7.1: Observational design Flashcards
Researchers were interested in the spatial awareness skills of motorists. They decided to investigate a possible relationship between different aspects of spatial awareness. Motorists who had between ten and twelve years of driving experience and held a clean driving licence with no penalty points were asked to complete two sets of tasks.
Set 1: To follow a series of instructions and using a map, to identify various locations correctly. This provided a map reading score for each motorist with a maximum score of 20.
Set 2: To complete a series of practical driving tasks accurately. This involved tasks such as driving between cones, driving within lines and parking inside designated spaces. Each motorist was observed completing the Set 2 tasks by a single trained observer who rated each performance by giving the driver a rating out of 10.
Briefly outline one problem of using a single trained observer to rate the participants’ driving skills in the practical task. Briefly discuss how this data collection method could be modified to improve the reliability of the data collected (6 marks)
One problem of using a single trained observer to rate the participants’ driving skills in the practical task is researcher bias

One problem of using a single trained observer to rate the participants’ driving skills in the practical task is researcher bias – what?
One problem of using a single trained observer to rate the participants’ driving skills in the practical task is researcher bias – using one observer means that reliability cannot be checked

A possible modification is increasing the number of observers of the driving task, why?
A possible modification is increasing the number of observers of the driving task, because then the data is less subject to individual bias
