TABLE 17-11 A Logistic Regression Model Was Estimated in Order to Predict

question 171

Multiple Choice

TABLE 17-11
A logistic regression model was estimated in order to predict the probability that a randomly chosen university or college would be a private university using information on mean total Scholastic Aptitude Test score (SAT) at the university or college,the room and board expense measured in thousands of dollars (Room/Brd) ,and whether the TOEFL criterion is at least 550 (Toefl550 = 1 if yes,0 otherwise.) The dependent variable,Y,is school type (Type = 1 if private and 0 otherwise) .
-Referring to Table 17-11,which of the following is the correct interpretation for the SAT slope coefficient?

• A)Holding constant the effect of the other variables,the estimated mean value of school type increases by 0.015 for each increase of one point in average SAT score.
• B)Holding constant the effect of the other variables,the estimated school type increases by 0.015 for each increase of one point in average SAT score.
• C)Holding constant the effect of the other variables,the estimated probability of the school being a private school increases by 0.015 for each increase of one point in mean SAT score.
• D)Holding constant the effect of the other variables,the estimated natural logarithm of the odds ratio of the school being a private school increases by 0.015 for each increase of one point in mean SAT score.

Definitions:

Behavioral Contrast

A phenomenon in which the response rate to one stimulus changes as a result of a change in the reinforcement offered for another stimulus.

Second-order Conditioning

A form of learning where a stimulus that was previously neutral is associated with a conditioned stimulus to elicit the same conditioned response, without the original unconditioned stimulus.

Habituation

A procedure in which a life form diminishes or halts its response to a recurring stimulus as time goes by.

Sensitization

The process where repeated administration of a stimulus results in the progressive amplification of a response.
