Testable Hypotheses 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 “testable” mean in psychology?

You can measure it to see if it is right or wrong.

What does operationalise mean?

Say exactly how to measure something.

What is an alternative hypothesis (H1)?

A prediction that there is a difference or relationship.

What is a null hypothesis (H0)?

A prediction that there is no difference or relationship.

What is a directional (one-tailed) hypothesis?

It states the expected direction, like more or less.

What is a non-directional (two-tailed) hypothesis?

It says there will be a difference or relationship, but not which way.

When should you use a directional hypothesis?

When previous findings suggest a clear direction.

When should you use a non-directional hypothesis?

When evidence is mixed or unclear.

Why write the null hypothesis as well as H1?

To check if any result is real or due to chance.

How do you make a hypothesis testable?

Use clear, measurable terms and be specific.
