The modulus of difference between both left & right side values is the probability of two tailed Z-score values. Therefore, the critical (rejection region) value of Z on right side is 0.9878įind the difference between left & right tail critical values of Z Similarly refer column value for -2.2 and row value for 0.05 in the positive values of standard normal distribution to find the right tail. Therefore, the critical (rejection region) value of Z on left side is 0.0418 Refer the column value for -1.7 and row value for 0.03 in the negative values of standard normal distribution to find the left tail.1.73 < Z < 2.25 is the two tailed distribution. The point where the column & row values met at 0.0016 is the probability or critical value of Z. To find the probability of z-score, refer the column value for -2.9 and row value for 0.05 in the negative values of standard normal distribution. 2.95 < Z is the left tailed distribution. The point where the row & column meets for the corresponding z-score value is the critical value of Z or the rejection area of one or two tailed z-distribution. Refer the column & row values for z-score. Z-scores generally ranges from -3.99 to 0 on the left side and 0 to 3.99 on the right side of the mean. Supply the positive & negative values of the z-score to find the rejection region at both right and left side of the mean of normal distribution.

Supply the positive or negative value of z-score to find the rejection region right or left to the mean of normal distribution respectively. Users may use this one or two tailed z-table calculator or refer the rows & columns value of standard normal distribution table to find the critical region of z-distribution.įor one one (left or right) tailed Z-test : Standard Normal Distribution Table for Z = -3.59 to 0.00

Standard Normal Distribution Table for Z = 0.00 to 3.59 It means that the negative z-score lies on left side represents the left tail & the positive score lies on right side represents right tail of the distribution. The negative & positive z-scores lies on the left & right side of the mean of standard normal distribution respectively.

This Z-table to find the critical value of Z is also available in pdf format too, users may download this table in pdf format to refer it later offline. For locating the Z e (critical value of Z) in the table quickly, users can supply the values of Z-score in the above interface. The estimated value of Z or Z-statistic (Z 0) is compared to critical value of Z from standard normal-distribution table to check if the null hypothesis in the Z-test is accepted or rejected at a specified level of significance (α).

We say that $X$ is a normal random variable with mean $\mu$ and variance $\sigma^2$.Find Critical Value of t for One or Two Tailed Z-Test Shown as $Z \sim N(0,1)$, if its PDF is given by Any set of normally distributed data can be converted to its standardized form and the desired prob. A continuous random variable $Z$ is said to be a standard normal (standard Gaussian) random variable, 6.1: USING THE STANDARDIZED NORMAL DISTRIBUTION TABLE.
