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.
Box and whisker plot:
A type of graph used to display patterns of quantitative data is called a box plot. Sometimes it is also called box and whisker plot. A box plot splits the data into quartiles. The body of the box plot consists of a box, which goes from the first quartile (Q1) to the third quartile (Q3). The vertical line in the box plot is drawn at Q2, the median of the data set.
In order to understand central tendency and variability, the box plot can interpret in the form of five number summary.
