The numbers of regular season wins for 5 football teams in a given season are given below. Determine the range, mean, POPULATION variance, and POPULATION standard deviation of the population data set. Do not upload to excel since there are only FIVE values and it may not load correctly. You must upload your work for this question to BLACKBOARD. 15,14,10,9,2 O The range is (Simplify your answer.) The population mean is. (Simplify your answer. Round to the nearest tenth as needed.) The population variance is. (Simplify your answer. Round to the nearest tenth as needed.) The population standard deviation is. (Simplify your answer. Round to the nearest tenth as needed.)
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.
