σ = population standard deviation A z score of 2.24 means that your sample mean is 2.24 standard deviations greater than the population mean.Step 2: Find the p valueTo find the probability of your sample mean z score of 2.24 or less occurring, you use the z table to find the value at...
Normal distribution calculator finds probability, given z-score; and vice versa. Fast, easy, accurate. Online statistical table. Sample problems and solutions.
We have a calculator that calculates probabilities based on z-values for all the above situations. In addition, it also outputs all the working to get to the answer, so you know the logic of how to calculate the answer.How to Use the Standard Normal Distribution Table...
Enter the raw score, mean, and standard deviation to find the probability of getting a number above or below that score using the normal distribution calculator below. Probabilities: P(X ≤ x): P(X > x): P(X ≤ -x ∪ X ≥ x): ...
Lookup z score in this z table (same as z score table, standard normal distribution table, normal distribution table or z chart). You will also find a z score calculator right after the tables. Find a value representing the area to the left of apositive Z scorein this standard normal di...

Then, using an online calculator, a handheld graphing calculator, or the standard normal distribution table, we find the cumulative probability associated with the z-score. For this problem, we will use Stat Trek's freenormal distribution calculator. Since every standard normal distribution has a ...
The normal distribution calculator to finding the probability less than $1.5$, probability greater than $1.5$, probability less than $1$, probability greater than $1$ and probability between $1$ and $1.5$ with a mean of $0.5$ and standard deviation of $2$. For any other values, just su...
