This step is helpful in developing the instrument for two reasons.
The second step in measurement is to develop a construct definition of each of the key variables.
It is very important that the instrument has been thoroughly critiqued, evaluated, and pilot tested by the student, supervisor, and others before it is administered for the actual study.
When designing an instrument, keep in mind the following: Developing an instrument takes a lot of work and advanced preparation.Any problems with the instrument after it has been administered will require the student to completely redo the data collection process, wasting considerable time and money.Therefore, researchers must take great thought and care when developing their instrument.As can be seen from the figure above, once the research design has been determined, then the researcher has two separate responsibilities: identifying the sample and determining how the key variables will be measured.The key variables should have been identified in Step 2: Identify Key Variables and Research Design.
