a. Dependent Variable: weight in kgs

Interpret the beta and significance value for stressful work in the multivariate model.

Interpret the 95% confidence limits for this beta value.

What are your conclusions from the results of this multivariate regression in the light of the simple regression carried out for work stress and weight?

Explanation / Answer

For every 1-unit increase in value for stressful work increases weight by 0.725 kg.

We are 95% confident that for every 1-unit increase in value for stressful work, on average, weight increases by between -.134 and 1.584 kg.

Since p-value for stressful work is greater than 0.05, this suggests that stressful work is not a significant predictor of weight.
