Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.

In statistics, three measures of central tendency are widely used. These three measures are also called the measures of location. These are the following:
Median
Mode
Mean
These could be defined as follows:
Mean is generally represented as the total sum of all observations divided by the number of observations. It gives an average value for the whole data set. It is the most commonly used measure of central tendency. It includes each and every observation. This makes the mean value sensitive to outliers as it is affected by them.
