Answer 2

C. Cross-sectional, longitudinal

• Cross-sectional study is defined as an observational study where data is collected as a whole to study a population at a single point in time to examine the relationship between variables of interest.

• In an observational study, a researcher records information about the participants without changing anything or manipulating the natural environment in which they exist.
• Longitudinal study, like the cross-sectional study, is also an observational study, in which data is gathered from the same sample repeatedly over an extended period of time.
• Longitudinal study can last from a few years to even decades depending on what kind of information needs to be obtained.
• The benefit of conducting longitudinal study is that researchers can make notes of the changes, make observations and detect any changes in the characteristics of their participants.
• One of the important aspects here is that longitudinal study extends beyond a single frame in time.
• As a result, they can establish a proper sequence of the events occurred.
