Detailed explanation-1: -A variable is anything that can change or be changed. In other words, it is any factor that can be manipulated, controlled for, or measured in an experiment. Experiments contain different types of variables.
Detailed explanation-2: -In research, variables are any characteristics that can take on different values, such as height, age, temperature, or test scores. Researchers often manipulate or measure independent and dependent variables in studies to test cause-and-effect relationships. The independent variable is the cause.
Detailed explanation-3: -The independent variable is the variable that is deliberately changed by the scientist. The dependent variable is the one observed during the experiment.
