Flashcard on Scientific Concepts

Front

What does it mean if an experiment is reliable?

Back

It means that the experiment yields the same results every time it is performed.

Front

Define validity in the context of an experiment.

Back

Validity refers to whether the experiment measures what it is intended to measure.

Front

What is a hypothesis?

Back

A hypothesis is a testable prediction about the outcome of an experiment.

Front

What does accuracy mean in scientific experiments?

Back

Accuracy means that the results are close to the true value.

Front

What can be said about measurements that are both accurate and precise?

Back

They are close to the true value and consistent with each other.

Front

What is precision in scientific measurements?

Back

Precision refers to the consistency of repeated measurements.

Front

How can you determine if an experiment is valid?

Back

An experiment is valid if it accurately measures what it is supposed to measure.

Front

What is the difference between accuracy and precision?

Back

Accuracy is about how close a measurement is to the true value, while precision is about how consistent the measurements are.

Front

What is the role of a control group in an experiment?

Back

A control group serves as a baseline to compare the effects of the experimental treatment.

Front

What is the scientific method?

Back

The scientific method is a systematic process for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge.
