Scientific processes Flashcards
(43 cards)
what are aims
the objective or purpose of the experiment
what is bias
an inclination to a certain position or thought
what are behavioural categories
an observational technique wherein participants possible behaviours are separated into more specific components. this allows for operationalisation of the behaviour
what are closed questions
a type of question that can only be answered with a limited number of answers such as yes or no
what is concurrent validity
occurs if a test is similar to an older test that already has well established validity
what is a confounding variable
a type of extraneous variable that is related to the independent variable in the experiment
what is a control variable
any variables that are kept constant through the experiment to prevent their effects on the dependent variable
what is counterbalancing
to make half of the participants sample experience the different conditions of the experiment in one order, and the other half of the participants complete it in the opposite order
what are demand characteristics
changes in the participants behaviour to comply with the hypothesis of the researcher
what is a dependent variable
the variable that changes in response to manipulation of the researcher, that is being measured for the experiment.
what is a directional hypothesis
a hypothesis that specifies the direction of the relationship of the experiment
what is ecological validity
how well results from a test can be applied to real life
what is event sampling
an observational technique wherein an observer records every time a particular behaviour or event occurs
what is an extraneous variable
variables other than the independent variable that have an effect on the dependent variable
what is face validity
if a test appears to be valid at first appearances, in spite of how well it works in a real world scenario
what is falsifiability
the quality of being able to be proven wrong
what is generalisation
to attribute information from a sample to the rest of the population
what is a hypothesis
the prediction of the outcome of the experiment
what is an independent groups design
an experimental design where different participants are involved in different condition s of the experiment.
what is an independent variable
the variable that is manipulated by the researcher to observe its effects on the dependent variable
what is inter observer reliability
when multiple investigators gather information separately during an observation and compare their data for similarity after
what are investigation effects
unconscious changes in the investigators behaviour to comply with the hypothesis of the investigation
what is matched pairs design
an experimental design in which participants in different conditions of the experiment are matched on certain variables to reduce the effect of participant variables
what is a non directional hypothesis
a hypothesis that does not specify the direction of the relationship of the experiment
