The average weight of an elephant is 6.42 tons with a standard deviation of 1.07 tons. Use the Empirical Rule to answer the following questions. 1) What weight is the mean? ______ 2) What weight is 1 standard deviation above the mean? _____ 3) What weight is 2 standard deviations above the mean? ______ 4) What weight is 3 standard deviations above the mean? _____
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.
