Using two Z tables makes life easier such that based on whether you want the know the area from the mean for a positive value or a negative value, you can use the respective Z score table. If you want to know the area between the mean and a negative value you will use the first table (1.1) shown above which is the left-hand/negative Z-table.

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.
5 lis 2020 · 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. Any normal distribution can be standardized by converting its values into z scores.
A z-table, also called standard normal table, is a table used to find the percentage of values below a given z-score in a standard normal distribution. A z-score, also known as standard score, indicates how many standard deviations away a data point is above (or below) the mean.
When we convert a normally distributed variable into a z-score, we can use the Z-score table and find the proportion of area under the normal curve. The total area under the standard normal curve is equal to 1.

16 wrz 2022 · 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. Any normal distribution can be standardised by converting its values into z -scores. Z -scores tell you how many standard deviations from the mean each value lies.
