We try to determine if we can use educational background, interests, and gender to predict an individual's economic status (poor, average, high), which test should we use?
Select one:
a. Pearson's Correlation
b. Logistic regression
c. ANCOVA
d. Multiple regression
Homework Answers
ANCOVA is used to test the effect of categorical variables on a continuous dependent variable. Hence,
Option C is correct.

7. A study was conducted to investigate the effectiveness of a new drug for treating Stage 4 AIDS patients. A group of AIDS patients was randomly divided into two groups. One group received the new drug; the other group received a placebo. The difference in mean subsequent survival (those with drugs - those without drugs) was found to be 1.04 years and a 95% confidence interval was found to be 1.04 ± 2.37 years. Based upon this information: Select one...

Problem 1 (Logistic Regression and KNN). In this problem, we predict Direction using the data Weekly.csv. a. i. Split the data into one training set and one testing set. The training set contains observations from 1990 to 2008 (Hint: we can use a Boolean vector train=(Year < 2009)). The testing set contains observations in 2009 and 2010 (Hint: since train is a Boolean vector here, should use ! symbol to reverse the elements of a Boolean vector to obtain the...

Future Time Orientation and Condom Use for AIDS
Prevention
Background Notes: Researchers administered questionnaires to
male college students taking an introductory psychology course.
Among other things, they measured future time orientation defined
as planning ahead for future events and willingness to delay
gratification. (Sample item: “I believe that a person’s day should
be planned ahead.”) Based on the scores on the future time
orientation scale, they split the male students into two groups –
one low in future orientation and...
