Quantitative research, also called "Empirical Research," refers to any research based on something that can be accurately and precisely measured. Quantitative research will include studies that have numerical data.
Qualitative research derives data from observation, interviews, or verbal interactions and focuses on the meanings and interpretations of the participants. and can be used to gain a better understanding of or a new perspective on a topic. The findings in qualitative studies are not based on measurable statistics but rather on data gathered through interviews and observation. The analysis of qualitative research is interpretative, subjective, and impressionistic.
