Section 8.14 Example APA-style Write-up
The following example demonstrates one acceptable way to report the results of a simple linear regression in APA style.
Simple Linear Regression
A simple linear regression was conducted to examine whether pizza price predicted weekly pizza sales volume. The overall regression model was statistically significant, \(F(1, 148) = 116.60, p < .001\text{,}\) and explained approximately 43% of the variance in pizza sales volume (\(R^2 = .43\)).
Pizza price was a significant negative predictor of sales volume, \(b = -111,669\text{,}\) \(SE = 10,347\text{,}\) \(t = -10.80\text{,}\) \(p < .001\text{,}\) indicating that higher pizza prices were associated with lower weekly sales volume. Specifically, for each one-unit increase in pizza price, weekly pizza sales decreased by approximately 111,669 units.
