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