Independent variables are factors or conditions that are manipulated or categorized to determine their effect on dependent variables in an experiment or study. They are essential for establishing cause-and-effect relationships and are crucial in hypothesis testing and experimental design.

Dependent variables are the outcomes or responses that researchers measure in an experiment to assess the effect of independent variables. They provide insight into causal relationships by reflecting changes that occur due to manipulations in the experimental setup.

Factors are numbers or expressions that multiply together to yield a given product, playing a crucial role in various mathematical operations, including simplification, solving equations, and understanding number properties. They are foundational in arithmetic, algebra, and number theory, as they help identify divisibility, prime numbers, and the greatest common divisors.

Hypothesis testing is a statistical method used to make decisions about the properties of a population based on a sample. It involves formulating a null hypothesis and an alternative hypothesis, then using sample data to determine which hypothesis is more likely to be true.

Experimental design is the structured process of planning an experiment to ensure that data collected can be analyzed to yield valid and objective conclusions. It involves careful consideration of variables, controls, and randomization to minimize bias and maximize the reliability of results.
