Determine which of the following options best describes the main purpose for using Figure 2. O Display probabilities of outcomes from a quantitative discrete random variable and decide which outcome is more likely to occur. Display the five number summaries of the data and check whether the data has outliers. O Check whether the data is skewed. O Display the frequency of each category and identify the category with the lowest or highest frequency. Bill Depth (mm) 7.5 8.5 9.0
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.
