Would the data sets that follow possess relative frequency distributions that are symmetric, skewed to the right, or skewed to the left? a. The salaries of all persons employed by a large company Choose the correct answer below. A. The data set is symmetric because the mean value would be nearly the same as the median value. The measurements would be centered around a single value. B. The data set is skewed left because the mean value would be less than the median value. There would be a few, but small, measurements that would pull the mean away from the median toward the left. C. The data set is skewed right because the mean value would be more than the median value. There would be a few, but large, measurements that would pull the mean away from the median toward the right.

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.
