Chapter 4: Results and Discussion of Quantitative Research


In quantitative research, chapter 4, commonly known as the Results and Discussion chapter, provides a detailed analysis of the data collected during the study. This chapter plays a crucial role in presenting and interpreting the findings to answer the research questions or test the hypotheses. This article will provide a sample structure and content guidelines for a chapter 4 of a quantitative research study, focusing on the discussion of the results.

Data Analysis and Findings

The data analysis phase involves processing and summarizing the collected data. Commonly used statistical methods, such as descriptive statistics, inferential statistics, and regression analysis, are implemented to analyze the data and obtain meaningful results. In this section, we provide an example of how the results and findings could be presented for a quantitative research study on the impact of physical activity on overweight prevalence among adolescents.

Descriptive Statistics

Descriptive statistics are used to summarize and describe the characteristics of the variables under investigation. For instance, in our study, we collected data on age, gender, body mass index (BMI), and frequency of physical activity. The descriptive statistics section would present the mean, standard deviation, range, and frequencies of these variables. These statistics provide an overall summary of the sample and assist in understanding the demographic details and characteristics of the participants.

Inferential Statistics

Inferential statistics allow researchers to make generalizations about the population based on the collected sample data. This section typically includes information on hypothesis testing and statistical tests conducted to determine whether there are significant differences or relationships between variables. For example, we could use a chi-square test to assess the association between physical activity and overweight prevalence. The findings would be presented, including the test statistic, degrees of freedom, p-value, and interpretation of the results. Additionally, other statistical tests, such as t-tests or ANOVA, can be used to compare means or investigate differences among groups, based on the nature of the study.

Regression Analysis

Regression analysis is used to explore the relationships between variables and assess their impact on the dependent variable. In our study, we could perform multiple regression analysis to examine the influence of age, gender, and physical activity frequency on BMI. The results of the regression analysis would be presented, including the beta coefficients, standard errors, p-values, and interpretation of the findings. This analysis enables researchers to determine the significance and magnitude of the relationship between the variables under investigation.

Discussion of Results

After presenting the results, the discussion section offers an opportunity to interpret and explain the findings in light of the research questions or hypotheses. It requires a comprehensive analysis of the results and should demonstrate a clear understanding of the implications and relevance of the findings. Here are some sample content guidelines for the discussion section:

1. Interpretation of Findings: Start by summarizing the key findings corresponding to each research question or hypothesis. Ensure clarity and avoid overly technical details. Explain the relationships, differences, or associations identified through statistical analysis.

2. Comparison with Previous Studies: Discuss how your findings align or differ with previous research in the field. Analyze any discrepancies or consistencies with the existing literature and provide possible explanations for why these differences may have occurred.

3. Implications and Significance: Evaluate the implications of your findings to the field of study or society as a whole. Discuss how the results contribute to the existing knowledge or fill gaps in the literature. Highlight any practical applications or policy recommendations that can be derived from your research.

4. Limitations and Future Directions: Acknowledge any limitations or shortcomings of your study. Identify potential sources of bias, sample size constraints, or methodological issues that could have influenced the results. Suggest areas for future research that could build upon your study to address these limitations.


Chapter 4: Results and Discussion of a quantitative research study is crucial in presenting and interpreting the obtained findings. By utilizing various statistical analysis methods, researchers can effectively summarize, interpret, and discuss their results. The discussion section allows for a comprehensive analysis of the findings and connects them to the existing literature, offering an opportunity to contribute to the field and suggest future research directions.
