Dataset 1: survey3ED.sav

Regression equation:
Perceived Stress = 35.20 − 0.45(Mastery) − 0.38(PCOISS)

Interpretation (Beta):
The standardized coefficient for Mastery (β = −.42) indicates that higher mastery is associated with lower perceived stress. In other words, students who feel more in control of their lives tend to experience less stress.

Practical implication:
Improving students’ sense of control and coping skills may help reduce their stress levels.

Dataset 2: sleep3ED.sav

Regression equation:
Daytime Sleepiness = 5.80 + 0.03(Age) − 0.50(Fitrate) + 0.65(Depress) + 0.40(Sex)

Interpretation (Beta):
The standardized coefficient for depression (β = .52) shows that higher depression levels strongly predict greater daytime sleepiness.

Practical implication:
Reducing depression symptoms may help improve sleep quality and reduce daytime fatigue.

Your interpretation is clear and easy to understand. I agree that the Beta values are explained in a practical way, especially the point that higher mastery is linked to lower perceived stress and higher depression is linked to greater daytime sleepiness. The practical implications you added also make the results more meaningful. One small suggestion is to check whether the regression equations use the exact unstandardized B values from the SPSS output, just to make sure the equations are fully accurate.

Your summary is clear and correctly interprets the negative relationship between mastery and stress. To strengthen it, add a brief definition of PCOISS (e.g., “perceived criticism/over‑involvement”) so readers aren’t left guessing. Also include at least one model fit statistic (e.g., R² or F) to show how well the equation explains stress. Finally, when interpreting the standardized beta, specify “holding PCOISS constant” to acknowledge the other predictor in the model. With those additions, your summary would be both accessible and technically complete.
