Research scenario 1: In a study looking at
undergraduate students' perceptions of sense of
community at their university, a researcher
hypothesizes that the farther away students live
from campus (in miles), the less they feel they
are part of the university community. The
researcher collected data for the following two
variables – miles from campus and part of
community (continuous rating scale from 1-10 of
how much they felt part of the university
community).
Which of the following research ideas will be best for using a cross-
sectional research design?
To see the effect of access te fast internet on academic performance of school
children.
O
To see the prevalence of fast internet users among private university students.
To see the academic outcome of online teaching verses face to face teaching
To see health outcome of eating organic food versus genetically modified food.
If a researcher wishes to see the effect of an intervention, which of the
following would be the research design of choice?
O Experimental study
Observational study
Qualitative study
O Mixed methods
Recent research indicates that the effectiveness of antidepressant medication is directly related to the severity of the depression (Khan, Brodhead, Kolts & Brown, 2005). Based on pretreatment depression scores, patients were divided into four groups based on their level of depression. After receiving the antidepressant medication, depression scores were measured again and the amount of improvement was recorded for each patient. The following data are similar to the results of the study.
