TABLE 14-18 A Logistic Regression Model Was Estimated in Order to Predict

question 30

Short Answer

TABLE 14-18
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).
The Minitab output is given below:
-Referring to Table 14-18, what is the p-value of the test statistic when testing whether SAT makes a significant contribution to the model in the presence of the other independent variables?

Definitions:

Hypothetical Variable

A variable that is not directly observable, proposed to explain relationships and effects in scientific models.

Dependent Variable

In research, the variable that is being measured or tested to see how it is affected by changes in another variable (the independent variable).

Independent Variable

The variable in an experimental study that is manipulated by the researcher to investigate its effect on the dependent variable.

Control Variable

A variable that is kept constant during a scientific experiment to ensure that the effect of the independent variable on the dependent variable is observed without interference.
