Answer the 11 questions. Please note a couple you need to complete the blank in the table.
4. Partial gamma
Consider the following bivariate table showing the relationship between the amount of missed work days (frequency of absence: low or high) and the amount of monthly sales (classified as either low or high, based on company-wide averages) among sales personnel at a car dealership:
Frequency of Absence (X) | |||
---|---|---|---|
Monthly Sales (Y) | Low | High | Totals |
Low | 45 | 30 | 75 |
High | 44 | 103 | 147 |
Totals | 89 | 133 | 222 |
Gamma = +0.5567 |
1. The data in the table suggest that there is ___________ association between the amount of missed work days and the amount of monthly sales.
The partial tables showing the bivariate relationship between the amount of missed work days and the amount of monthly sales after controlling for level of education follow. Compute and select the correct value for gamma from the dropdown menu for each of these partial tables.
A. High School
2. Answer the blank
Frequency of Absence (X) | |||
---|---|---|---|
Monthly Sales (Y) | Low | High | Totals |
Low | 25 | 9 | 34 |
High | 28 | 31 | 59 |
Totals | 53 | 40 | 93 |
Gamma = _______ |
B. College
3. Answer the blank
Frequency of Absence (X) | |||
---|---|---|---|
Monthly Sales (Y) | Low | High | Totals |
Low | 20 | 21 | 41 |
High | 16 | 72 | 88 |
Totals | 36 | 93 | 129 |
Gamma = _________ |
4. Compared with the bivariate table, the partial tables show ____________ relationship between X and Y. This is evidence of __________ relationship between the variables and implies that you should _________ the variable Z (level of education) in further analysis.
5. Since you found ____________ relationship between X and Y, you can proceed to calculate the partial gamma GpGp. Follow and complete the steps that follow to calculate GpGp:
6. Step 1: Add up the values for Ns from all partial tables. Ns =____________
7. Step 2: Add up the values for Nd from all partial tables. Nd= ___________.
8. Step 3: Subtract Ns from Ns. NsNd= __________.
9. Step 4: Add Nd to Ns. Ns+Nd = ______________.
10. Step 5: Divide the quantity you found in Step 3 by the quantity you found in Step 4 to find Gp. Gp = ___________.
11. The value of the partial gamma is ___________ the value of the bivariate gamma G=0.5567. This ___________ the conclusion you drew from the partial tables about the relationship between the amount of missed work days and the amount of monthly sales.
