Expert Solution

1.ANSWER

Discriminant analysis is a technique that is used by the researcher to analyze the research data when the criterion or the dependent variable are categorical and the predictor or the independent variable are interval in nature

The term categorical variable means that the dependent variable is divided into a number of categories. For example, three brands of computers, Computer A, Computer B and Computer C can be the categorical dependent variable.

A categorical variable, also called a nominal variable, is for mutual exclusive, but not ordered, categories.

A interval variable is a measurement where the difference between two values is meaningful. eg:-The difference between a temperature of 100 degrees and 90 degrees is the same difference as between 90 degrees and 80 degrees.

So option C is correct

2.ANSWER

Discriminant Score

when the unstandardised coefficients are multiplied by the values of the variables and the products are summed and added to the constant term.

So option B is correct

Refresher on Variables: Classifying variables as independent or dependent: The independent variable is the one being manipulated or grouped in the study for comparison. A tip to remember this is to think that independent starts with “I” and I, the researcher, manipulate that variable or have control over who is grouped in the study. The way we will be using independent variables in this course is in terms of between group analysis, so our focus will be on groups being...
