A researcher summarizes her results of research into the use of a specific type of inhaler for asthma sufferers as follows: 'predictors significantly favoured inhaler use (adjusted R²= .38; p = .015). Inhaler A was the strongest predictor of improved breathing (β = .39; p = .001) followed by inhaler B (β = .28; p = .0015)'. Which of the following would be the best interpretation of the variables in relation to these results? A) 39% of the variation in inhalers B) 28% of the variation in inhalers C) 38% of the variation in inhalers D) None of the above

The adjusted R² value of .38 indicates that 38% of the variation in inhaler use can be explained by the predictors. Additionally, the β values provide information about the strength and direction of the relationship between each predictor and improved breathing, but they do not indicate the percentage of variation accounted for.
