Observational Design Flashcards
What is an observational design?
The choice of the behaviour to record and how they are measured
What are behaviour categories?
-Operationlised behaviours that the observer will be looking for
-The researchers will agree on the behaviours that should be recorded, creating these behaviour categories
-The behaviour categories need to be able to reflect what is being studied, and then the researcher would develop codes for behaviours relevant to that
What are sampling procedures?
-Can be difficult to observe all behaviour at all times during an observation especially if a continuous observation
-Researchers use a sampling procedure to help this, such as time sampling and event sampling
What is time sampling?
The researcher records all behaviours for a set time frame, at a set point.
-The researcher would choose the time sample relevant to the research
-Time sampling allows the researcher flexibility to record behaviour and has the opportunity to record unexpected behaviours
-However, it can also miss behaviours that do not happen within the set time
What is event sampling?
-The researcher records/tallies every time a behaviour (from the behaviour categories) happens
-The researcher observes these behaviours on target individuals
-All behaviours that are included in the behaviour categories are on a list then that behaviour will be recorded
-However, behaviours that are not on the categorised list are not recorded, which means relevant behaviours could be missed
What is inter-observer reliability?
-level of consistency between 2 or more trained observers when they conduct the same observation
-Inter-observer reliability means it is less like to have observer bias and therefore, can be a valid representation of behaviour
-A high correlation coefficient shows the behavioural categories are reliable
What are the steps of inter-observer reliability?
-They must agree on the list of behaviour categories and how they are going to record them before the observation begins
-The observation is conducted separately by each observer
-They then compare the two independent data sets and test the correlation using a statistical test (e.g. Spearman’s Rho)
This produces a correlation coefficient result (e.g., 0.63)
-To be considered a good/high level of inter-rater reliability, it must pass a threshold of +0.8 or 80% consistency
