Methodology | Quantitative vs Qualitative | Sampling | Data Collection | Data Analysis
Choosing the right research method is like picking the perfect tool for a job—it shapes the questions you ask, the data you gather, and the conclusions you draw. Quantitative, qualitative, or mixed methods each offer unique strengths, but how do you know which is the best fit for your study? This guide will help you align your method with your research goals.
1. Quantitative research
Quantitative research is like a detective’s toolkit, turning observations into numbers and patterns. Think of a teacher tracking how often students complete homework to predict their exam success. It’s all about asking how many, how often, or to what extent, making it perfect for uncovering trends, testing theories, and making predictions with clarity and precision.

Data Collection and Analysis Methods |
|---|---|
|
🎓 Education Does using interactive digital tools improve student performance in high school math classes? |
📋 Standardized pre-and post-tests to students in classes using digital tools and traditional methods. 🔍 Test the difference between the two groups using statistical methods like t-tests or ANOVA. |
|
💊 Public health What is the correlation between daily step count and blood pressure levels in adults aged 40-60? |
📋 Collect daily step counts and measure blood pressure. 🔍 Correlational analysis to determine the strength and direction of the relationship between step count and blood pressure. |
|
💼 Business How does introducing flexible working hours affect employee productivity in a technology organization? |
📋 Track key productivity metrics (e.g., task completion) before and after implementing flexible hours. 🔍 Paired sample t-test to compare productivity metrics before and after flexible hours. |
2. Qualitative research
Qualitative research is the art of storytelling, like a journalist capturing the emotions of a community after a major event. It dives deep into human experiences, exploring the why behind decisions or the how of behaviors. Instead of numbers, it paints a vivid picture of perspectives and emotions.
