The LA county board of education regularly collects data on student SAT scores and classifies these as satisfactory or unsatisfactory. Along with this data, the county collects such information as family income level, number of siblings in the household, number of parents in the household, age, and sex of the student. If an administrator is interested in calculating the probability of a certain student receiving a satisfactory SAT score based on the variables mentioned above, what kind of analysis should they use to accomplish this?

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.
