Be a Simpson Can you design a Simpson’s paradox? Twocompanies are vying for a city’s “Best Local Employer”award, to be given to the company most committed tohiring local residents. Although both employers hired300 new people in the past year, Company A brags that itdeserves the award because 70% of its new jobs went tolocal residents, compared to only 60% for Company B.Company B concedes that those percentages are correct, but points out that most of its new jobs were full-time,while most of Company A’s were part-time. Not only that,says Company B, but a higher percentage of its full-timejobs went to local residents than did Company A’s, andthe same was true for part-time jobs. Thus, Company Bargues, it’s a better local employer than Company A.Show how it’s possible for Company B to fill a higherpercentage of both full-time and part-time jobs with local residents, even though Company A hired more local resi-dents overall.
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.
