Answer The Following Questions – Assignment Example

Case a) Hypothesis Testing b) It is a case of hypothesis testing because researcher’s theory that ‘ low levels of oxygen in the mines is the single most important factor that tires the miners easily’, is an unproven statement. This statement (hypothesis) forms the basis of further research. Validity of this statement could be arrived at only by adequate research/testing.
c) Field experiment
d) Causal study
e) It is a causal study because the major objective of the research is to obtain evidence regarding cause (i.e. low levels of oxygen) and effect( i.e. tiring the miners) relationship. This could be researched only through experiment and hence, it’s a case of causal research.
f) Longitudinal design
g) Longitudinal design is preferable because it will provide a series of pictures, which when viewed together would give an in depth view of the situation (workers level of energy in controlled environment) and the changes that take place over time.
h) Individuals who are miners
i) Unit of analysis is individuals who are miners because here miner is the major entity that is being analyzed under different levels of oxygen.
Case 2:
a) Exploratory
b) The research intends to be purely for the sake of more insights and understanding. Moreover, there is no hypothesis on the basis of which relationships have to be examined. Hence, it is a case of exploratory research which has as its primary objective the provision of insights into, and comprehension of the problem situation confronting the researcher.
c) Comparative Study
d) Correlational study
e) Basic idea in this research is to understand the relationship between three variables and at this stage experiment cannot be conducted since cause and effect variables are not known.
f) Cross-sectional
g) Cross-sectional is preferable because, to measure the relationship between depreciation, assets accounting and taxes paid, the sample required should be representative and collection of data only once from a given sample of population element is sufficient.
h) Organizations
i) Unit of Analysis is Organizations because the researcher would have to analyse the asset, depreciation and tax paid of various organizations to decipher the relationship between three variables. The sample should be from various organizations because asset class/size can vary as per the industry.
Case 3:
a) Hypothesis testing
b) It is a case of hypothesis testing because the researcher wants to test whether enhanced automation technology raises the productivity of the workers in the plant or not. This statement may take the form of any type of hypothesis: directional or null
c) Comparative Study
d) Causal study
e) Since the major objective of the research is to find out if enhanced automation technology (cause) results in raising productivity of workers (effect) or not, it analyses the causal relationship between two variables and hence, is causal study.
f) Cross-sectional study
g) Since the comparison is required at the aggregate level (i.e. the group of apprentices who have been provided enhanced automation) and not at individual level, the cross-sectional study would be best for this kind of analysis.
h) Group of Apprentices
i) Unit of analysis is group of apprentices because increase in productivity of the group is the subject- matter of analysis.
