Detailed explanation-1: -Interval variables are variables for which their central characteristic is that they can be measured along a continuum and they have a numerical value (for example, temperature measured in degrees Celsius or Fahrenheit).

Detailed explanation-2: -Continuous variables are measured along a continuum, such that they can be measured at any point beyond the decimal point. Continuous variables can be measured in whole or fractional units. Discrete variables are measured in categories or whole units and are not measured along a continuum.

Detailed explanation-3: -Numeric variables A numeric variable (also called quantitative variable) is a quantifiable characteristic whose values are numbers (except numbers which are codes standing up for categories). Numeric variables may be either continuous or discrete.

Detailed explanation-4: -A continuous variable is considered interval if it can be measured along a continuum that has fixed values between two points, but does not have a meaningful zero-point (e.g., temperature measured in Fahrenheit or Celsius). The level of measurement of your variables influences what analyses you can conduct.

Detailed explanation-5: -An interval scale is one where there is order and the difference between two values is meaningful. Examples of interval variables include: temperature (Farenheit), temperature (Celcius), pH, SAT score (200-800), credit score (300-850).
