1. Run a simple regression calculation in EXCEL using BENEFITS as the independent variable and INTRINSIC job satisfaction as the dependent variable using all 29 data points from the AIU dataset.

1.a. Give the graph of the trendline below:

(To do the correlation and regression, the steps in EXCEL are as indicated on page 547, under “Correlation and Regression”.

In order to graph a scatter plot and then insert a trendline in it, you can do the following:

1. Follow the steps on page 92 of the text to get the scatter plot.

2. Once you have the scatter plot, to include the trendline (which is also the regression line). right click directly on one of the dots on the scatter plot. Then select Add Trendline from the shortcut menu that appears)

1.b. Provide the summary results of the regression copied and pasted below from your Excel output, as shown in the text. Do not submit Excel files.

1.c. State regression results below in mathematical form (i.e. in the form y=mx+b), and explain slope and y-intercept and their signs, and explain their meanings:

The regression equation is y = -0.2335x + 6.6398

The slope m = -0.2335, this gives the rate at which intrinsic job satisfaction decreases per unit increase in the benefits.

The y-intercept c = 6.6398; this is the value of intrinsic job satisfaction with no benefits.

1.d. What is the R-squared value and its significance?

The R-squared value is 0.0258. This value lies in the range from 0 to 1 for any regression analysis. The values close to 1 means very good fit of the data and values close to 0 means poor fit of data.

Small value of R-squared in this analysis means that the regression equation will give erroneous results.

The regression equation is y = -0.1459x + 5.9581

The slope m = -0.1459, this gives the rate at which intrinsic job satisfaction decreases per unit increase in the benefits.

The y-intercept c = 5.9581; this is the value of intrinsic job satisfaction with no benefits.

2.d. What is the R-squared value and its significance?

The R-squared value is 0.0053. This value lies in the range from 0 to 1 for any regression analysis. The values close to 1 means very good fit of the data and values close to 0 means poor fit of data.

Small value of R-squared in this analysis means that the regression equation will give erroneous results.

The regression equation is y = -0.3303x + 6.135

The slope m = -0.3303, this gives the rate at which intrinsic job satisfaction decreases per unit increase in the benefits.

The y-intercept c = 6.135; this is the value of intrinsic job satisfaction with no benefits.

3.d. What is the R-squared value and its significance?

The R-squared value is 0.0403. This value lies in the range from 0 to 1 for any regression analysis. The values close to 1 means very good fit of the data and values close to 0 means poor fit of data.

Small value of R-squared in this analysis means that the regression equation will give erroneous results.

4. a. Comment specifically on the similarities and differences in the output results.

The results are similar in the sense that all the three parameters i.e. Intrinsic, Extrinsic and Overall job satisfaction show decreasing trend with increasing benefits. This is evident from the negative value of the slope of the regression line.

4.b. Show formula used to calculate the correlation coefficient.

Correlation coefficient was calculated using the following formula:

Correlation coefficient

4.c. Identify which regression produced the strongest correlation coefficient.

The regression between overall job satisfaction and benefits produced the strongest correlation coefficient.

4.d. Explain why it has the strongest correlation.

This has the strongest correlation because the value of R-squared is the largest for this regression.
