Question

2. A psychologist was interested in whether the amount of news people watch (minutes per day) predicts how depressed they are (from 0 = not depressed to 7 = very depressed). What does the standardized beta tell us in the output?

coefficients

unstandardized coefficient standardized coefficient 95% confidence intervalfor B collinearity statistics

model 1 B standard error beta t sig. lower bound upper bound tolerance vif

a. dependent variables

a. As news exposure decreases by 0.224 standard deviations, depression increases by 1 standard deviation.

b. As news exposure increases by 1 minute, depression decreases by 0.224 units.

c. As news exposure decreases by 0.224 minutes, depression increases by 1 unit.

d. As news exposure increases by 1 standard deviation, depression decreases by 0.224 of a standard deviation.

Explanation / Answer

Standardized coefficients refer to how many standard deviations a dependent variable will change, per standard deviation increase in the predictor variable.

Here

predictor variable = new exposure

dependent variable = depression

ans) d. As news exposure increases by 1 standard deviation, depression decreases by 0.224 of a standard deviation.
