aims,hypothesis,iv,dv Flashcards
what is the first step researchers must decide on when designing a study
the aim and hypothesis
What are aims
An aim is a general statement of what the researcher intends to investigate – the purpose of the study.
Typically
begins with “To investigate…”
Give an example of an aim
To investigate whether TV/noise impacts the quality of homework produced by students
what is a hypothesis
This is a statement about what you believe to be true/what you expect to find
WHAT THE STUDY IS DESIGNED TO TEST
what does a hypothesis do
It is a clear, precise, testable statement which
states the relationship between the variables to be investigated.
what makes a hypothesis/criteria for writing one
- IV and DV is operationalised
- relationship between IV and DV is clearly stated
comparison is made
Types of hypothesis
directional (kind of diff )
non -directional ( states diff but doesn’t specify direction )
null (assumption that there is no diff )
When each type of hypothesis is used
Directional - when the past research suggests finding go in a particular way
Non - directional = when the past research is unequivocal
Null = used to falsify research
what is DV
what you measure - how are you going to measure the impact of IV
what is IV
Independent variables are variables that researchers change/manipulate
levels of IV
different conditions in a experiment
example of IV
complete a hw task in front of tv vs at a desk with no distractions
What is operationalisation
Operationalisation is making a variable objective and clearly measurable
What does operationalising IV and DV allow
Making sure you varibakes are in a form that can be easily tested/ measured this makes research replicable and repeatable
Example of operationalisation
IV
- complete a 16 mark essay on explanations for conformity while watching Frozen
- complete a 16 mark essay on explanations for conformity at a desk with no distractions
DV
- score recieved for HW
