What does quantitative measurement use to gather data?

  1. Visual observations and anecdotal records

  2. A standardized instrument with limited response options

  3. Interviews and open-ended questions

  4. Subjective interpretations from educators

The correct answer is: A standardized instrument with limited response options

Quantitative measurement is grounded in the use of standardized instruments that allow for precise data collection through limited response options. This approach enables the gathering of numerical data that can be analyzed statistically. The use of standardized instruments ensures consistency in how data is collected across different individuals or groups, making it possible to compare results and draw objective conclusions. In contrast, visual observations and anecdotal records tend to capture qualitative data, focusing on descriptive accounts rather than numbers. Similarly, interviews and open-ended questions produce qualitative information, yielding insights through detailed narratives rather than concrete metrics. Lastly, subjective interpretations from educators can introduce personal biases and varying perspectives, further distancing the data from the objective nature required in quantitative measurement. Therefore, the method that best aligns with quantitative measurement is the use of a standardized instrument with limited response options.
