At the time of the pandemic, as now, almost all universities and schools meet online learning. As a result, sometimes a lot of students who have difficulty in dealing with this teaching and learning process. In the period 2020 Odd predictions student test scores one of the universities in Jakarta is considered normal distribution with an average of 65 and a standard deviation is 13. If the prediction is only 32.5% of students who will graduate to the course Statistics, then a. What is the lowest grade of the student? b. Analysis of your answer based on the answers you get!
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.
