Things that might affect the outcome of the experiment that you do not control
The thing you change
The process of devising a way of measuring a variable
ETHICS: Doesn't
How much findings can be generalised
Where every member of the target population has an equal chance of selection
Disadvantage of Natural Experiment
The researcher joins in the group they are studying
An in-depth study on a specific group of people (or just the one).
Good thing about Random Sampling
Part of qualitative analysis; the researcher identifies a theme and counts how many times it occurs. Basically converts qualitative data to quantitative data
The IV is manipulated but extraneous variables are not.
A study has this validity if the outcome is the result of the variables manipulated in the study
Measures how widely spread the values in a data set are around the mean
Disadvantage of questionnaires; you write an untrue answer because you don't want to seem bad
Bonus question! Qualitatively, how many neutrons in the brain?
ETHICS: Peasants
Validity a study has if the results of future studies agree with it
Disadvantage of Lab Experiment
How much findings can be generalised to other settings.
Type of data you get from interviews and case studies; give more information
Validity a study has if its results agree with results of previous studies
Advantage of Field Experiment
A general statement about the purpose of the investigation
Participants are randomly allocated to a condition
Advantage of Lab Experiment
Advantage of Natural Experiment
The participants are aware they are being observed. Think Years 7-9 Games showers
ETHICS: Cameron
Type of data you get from surveys; very to throw on a graph
Where the researcher samples anyone they can, ie. questionnaires down the high street
Where the researcher puts an ad out, and people come forward for the study
A measure of central tendancy
The group of participants who do not receive the experimental treatment
ETHICS: Working
Bad Thing about Volunteer Sampling
Example: 'A dog's coat colour influences its obedience'
What the participant may show if they work out the hypothesis of the study
The IV is directly manipulated, all extraneous variables are controlled.
How much findings can be generalised to other people
Disadvantage of Field Experiment
The participants are not aware they are being watched. Stalkers :)
The procedure where only the participants do not know the hypothesis or condition of the study
The same participants are used in both conditions
Disadvantage of correlation
Participants are 'matched up' and do separate conditions
The procedure where both the participants and the research assistant do not know the hypothesis or the conditions of the study.
Asking people for information using written methods, ie. questionnaires
Part of qualitative analysis; only presents the data in verbal form.
Validity a study has if it looks like it makes sense
Example: 'What do you think of this quiz?'
The researcher decides exactly what behaviours they will observe
Evolves from Bellsprout
Example: 'Do you think this quiz is good?'
The thing affected by what you change
ETHICS: Destroy
When the researcher unintentionally affects the results
Example: 'If a dog has a lighter coat, it will be more obedient'
Bad thing about Opportunity Sampling
Any hypothesis that is not the null hypothesis
The IV is not manipulated. No random allocation to conditions.
A test study
The researcher notes down all behaviours in the study and reviews them later on.
Example: 'A dog's coat colour does not influence its obedience'
A precise, testable statement about the expected outcome of the investigation
The researcher makes observations from outside the group being studied
Asking people for information using verbal methods
The simplest measure of dispersion
Advantage of correlation
