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.

Given Information :
A small hospital wants to create a more welcoming environment for patients with mental illnesses--starting with employee training. As part of a pre-training assessment, employees complete a 10-point Attitudes Toward Mental Illness scale (higher = more positive attitudes). The pre-training data is provided .
- The frequency of a particular data value is the number of times the data value occurs. The frequency of a data value is often represented by f.
- A frequency table is constructed by arranging collected data values in ascending order of magnitude with their corresponding frequencies.
