Several kinds of experimental designs exist. In general, designs that are true experiments contain three key features: independent and dependent variables, pretesting and posttesting, and experimental and control groups. In a true experiment, the effect of an intervention is tested by comparing two groups.
Q. What is the general purpose for using simulations and field studies quizlet?
Simulation and field studies are used to increase the external validity of experiments. Simulation involves bringing aspects of the real world into the laboratory.

Q. What is the advantage of field study over a laboratory study?
Strength: behavior in a field experiment is more likely to reflect real life because of its natural setting, i.e. higher ecological validity than a lab experiment. Strength: There is less likelihood of demand characteristics affecting the results, as participants may not know they are being studied.
Q. What research attempts to identify the active components of the treatment?
Process research
Q. What increases external validity?
How can we improve external validity? One way, based on the sampling model, suggests that you do a good job of drawing a sample from a population. That is, your external validity (ability to generalize) will be stronger the more you replicate your study.
Q. What is the validity of a study?
The validity of a research study refers to how well the results among the study participants represent true findings among similar individuals outside the study. This concept of validity applies to all types of clinical studies, including those about prevalence, associations, interventions, and diagnosis.
Q. What is validity and its types?
The four types of validity. Construct validity: Does the test measure the concept that it’s intended to measure? Content validity: Is the test fully representative of what it aims to measure? Face validity: Does the content of the test appear to be suitable to its aims?
Q. Is qualitative data reliable or valid?
Reliability in qualitative research refers to the stability of responses to multiple coders of data sets. It can be enhanced by detailed field notes by using recording devices and by transcribing the digital files. However, validity in qualitative research might have different terms than in quantitative research.
Q. What is the limitation of qualitative research?
The main drawback of qualitative research is that the process is time-consuming. Another problem is that the interpretations are limited. Personal experience and knowledge influence observations and conclusions. Thus, a qualitative research might take several weeks or months.
Q. What are the strengths and limitation of qualitative research?
Qualitative method
| Strengths | Limitations |
|---|---|
| Provide more detailed information to explain complex issues | More difficult to analyse; don’t fit neatly in standard categories |
| Multiple methods for gathering data on sensitive subjects | Data collection is usually time consuming |
| Data collection is usually cost efficient |
