Step 3: Choose Data Collection Method(s)
How to Choose a Method
Should you use quantitative or qualitative methods?
The decision about who should answer is also tied to the decision about how it
should be answered. Your first determination should be whether to use
qualitative or quantitative methods. Qualitative methods provide rich
descriptive information and insights into characteristics and choices.
Quantitative methods provide numbers, frequencies, percentages, and rates. Both
are important and can complement each other.
