The mumbers of points scored by player A in the fint 12 games of the 2019-2020 NBA reglar season are listed 29 15 14 22 22 8 19 6 28 18 19 34 a) Find the mean, median and mode of the data set. Which best represents the center of the data? b) Find the mnge, variance, and standard deviation of the sample data set e) Find the coefficient of variation of the data set. 4) Display the data in a stem-and-leaf plot. Use one line per stem. e) Find the zscore for every value in the sample. 9 List this collection of z-scores to create a new sample. Calculate the pew sanple mean Did you get the value you expect? 2) What do you expect the nrw sample standard deviation to be Deot caleulate it
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.
