Hypothesis Practice 24/25

Front

What is a hypothesis?

Back

A hypothesis is a testable statement that predicts the relationship between two variables, typically formulated as 'If [independent variable], then [dependent variable], because [reason].'.

Front

What is the independent variable (IV)?

Back

The independent variable is the factor that is changed or manipulated in an experiment to observe its effect on the dependent variable.

Front

What is the dependent variable (DV)?

Back

The dependent variable is the factor that is measured or observed in an experiment, which is affected by changes in the independent variable.

Front

What does the 'because' part of a hypothesis explain?

Back

The 'because' part of a hypothesis provides the reasoning or background research that supports the prediction made in the hypothesis.

Front

Why is it important to have a specific level of the IV in a hypothesis?

Back

Having a specific level of the IV allows for clear and measurable outcomes, making it easier to analyze the results of the experiment.

Front

What is the purpose of background research in forming a hypothesis?

Back

Background research helps inform the hypothesis by providing context, previous findings, and understanding of the topic being studied.

Front

What is the role of in-text citations in scientific writing?

Back

In-text citations give credit to the original sources of information used in the writing and must correspond with full citations at the end of the work.

Front

What is a controlled experiment?

Back

A controlled experiment is one in which all variables are kept constant except for the independent variable, allowing for a clear cause-and-effect relationship to be established.

Front

What is the significance of testing a hypothesis?

Back

Testing a hypothesis is crucial for validating or refuting the prediction, contributing to scientific knowledge and understanding.

Front

What is an example of a hypothesis?

Back

If plants are placed in bright light, then they will grow the most green leaves because leaves need sunlight to produce glucose.
