Use the positive Z score table below to find values on the right of the mean as can be seen in the graph alongside. Corresponding values which are greater than the mean are marked with a positive score in the z-table and respresent the area under the bell curve to the left of z.
We will use a positive Z-Score table or a negative Z-Score table depending on whether our Z-Score is positive or negative, respectively. Example: Let us learn how to map a Z-Score on a Z-Table using an example.
Z-Scores or Standard Scores. Each number on the horizontal axis of a Standard Normal Distribution curve corresponds to Z-Score also most commonly known as a Standard Score. Z-Score tells us how many standard deviations an observation is from the mean μ.

The Altman Z Score is a formula or a model created by Mr. Edward Altman which assesses a companies’ financial stability and predicts how likely a company is to go bankrupt. It lets us predict the financial distress of a company and how high or low the probability is of the company becoming insolvent in near future of about 2 years.
Z score indicates the position of a raw score from the mean value of the data set in the standard deviation units. The Z score not only gives the measure of the deviation of an element but also indicates the exact position of the raw score with respect to the mean.
We always use pre-made Z Tables but have you ever wondered where the values in a Z Table come from and how a Z Score Table is created from scratch?
Before listing all the various probability distributions in statistics, let us first understand the big broad bifurcations of the types of probability distributions in statistics namely: Discrete Probability Distributions and Continuous Probability Distributions
Determining the critical value of Z from the Z table. The critical value is the point in the normal distribution graph that splits the graph into two regions: the acceptance region and the rejection regions.
In probability and statistics, variance is defined as the expected value of the squared deviation of a random variable from its mean value. It can also be described as the measurement of the spread between each number in a data set. Variance indicates variability.
