Quantitative Data Analysis

In quantitative data analysis you are expected to turn raw numbers into meaningful data through the application of rational and critical thinking. The same figure within data set can be interpreted in many different ways; therefore it is important to apply fair and careful judgement.


For example, questionnaire findings of a research titled “A study into the impacts of informal management-employee communication on the levels of employee motivation: a case study of Agro Bravo Enterprise” may indicate that the majority 52% of respondents assess communication skills of their immediate supervisors as inadequate.


This specific piece of primary data findings needs to be critically analyzed and objectively interpreted through comparing it to other findings within the framework of the same research such as organizational culture of Agro Bravo Enterprise, leadership styles exercised, the levels of frequency of management-employee communications etc.


Moreover, literature review findings conducted at the earlier stages of the research process need to be referred to in order to reflect the viewpoints of other authors regarding the causes of employee dissatisfaction with management communication and integrating secondary data within discussions and analyses in a logical and unbiased manner.


Let’s take another example. A dissertation exploring the impacts of foreign direct investment (FDI) on the levels of economic growth in Vietnam for a specific period of time with the use of correlation method, where FDI and GDP have been specified as the two variables produces a correlation coefficient of 0.9.


In this case simply stating that there is a strong positive correlation between FDI and GDP would not suffice; you have to provide explanation about the manners in which the growth on the levels of FDI may contribute to the growth of GDP by referring to the findings of the literature review and applying your own critical and rational reasoning skills.
