Which of the following is a research method?

• Correlation

• Matched-pairs

• Randomization

• Brain Imaging

This research method is a descriptive technique in which one individual or group is studied in depth in the hope of revealing universal principles

• Case Study
• Survey
• Observational
• Correlational
• Experiments

This is a method of research where the researcher carefully and systematically observes and records behavior without interfering

• Observational
• Correlational
• Experiments
• Case Study
• Survey

This research method is a measure of the extent to which two variables change together, and thus of how well either variable predicts the other

• Correlational
• Experiments
• Case Study
• Survey
• Observational
