Multiply this number by 100 to get percentages. Then go to the x axis to find the second decimal number (0.07 in this case). If you remember, the formula of the z score is (x mean) / standard deviation. Find the first two digits on the y axis (0.6 in our example). Now, it is finally the time to determine the z score. calculate a z-score corresponding to his actual test score) and use a z-table to determine how well he did on the test relative to his peers. Now we would like to know how well George performed compared to his peers. Any normal distribution can be standardized by converting its values into z-scores. Finding a corresponding probability is fairly easy. The average score was 600 () and the standard deviation was 150 (). The standard normal distribution, also called the z-distribution, is a special normal distribution where the mean is 0 and the standard deviation is 1. For George’s example we need to use the 2nd table as his test result corresponds to a positive z-score of 0.67.
#Standard normal table z score calculator how to
how to find standard score for any raw value of X in the normal distribution. If a z-score calculation yields a negative standardized score refer to the 1st table, when positive used the 2nd table. Z-score calculator, p-value from z-table, left tail, right tail, two tail. If you noticed there are two z-tables with negative and positive values. If you want to compute the probability of the event. The standard normal distribution probabilities play a crucial role in the calculation of all normal distribution probabilities. standard normal distribution table) comes handy. The answer is simple, the standard normal distribution is the normal distribution when the population mean.

Therefore: Z score = (700-600) / 150 = 0.67 Now, in order to figure out how well George did on the test we need to determine the percentage of his peers who go higher and lower scores.
