Detailed explanation-1: -The difference in a variable measured over observations (time, customers, items, etc.) is known as the variance.
Detailed explanation-2: -A variable contains all values that measure the same underlying attribute (like height, temperature, duration) across units. An observation contains all values measured on the same unit (like a person, or a day, or a city) across attributes.
Detailed explanation-3: -The variable which is measured in an experiment is the dependent variable. An experiment is a scientific procedure in which scientists measure the effect of a single independent variable on the quantity of a dependent variable. All other factors are kept as constant as possible during experiments.
Detailed explanation-4: -You can see that one way to look at variables is to divide them into four different categories ( nominal, ordinal, interval and ratio).
Detailed explanation-5: -An experimental inquiry typically has three main types of variables: an independent variable, a dependent variable and controlled variables.
