Suppose you and two friends decide to cheat on a quiz in your statistics class. There are 3 types of questions on the quiz and only 8 problems on the quiz. The question bank being used contains 5 problems of Type (I), 4 problems of Type (II), and 6 problems of Type (III). There will be 3 questions of Type (I), 1 question of Type (II), and 4 questions of Type (III) on your quiz. What is the probability that 2 people in your group have the exact same questions?
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.
