1,...
The standard normal distribution always features the same shape of the raw score distribution. So, when you have raw scores that are normally distributed, the distribution of z scores will also be normally distributed. There is also another great use for researchers when they decide to use the ...
Let’s close this post by calculating the results for a Z test by hand! Suppose we randomly sampled subjects from an honors program. We want to determine whether their mean IQ score differs from the general population. The general population’s IQ scores are defined as having a mean of 100...
A: Z-scores can be used to identify outliers by looking for data points that are more than 3 standard deviations away from the mean. These data points are considered to be extreme values and may be due to measurement error or other factors that are not representative of the dataset as a...

Use this method to find the p-value for a two-sided z-test with critical regions in both tails. Z tests use Z-scores to determine statistical significance. Learn more aboutZ-Tests: Uses, Formula & Examples. To calculate this type of information using a z-table, do the following: ...
An interactive p-value calculator with solutions and graphs for Z-scores, T-scores, F-scores, and Chi-square scores.
of mean return is higher than 3%. Investors assume alpha of 0.05% is selected as a two-tailed test and 0.025% of the sample in each tail and alpha critical value is either 1.96 or -1.96. So if the result of the Z test is less or greater than 1.96 null hypothesis will be rejected....
Percentiles work similarly: they divide scores into 100 groups (or percentiles) so that each group contains exactly 1% of all scores (100/100). This means that if you get a score that places you in the 75th percentile for some test, 75% of other people who took that test had lower sco...
