Question No. 1.
(a) This is an analytical study. An analytical study is the one in which relationships are
used to test the hypothesis and to find out the effect of one variable on the other (Little, 2014).
Relative risk ratio is used for the types of studies in which relative risk is identified and
compared (Schnell, 2019). Comparison of the people with and without brain cancers will be
analyzed to find out the relative risk and relative risk ratio will be used for this purpose.
(b) This study is a cohort study. A cohort study is the one in which disease-free people
are taken and if they are exposed or not to the risk factors, their results are studied after a couple
of years (MacGil, 2018). A relative risk ratio is also used for a cohort study and it will be used
in this case as well. A follow up after many years is a characteristic of the cohort study.
(c)This study is ecological. An ecological study is the one in which variables are
measured at a broader group level and not at individual levels (PenState, 2019). Associations
for this study cannot be done at the individual levels. Correlation is used to find out the
relationship between these two variables. The variables are generalized and all the research is
done at the macro level in which no individuals are studied but research is done at the national
level.
(d)This study is descriptive. In descriptive research design, researchers try to find out a
relationship between an ailment and its reason (Explorable, 2019). Correlational research can
be done to find out the relation between the two variables and to find out any association
between them (Lumen, 2019). To know the relationship between the two variables Ascaris
lumbricoides and household reach to tap water, the correlational analysis will be made.

Question No. 2.
(a)This study design is the observational study design. In observational study designs, no
interventions are considered by the researcher and he observes the changes and the differences
that occur (Sauro, 2015). In this study, an observation was made on the risk factors and the
development of cancer among the workers in an asbestos manufacturing facility and the
telephone repairmen services. This study was a Retrospective Cohort-observational research
study because over thirty years, follow-up research was done to know the effects on the
development of cancer. All people in that cohort were free of cancer initially and after 30 years,
a few of them developed cancer.
(b)This study design is the observational one in which the researcher wants to do a cross-
sectional study. A cross-sectional study design is the one in which the researcher wants to study
the outcomes of the disease (Cherry, 2019). The researcher does not alter the results of the
research and collects the facts and figures to make the research authentic, reliable and valid. In
this study, the researcher wants to find out the reasons why kids get jaundice and she also
selected those kids who were newly born, to get the accurate results whether or not there were
any associations between the infections being transferred from the mothers. This cross-sectional
study is used to know the risk factors and the association of these variables to some independent
variables. In this research, the reliability and validity of the results can be checked if there is any
possibility to construct relationships between the occurrence of jaundice and the records taken
from the mothers of those kids.
(c)This study is an experimental one because, in this study, the effects of the medicine
erythromycin are being studied whether they cause any negative effects on the health of the
