The variation of Y around its mean can be decomposed into which two parts?
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.
The variation of Y around its
Note:
Hey there! Thank you for the question. As it is not mentioned whether Y is the response variable in a regression model, or the observations in an ANOVA model, we have explained it to you with the concept of regression. Even if it is the concept of ANOVA that you require, the calculations would not change, but the terminology would differ. If you need further help, please re-post the question and mention the context in which you require this to be answered.
