RESEARCH METHODOLOGY

Detailed explanation-1: -Dichotomous variables are categorical variables with two levels. These could include yes/no, high/low, or male/female. To remember this, think di = two. Ordinal variables have two are more categories that can be ordered or ranked.

Detailed explanation-2: -a variable that can have only one of two values (typically, 0 or 1) to designate membership in one of two possible categories, such as female versus male or Republican versus Democrat. Also called binary variable.

Detailed explanation-3: -A nominal variable with two mutually exclusive categories is sometimes called a dichotomous variable. An ordinal-scale variable has values that can be ranked but are not necessarily evenly spaced, such as stage of cancer (see Table 2.3).

Detailed explanation-4: -The dependent variable (DV) is what you want to use the model to explain or predict. The values of this variable depend on other variables. It is the outcome that you’re studying. It’s also known as the response variable, outcome variable, and left-hand variable.
