Question

unit 1: introduction to biology study guide scientific method: define the following terms: • hypothesis: • independent variable: • dependent variable: • control variable:: • accuracy: • precision: • theory: • law:

Explanation:

To solve this, we define each term related to the scientific method (relevant in Natural Science, specifically Biology here):

Hypothesis:

A testable prediction, often in an "if - then" format, that attempts to explain a phenomenon or answer a scientific question.

Independent Variable:

The variable that is deliberately changed or manipulated by the experimenter in a scientific experiment. It is the factor hypothesized to cause a change in another variable.

Dependent Variable:

The variable that is observed, measured, or expected to change in response to the manipulation of the independent variable. Its value "depends" on the independent variable.

Control Variable:

Variables that are kept constant throughout an experiment. They are not the focus of the study but are controlled to ensure that any changes in the dependent variable are due to the independent variable and not other factors.

Accuracy:

Refers to how close a measured value is to the true or accepted value. It indicates the correctness of a measurement.

Precision:

Refers to how close repeated measurements of the same quantity are to one another. It reflects the consistency of measurements.

Theory:

A well - substantiated explanation of some aspect of the natural world that is based on a large body of confirmed observations, experiments, and reasoning. It is broader in scope than a hypothesis and can be used to make predictions.

Law:

A descriptive statement (often in mathematical form) that reliably predicts events under certain conditions in the natural world. It describes a phenomenon but does not necessarily explain why it occurs (unlike a theory).

If you need more detailed or specific explanations for any of these terms, please let me know!
