Experiments
Definition
Experiments are a type of research method where the researcher manipulates one variable (independent variable) to determine its effect on another variable (dependent variable).
Analogy
Consider experiments as cooking recipes. The ingredients you change (like adding more salt) represent the independent variables while the taste of your dish represents the dependent variable - it changes based on how much salt you add!
