    Please provide input and answers to the questions below.

    You have administered a standardized test of manual dexterity to two groups of 10 semi skilled workers. One of these two groups of workers will be employed by you to work in a warehouse with many fragile items. The higher the manual dexterity of a worker the less likelihood that worker will break significant inventory. Because of a unique contract you must hire all 10 employees from one of the two groups and none of the employees from the other.

    Group A Scores 77 87 80 91 77 84 90 60 79 66

    Group B Scores 100 99 62 57 95 96 69 32 83 98

    You must decide which group to choose. Consider at least two measures of central tendency and at least one measure of dispersion for each group and use those to make your choice. Be sure to justify your choice with at least one page of discussion and analysis. Can you base a decision on the information provided and the measures that you calculated only?

    Solution Summary

    This solution shows step-by-step calculations in an Excel file to compare the choices of two groups using measures of central tendency and dispersion. An analysis is done based on the mean, median, range and standard deviation of the two groups.
