Describe the characteristics, strengths, weaknesses, and kinds of quantitative research; 2. Illustrate the importance of quantitative research across fields; 3. Differentiate the kinds of variables and their uses.
Understand the Problem
The question is asking for detailed descriptions and illustrations related to quantitative research, including its characteristics, strengths and weaknesses, its importance across different fields, and an explanation of the different types of variables and their uses.
Answer
1. Quantitative research is systematic, involving numerical data and statistical analysis. 2. It's vital across fields for objectivity and data-driven decisions. 3. Variables include independent, dependent, control, and extraneous.
- Quantitative research is characterized by its objective nature, involving structured instruments and numerical data to perform statistical analysis. Its strengths include precision, reliability, and the ability to generalize findings. Weaknesses include potential lack of depth and the risk of overlooking context. Types include descriptive, correlational, causal-comparative, and experimental research. 2. Quantitative research is crucial across fields as it provides measurable data that can inform decision-making, policy development, and hypothesis testing. It enhances objectivity in fields like social sciences, health, and business. 3. Variables in quantitative research can be classified as independent, dependent, control, and extraneous. Independent variables are manipulated, dependent variables are measured, control variables remain constant, and extraneous variables are those that should be controlled or accounted for but are not directly of interest.

More Information
Quantitative research is critical due to its capacity to process large sample sizes objectively, allowing for broad data generalization while maintaining replicable results.
Tips
A common mistake is confusing qualitative and quantitative methods, where the former focuses on understanding meanings and experiences rather than measuring numerically.
