Negative z score chart. Find values on the right of the mean in this z table. Table entries for z represent the area under the bell curve to the left of z. You can use the z score table to find a full set of less than probabilities for a wide range of z values using the z score formula.

The whole number and the first digit after the decimal point of the z score is displayed in the row and the second digit in the column of the normal distribution table. For example if a z score is equal to 2 it is 2 standard deviations below the mean. Negative scores in the z table correspond to the values which are less than the mean.

Some people prefer to interpret results by looking at the standard normal distribution chart and displaying their values there. A positive z score has a value that is above or to the right of the mean of the standard normal distribution. The z score can be calculated by subtracting the population mean from the raw score or data point in question a test score height age etc then dividing the difference by the population standard deviation.

So if for example you get a z score equal to 2 3 then you can say that it is 2 3 standard deviations below the mean. Values above the mean have positive z scores while values below the mean have negative z scores.

Negative z score chart value is to the left of the mean. Another way to interpret z scores is by creating a standard normal distribution also known as the z score distribution or probability distribution. Positive z score chart value is to the right of the mean.

In figuring out statistics problems make sure you understand how to use the z table to find the probabilities you want. Corresponding values which are less than the mean are marked with a negative score in the z table and respresent the area under the bell curve to the left of z.
