What type of research is based on measurable data such as test scores?

Quantitative research is focused on collecting and analyzing measurable data, which is often expressed in numerical form. This type of research emphasizes objectivity and the use of statistical methods to derive meaningful conclusions. Test scores are a prime example of measurable data, as they can be quantified and analyzed to identify patterns, correlations, or differences among groups.

In quantitative research, researchers often use tools like surveys, experiments, or existing records to gather numerical data, which allows for precise comparisons and often leads to generalizable findings. This approach is particularly useful in educational settings where performance metrics, such as test scores, play a critical role in assessing student achievement and program effectiveness.

The other types of research mentioned do not focus on measurable data in the same way. For instance, qualitative research typically explores subjective experiences and opinions rather than quantifiable outcomes. Reflective practice research involves the personal insights and reflections of educators, emphasizing self-assessment and professional growth rather than numerical data. Simple descriptive research may involve data collection but does not delve deeply into statistical analysis or the rigor typically associated with quantitative methods.
