Instructions: Use the following data set to find the sample statistics for the following data set. (Round answers to the nearest hundredth, if necessary). {32, 33, 21, 51, 44, 25, 35, 82, 55, 47, 52, 38, 39, 43, 48, 51, 53, 37, 40, 1: 1. Five number summary: 15, 33.5, 41.5, 51, 82 (List the numbers in ascending order, separated with a comma and a space. Example: 1, 2, 3, 4, 5.) 2. IQR = 17.5 3. Outliers for this data set would be less than 7.25 x or more than 77.25
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.
