Bivariate, Multiple, and Logistic Regression...

An example of a write up for a regression in an article might read as follows: The regression model identified a significant positive relationship between the dependent variable weight and height (slope=0.25; 95% CI, 0.19-0.31; y=12.6+0.25x; t (451)=8.3, p<.001; r²=0.67).

a. Is the slope of this regression a direct or inverse relationship?

b. Based on this slope what happens to weight as height increases?

Solution

a. Is the slope of this regression a direct or inverse relationship?

Assume that the significant level a=0.05

Since the p-value is less than 0.05, we reject the null hypothesis which is the the slope of this regression is not significant.

Since the value of the slope is positive, we can conclude that the slope of this regression is a direct relationship

b. Based on this slope what happens to weight as height increases?

As height increases, the weight increases.
