Replication of Results Flashcards

1️⃣ Familiarise yourself with the flashcards:

  • Look through all the flashcards to see what's on both sides.
  • Make sure you understand the information on each card. If something's unclear, click the link to the revision notes at the bottom of the page for more details.

2️⃣ Test yourself:

  • Look at the question or prompt on each card and try to remember the answer before flipping it over.
  • Check the answer and make a note of any cards you find challenging and need to go over more.

3️⃣ Consistently Review and Practice:

  • Use spaced repetition: spend more time on the cards you struggle with and go over them more often.
  • Regularly review all the flashcards to help you better understand and retain the information over time.

Note: We may include questions that have multiple correct answers. It's useful to remember specific examples to understand these concepts better.

What does 'replication of results' mean in science?

It means repeating an investigation to see if you get the same results.

Why is replication of results important?

It checks that results are reliable and not just due to chance or a mistake.

Who should carry out replication of a study?

Other, independent scientists should repeat the study using the same method.

How does successful replication affect confidence in results?

If many replications agree, scientists have more confidence the results are correct.

What does it suggest if results cannot be replicated?

It suggests the original results may be wrong, biased, or not clear enough.

How is replication different from taking repeat readings in one experiment?

Repeat readings are done by one group, but replication is the whole study repeated by others.

Why do scientists sometimes replicate results with larger samples?

Larger samples help show if the pattern is real and not due to a few unusual results.

Why might scientists replicate results in different places or conditions?

To see if the same pattern happens in other settings, not just in one lab or area.

How does replication help when a new scientific explanation is suggested?

Replicated results give strong evidence that can support or challenge the new explanation.

Why should methods be described clearly in reports to allow replication?

Clear methods let other scientists copy the study exactly and test the results.
