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.

Enter your answer in the answer box.
[Diagram Explanation]
To the right is a bell curve (normal distribution graph) with a mean (μ) of 100 and a standard deviation (σ) of 15. The graph shows a shaded region to the right of the mean, representing the given probability or area under the curve. This area is labeled 0.6, suggesting that we are looking for the corresponding IQ value where the cumulative area to the right under the curve is 0.6.
