Research Methods: IV DV AIM Flashcards

1
Q

What is an Independent variable?

A

The variable that changes OR is manipulated by the researcher to see if it has an effect on the DV.

Q

When identifying the IV in an experiment what must you look for?

A

Look for the different conditions - the factor that is changing will be the IV.

Q

Define operationalisation?

A

Operationalisation means to be specific and clear when defining the independent and dependent variable in an experiment, to make it easier to measure.

Q

Why is operationalising important?

A

If variables are vague (not operationalised) then it would not be possible to repeat the research to check for consistent results.

Q

How does operationalisation impact reliability?

A

Operationalisation increases reliability as if variables are operationalised the other researchers can repeat the research in the same way to check for consistent results.

Q

Practice: Operationalised ‘memory.’

Top tip: You need to provide the scale or measurement where possible.

A

e.g. number of words correctly recalled out of 30

Q

What is the difference between an aim and a hypothesis?

A

This is a general statement of what the researcher intends to investigate
whilst
a hypothesis is a specific testable statement in which the researcher predicts what will happen between the variables.

Q

An experiment was conducted under the following conditions:

Condition 1: 20 people learned and recalled Word list A in the same location.
Condition 2: The same 20 people learned Word list B in one location and recalled Word list B in a different location.

Identify the operationalised dependent variable in this study.

A

Number/amount of words recalled correctly (from word lists or word list A and word list B).
