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. #research @Eltprogram @Elt_program
