7. Types of
Longitudina
l Studies
•Trend Studies
•Cohort Analysis
•Panel Study

8. Trend
Studies:
•A most common type of Longitudinal
Study in mass media Research.
•Trend Study samples different
groups of people at different times
from the same population.
•Trend Studies are common
around presidential election
time.

10. Cohort
Analysis:
•A cohort is any group of individuals who
are linked in some way or who have
experienced the same significant life event
within a given period.
•Any study in which some characteristic of
one or more cohorts is measured at two or
more points in time is a Cohort Analysis.

12. Panel
Studies:
• Panel Studies measure the same sample of
respondents at different points in time.
• Unlike Trend Studies, panel studies can reveal
information about both net change and gross
change in the dependent Variable.

14. Combining
Qualitative &
Quantitative Data in
Longitudinal
Research

15. Advantage
s:
•The qualitative data can aid in the
interpretation of the quantitative data and
provide insights that might have been missed.
•Qualitative data might suggest new hypotheses
that could be examined in subsequent waves of
data collection.

16. Longitudinal Research
on the Internet:
An internet survey panel consists of individuals who have
been prerecruited to participate in a number of surveys
over time.
Advantages: A large number of individuals can be
recruited to serve as potential panel members. This makes
it easier for researchers to target and collect data from low-
incidence groups.
Disadvantages: Internet panels may not be
representative of the entire population. Not everyone is
skilled at completing online surveys.
