Question 125092: 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
98,85,30,66,99,95,57,62,99,100
Group B Scores
64,81,62,88,82,79,90,81,85,79
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?

You can put this solution on YOUR website! 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
98,85,30,66,99,95,57,62,99,100
mean = 71.9
standard deviation = 24.122
Max = 100-------------------------
Group B Scores
64,81,62,88,82,79,90,81,85,79
mean = 71.9
Standard deviation = 9.243
Max = 81
You must decide which group to choose.
Choose Group B
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.
The two groups have the same mean but Group B has less variability
about that mean as shown by a smaller standard deviation and smaller
max score.

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?
I'll leave this to you.
