Your class grade is based on one midterm exam that counts as 25% of your final grade, one final paper that counts as 40% of your final grade, weekly quizzes that counts as 15% of your final grade, and homework assignments that counts as 20% of your final grade. Your midterm exam score is 93, your final paper score is 88, your overall weekly quiz score is 75, and your overall homework assignment score is 90. What is your overall final score for the class?
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.
