What is research/experimental hypothesis?
100
These are the three main parts to a study
What are 'aim, method, findings'
100
Before beginning an experiment, researchers must obtain this from the participants.
What is 'informed consent'?
200
A type of sampling where everyone in the target population has an equal shot of being chosen for the sample.
What is 'random sampling'?
200
This is the variable that the researcher manipulates.
What is 'independent variable'?

These are the two conditions in an experiment.
What is 'control and experimental conditions'
200
This term refers to when a study measures what it is intended to measure.
What is 'validity'?
200
All participants have the right to this, meaning they can leave the experiment if they wish.
What is 'withdrawal'?
300
Sampling method where participants volunteer.
What is 'self-selected sampling'?
300
This type of hypothesis says that the IV will have no affect on the DV.
What is 'null hypothesis'?
300
Define a) repeated measures design and b) independent groups design
What is a) The same participant is tested in both the control condition and the experimental condition. In other words, the same participant is tested twice. b) A comparison is made between two unrelated groups of participants. One group receives the experimental treatment and one group doesn’t.
300
This term refers to when a study reflects what happens in real life.
What is 'ecological validity'?

A problem with experiments is that if they are highly controlled and the environment is artificial, the study may have________

Low ecological validity

500

When an experiment was conducted using appropriate controls so that it supports the conclusion that the independent variable caused observed differences in the dependent variable.

Internal Validity

In research the aim is to be able to take our findings and generalize them to the larger population. Which is known as this.
What is 'generalizability'?
