“The Impact of Lifestyle Factors on Sleep Duration” by Jamal C

About the Author

My identify is Jamal Castor, this venture was accomplished as a part of my STA 4164 class. It focuses on making use of regression modeling to research actual world relationships between life-style components and sleep period.

Abstract, Summary, or Creative Statement

This venture examines the impression of life-style components on sleep period utilizing a a number of linear regression mannequin. The dataset was sourced from Kaggle and contains 374 people and varied predictors comparable to stress degree, bodily exercise, coronary heart fee, and age. Exploratory information evaluation revealed a powerful unfavourable relationship between stress and sleep period, whereas bodily exercise confirmed a weaker optimistic relationship.

A regression mannequin was used to check these relationships. The outcomes point out that stress degree is essentially the most important predictor of sleep period, with increased stress linked to decreased sleep. Physical exercise additionally confirmed a statistically important optimistic impact, though a lot smaller. Heart fee and age weren’t discovered to be important predictors.

Model diagnostics, together with residual plots and Q-Q plots, counsel that the assumptions of the regression mannequin are fairly happy. One factor I realized from this venture is the significance of stress administration in bettering sleep outcomes. One limitation of the examine is that the dataset is synthetically generated, that means actual world information would enhance accuracy.
