Consider the following data: 5.3, 5.5, 7.5,7.7,7.7, 7.7,7.7, 7.9, 7.9,7.9,8.1,8.0,8.2,8.4,8.6,8.6,8.8, 8.8, 8.9. The First Quartile value, Q1, of this data set is: The Second Quartile value, Q2, of this data set is: The Third Quartile value, Q3, of this data set is: The Inter Quartile Range, IQR value, of this data set is: The interval for outlier detection using the Quartile infromation for this data set is:
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.
