GCSE Psychology Research Methods -Experiments Video 2

What are the three types of experiments covered at the GCSE level?

• Quantitative, Qualitative, and Mixed-method experiments

• Descriptive, Correlational, and Causal experiments

• Controlled, Uncontrolled, and Semi-controlled experiments

• Lab, Field, and Natural experiments

What is a characteristic feature of lab experiments?

• They are conducted in a highly controlled environment

• They have a high degree of external validity

• They take place in a natural setting

• They involve observing behaviors without intervention

What is a strength of field experiments?

• They are more applicable to real life

• They are cheaper to conduct than natural experiments

• They are easier to control than lab experiments

• They have no demand characteristics

Why are natural experiments hard to replicate?

• Because they do not involve any manipulation of variables

• Because they require a large number of participants

• Because the same conditions in an uncontrolled environment are rare

• Because they are conducted in a controlled lab setting

What does experimental design refer to?

• The technique for ensuring experiments are ethical

• The process of selecting the research topic

• The method used to analyze data

• The way participants are ordered in a study

What is a way to counteract order effects in repeated measures design?

• Conducting the experiment in a natural setting

• Switching to an independent groups design

• Increasing the number of participants

• Counterbalancing the order of conditions

What is a disadvantage of independent groups design?

• It completely avoids order effects

• It can get expensive due to needing more participants

• It is less time-consuming than matched pairs

• It eliminates participant variables

What is matched pairs design aimed at reducing?

• The cost of the experiment

• The need for a large sample size

• The complexity of data analysis

• Participant variables and order effects

In the context of lab experiments, what does controlling the independent variable help to measure?

• The cost-effectiveness of the research

• The external validity of the experiment

• Its effect on the dependent variable

• The number of participants required

Why are tasks in lab experiments often considered artificial?

• Because they are conducted outside of a controlled environment

• Because they are harder to apply to real-world situations

• Because they involve high levels of participant interaction

• Because they replicate real-world situations exactly
