Regarding the question about whether a hypothesis is a clear and precise definition of a variable:

- The statement "A hypothesis is a clear and precise definition of a variable" is False.

Here's why:
1. Definition of a Hypothesis: A hypothesis is an educated guess or a proposed explanation made on the basis of limited evidence as a starting point for further investigation or experimentation.
2. Nature of a Hypothesis: A hypothesis is more of a proposed explanation or prediction that can be tested through research or experimentation. It is not just a definition of a variable.
3. Variables in Hypotheses: Hypotheses often involve variables, which are factors or characteristics that can vary or change. However, a hypothesis goes beyond just defining a variable; it aims to establish a relationship or make a prediction about how variables are related.
4. Example: For instance, a hypothesis could be "increasing the amount of sunlight will lead to higher plant growth." In this hypothesis, sunlight is a variable, but the hypothesis itself is not just defining the variable; it is proposing a cause-and-effect relationship between sunlight and plant growth.

Therefore, a hypothesis is not simply a clear and precise definition of a variable; it is a statement that suggests a relationship between variables and serves as a starting point for scientific investigation.
