Testable Question
Testable Question
A testable question is one that can be answered through experimentation or observation. It is phrased in a way that allows for a clear and measurable outcome.
Hypothesis
Hypothesis
A hypothesis is a proposed explanation for an observation or phenomenon. It is a testable statement that suggests a possible relationship between variables.
Independent Variable
Independent Variable
The independent variable is the factor that is changed or manipulated in an experiment. Its effect on the dependent variable is being investigated.
