Consider the provided five‑number summary: Minimum =4,?1=8, ?=12,?3=15=4, Q1=8 ,M=12, Q3=15 , Maximum =19 . Which set of seven numbers have the same five‑number summary? 4,8,10,12,17,16,20 1,5,12,11,13,15,19 4,8,9,12,14,15,19 4,8,11,13,11,14,19
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.
Consider the provided five‑number summary:
Minimum =4,?1=8, ?=12,?3=15=4, Q1=8 ,M=12, Q3=15 , Maximum =19 .
