A student has a semester GPA of 2.5 based on 15 credit hours. This included an F in a 4 credit hour class. If the student had withdrawn in time, what would be the revised GPA?
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.

Introduction:
Suppose for a particular student, the ith subject had ci credit hours, and the student obtains a grade-point of xi in that subject, in a semester. If the student takes n such classes, then the total number of credit hours is Σ ci, for all i ∈ [1, n] and the grade point average is,
GPA = (Σ xi ci) / (Σ ci).
By convention, a grade F indicates a 0 grade-point.
