QUANTITATIVE DATA ANALYSIS METHODS

Introduction
The quantitative data analysis methods is very important in research to achieve the
research objectives. Quantitative data analysis uses raw numbers collected either from a
survey that is primary data or from authentic journals and government data that is secondary
data or both the primary and secondary data. These are used in the analysis to find the
evidence to support or reject the hypothesis formed to attain the research objectives. To
evaluate the quantitative analysis methods, two articles are selected on brands in business
context which has used the quantitative methodology. The name of the articles are mentioned
below:
 Article 1: “Impact of Consumer’s Loyalty and Attachment o Brand Equity (A of
Beverage Sector of Pakistan)”
 Article 2: “Impact of Brand Awareness and Loyalty on Brand Equity”
Sample Size
The proper way to choose a sample size is to follow the standard equation of
necessary sample size which is mentioned below:
Necessary Sample ¿ ( Z−score )2∗( Standard Deviation )∗( 1−Standard Deviation )
( Margin of error )2
Here, Z-score is chosen on the basis of selection of confidence interval or the
significance level at which the researcher want to be confident about the results. The safe
decision about standard deviation is to use 0.5 as this ensures that the sample will be large
enough and a larger sample provides better results (Chow et al., 2017).
Article 1: This article collects data by taking responses from 200 respondent on a
questionnaire prepared on the basis of literature review of the study. The data is wide and it is
collected explicitly. The paper is discussing the results on 95% and 99% confidence interval
