Answer to Question 1

An operational definition is one that defines a construct in terms of the operations that researchers must perform in order to measure the construct. They are important because they specify observable events that represent abstract constructs and thus make research on the construct possible.

Answer to Question 2

Mixed methods research combines both quantitative and qualitative approaches within a single study. It has the advantages of each approach and may result in findings that are more dependable and complete than either method alone could provide.
