Cards in this deck (18)
- 1PhyscologyStudy of soul and mind
(human behaviour) - 2PseduoscienceAn Imitation of physcology - doesn't follow the scienctific method.
- 3Cause & EffectA simple experiment is one of the most basic methods of determining whether there is a cause-and-effect relationship between two variables.
- 4POPULATIONThe group of people you are studying or researching
EXAMPLE
Primary school students - 5SAMPLEThis is the subgroup of the population that represents the population.
This makes research simpler
EXAMPLE
60 primary students between the age of 8-12 - 6PARTICIPANTA person (or animal) taking part in the stud
- 7SAMPLINGThe method by which participants are selected for the study
- 8RANDOM SAMPLINGEvery person in the population has an equal chance of being selected
E.G HAT DRAW - 9STRATIFIED SAMPLINGThe problem with random is you could miss a particular group
In stratified sampling the population is divided into groups called strata and the sample is then drawn from these groups
e.g stats - 10VAIRABLESA variable is a factor or element that can change in observable and measurable ways. There are three major types of variable that must be considered
- 11INDEPENDENT VARIABLEThe IV is the variable that is of interest to the researcher.
They want to know whether the IV will cause an effect.
EXAMPLE
often a treatment being tested.
Sugar - 12DEPENDENT VARIABLEThe DV is the variable that is being measured
It is a response to the IV.
If the IV is the cause, then the DV is the effect
EXAMPLE
what is the participant’s response to the treatment?
Were the kids more active after the sugar - 13EXTRANEOUS VARIABLEThese are variables that may influence the DV and therefore affect the results.
They are sometimes called a ‘nuisance’ as they really need to be controlled for.
EXAMPLE
the intelligence of participants could affect results.
How active students already are - 14CONTROL GROUPThe group of participants who do not receive the IV
EXAMPLE
they do not receive the treatment being tested.
Measurements taken from the control group are then used as a ‘baseline’ against which those in the experimental group are compared to determine if the treatment had an effect. - 15EXPERIMENTAL GROUPThe group who receive the IV
- 16RESEARCH (EXPERIMENT)An experiment is a study or test used to establish cause and effect,
conducted in an environment under the control of the researchers.
This type of study is often used to determine the effect of a treatment.
Participants are randomly allocated into either a control group or an experimental group. - 17RESEARCH (NATURAL OBSERVATION)Psychologists observe people or animals in their natural habitat without being seen or noticed
ADVANTAGE:
People or animals would then behave as they would normally
DISADVANTAGE:
Little or no control over variables. - 18RESEARCH
