Question

1. Many were concerned about the operation of the infamous BCCI, the international banking institution. If the government had desired to probe into the details, would this investigation have called for: a) A causal or correlational study? Why? b) A exploratory, descriptive, or hypothesis‐testing study or case analysis? Why? c) A field study, lab experiment, or field experiment? Why? d) A cross‐sectional or longitudinal study? Why?

Answer 1

A) The governmant can conduct Casual study if they need to probe into the details of BCCI (international banking institution). The investigation into an issue or topic that looks at the effect of one thing or variable on another. explanatory research or casual research dealt with the investigation of cause-and-effect relationship determine causality, it is important to observe variation in the variable assumed to cause the change in the other variable(s), and then measure the changes in the other variable.Corrrelation method is not appropriate for the study, because it deals with revealing the cost and effect relationship between two variqables.

B) The explanatory case study focuses on an explanation for a question .The primary purpose of the research is to explain why phenom- ena occur and to predict future occurrences. these are characterized by research hypotheses that specify the nature and direction of the relationships between or among variables being studied. Exploratory-descriptive designs, usually field studies in natural settings, provide the least control over variables.An exploratory case study is usually the precursor to a formal, large-scale research project.it is also known as discriptive and hypothesis testing. Hypothesis testing is used to assess the plausibility of a hypothesis by using sample data.he primary purpose of the research is to explain why phenom- ena occur and to predict future occurrences.

C) Here field experiment is said to be the best for data analysis. Field experiments are studies using the design that occur in a natural setting. Researchers examine how the manipulation of at least one independent variable leads to a change in a dependent variable in the context of the natural environment. Field experiments encompass a broad array of experimental designs, each with varying degrees of generality. The generality refer to the contextual similarities between the subjects in the experimental sample.

D) Cross sectional study can be conducted for resaeching about BCCI. it is a type of observational research that analyzes data of variables collected at one given point in time across a sample population or a pre-defined subset. cross sectional study is also known as transverse study, or prevalence study . This means that researchers record information about their subjects without manipulating the study environment . The benefit of a cross-sectional study design is that it allows researchers to compare many different variables at the same time. .thus is used to assess the burden of disease or health needs of a population and are particularly useful in informing the planning and allocation of health resources. the survey may be purely descriptive and used to assess the burden of a particular disease in a defined population.
