Question 311195: 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 Group B Scores
99 78
100 86
60 79
59 92
95 75
97 86
67 90
34 59
81 79
96 64
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?
Answer by Fombitz(32388)   (Show Source):
You can put this solution on YOUR website! Group A: Mean=78.8, St.Dev.=21.5
Group B: Mean=78.8, St.Dev.=10.1
The groups have the same mean, with Group A having more variability. CHoose Group B to lower the risk of breakage. They are more likely to have less overall breakage than Group A.
