Quantitative research objectively measures psychological phenomena to enable statistical analysis, reducing phenomena to numerical values, and applying statistical operations to these to test hypotheses.
Qualitative research attempts to be as objective as possible and to control experimental conditions.
For example, a researcher might interview the survivors of a mass shooting event by asking them to rank their feelings of anxiety using a pre-determined scale.
A research applies their own analytical model to data that has already been collected. They attempt to answer a new question or discover a new trend by looking at data.
Participants are asked a standard set of questions. These questions may be delivered in writing or through an interview format.
Applied and Field Research
When using applied research, researchers are trying to find a solution to an immediate, practical problem.
Examples include reducing drug use or improving worker happiness.
Field research is a type of applied research that is undertaken in a non-laboratory setting. These settings may include a hospital or workplace.
Research conducted in a controlled environment. These students help scholars in the field to learn more about psychological processes such as cognition or emotional development.
The design of the study refers to the means by which the research question will be addressed, specifically in relation to the data that will be collected, the comparison that will be made, the experimental conditions (if any) that will be manipulated, and so on.
If s study is poorly designed in the first place, there it many never be possible to meaningful interpret the data which result from it.
|Finding can be generalized to the population at large|
|Samples can be selected to ensure the results are representative|
|Estimates can be obtained as to the magnitude and distribution of impacts|
Clear documentation can be provided
|Control for extraneous variables|
|Many times of information may be difficult to obtain through data collection instruments|
|Many groups may be difficult to satisfactorily represent|
|Self-reporting may be inaccurate|
|No information regarding contextual factors|
|Unnatural situations may alienate respondents|
|Research methods are inflexible|
