What type of data would a researcher collect to quantify results?

• A. Descriptive or observational data
• B. Numerical data that can be measured or counted
• C. Data that relies on subjective interpretation
• D. Visual data from graphs and charts only

Answer: (B)

Quantifying results in research refers to the process of measuring and expressing data in numerical terms, allowing for analysis and comparison. Numerical data that can be measured or counted provides clear, objective figures such as counts, dimensions, and statistics, which are essential for analyzing relationships, trends, and differences among variables. This type of data enables researchers to apply mathematical and statistical methods, which can enhance the reliability and validity of their findings. For example, if a researcher were to measure the heights of plants treated with different fertilizers, the numerical height measurements would provide quantifiable results that can be statistically analyzed to determine the effectiveness of each fertilizer. The other types of data mentioned do not provide the same level of quantification or objectivity. Descriptive or observational data typically involves qualitative assessments that can describe characteristics but do not yield numerical values. Subjective interpretation relies on personal opinions or observations, which can vary from person to person and is not measurably objective. Visual data from graphs and charts, while informative, serves primarily to represent numerical data rather than serving as quantifiable data in itself.
