Research methods - Observations Flashcards
what kind of data does observation produce
primary data as the researcher obtains the data themselves
what may you see hypotheses referred to as
alternative hypotheses- the must be fully operationalised
define behavioural categories
the behaviours that are to be observed and recorded
what must behavioural categories be
mutually exclusive, clearly operationalised, objective and observable
where are behavioural categories noted
behavioural checklist
define the coding frame
a record of the criteria used to classify behaviours. it may include definitions of the codes used
give a weakness of behavioural categories
behaviours may be missed as behaviours are complex so not all are written down in the checklist - reduced accuracy
give a strength of behavioural categories
produces quantitative data because observers use tallies. This is easier to interpret - easily spot trends and patterns in behaviours
define event sampling
a researcher recording an event every time it happens during a specified time frame
define time sampling
a researcher observes behaviour at regular interval for a specified amount of time, over a specified period of time.
what are strengths of event sampling
it is less likely that behaviour of interest will be missed
useful when behaviours are infrequent
what are weaknesses of event sampling
may miss behaviours if too much is happening at once or researcher is fatigued
what are strengths of time sampling
reduces time spent of observation - may increase accuracy
provides insight into how much time a participant spends in a particular activity
what are weaknesses of time sampling
behaviours may be missed - reducing validity
accuracy is reduced if several participants are observed at the same time
what is a structured observation
pre-determined checklists and categories
what is a strength of structured observation
quantitative data - comparable and easy to analyse
what is a weakness of structured observation
frequencies lack meaning
what is unstructured observation
no checklist so every behaviour seen is written down in as much detail as possible
