Question

Q6: A researcher summarizes her results of research into the use of a specific type of inhaler for asthma sufferers as follows: 'predictors significantly favored inhaler use (adjusted R2= .38; p = .015). Inhaler A was the strongest predictor of improved breathing ( = .39; p = .001) followed by inhaler B ( = .28; p= .0015)'. What statement could be made about the findings noted in these results?

a. 62% of the variation in results of inhaler use (A or B) is due to other factors.

b. None of the above

c. 72% of the variation in results of inhaler use (A or B) is due to other factors.

d. 38% of the variation in results of inhaler use (A or B) is due to other factors.

Q7: Logistic regression is used when you want to:

a. Predict a dichotomous dependent variable from continuous or dichotomous independent variables

b. Predict a continuous variable from dichotomous or continuous variables.

c. Predict a continuous variable from dichotomous ones

d. Predict any categorical variable from other categorical variables

Explanation / Answer

Q-6

Part-A is correct because adjusted R2=0.38 so 38% explained and remaining 62 % unexplained.

Q-7

Part-A is correct as in logistic regression dependent variable is dichotomous and predictor can be continuous of dichotomous.
