Researchers, especially quantitative researchers, study variables and the relationships that exist among them.
⬇️
variable is a construct or a characteristic that can take on different values or scores across people or things.
Examples:
⭕️ Height
⭕️ weight
⭕️ intelligence
⭕️ vocabulary
⭕️ scores
⭕️ gender
💠 Types of Variables
There are several ways to classify variables.
💢 Variables can be categorical, or they can be continuous .
✔️ When researchers classify subjects by sorting them into mutually exclusive groups, the attribute on which they base the classification is called a categorical variable .
Examples:
📍Home language
📍father’s occupation
📍marital status
📍state of birth
✔️ The simplest type of categorical variable has only two mutually exclusive classes and is called a dichotomous variable.
Examples:
📎 pass–fail
📎 citizen–immigrant
📎 in-state or out-of state resident
✔️ When a variable has an infinite number of values within a range, it is a continuous variable.
Examples:
🌀Height
🌀weight
🌀age
🌀achievement test score
💢 Another important classification is whether the variable in a study is the independent variable or a dependent variable.
✔️ The independent variable is the antecedent variable that an investigator manipulates in order to determine its effect on another variable called the dependent variable.
✔️ The dependent variable is the variable we observe and measure.
🔳 Constants
✔️ The opposite of variable is constant ➡️ a constant is a fixed value within a study.
