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.

The best operational definition is one that has the clearest relationship to the construct definition.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.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.Your access to the NCBI website at gov has been temporarily blocked due to a possible misuse/abuse situation involving your site.

This is not an indication of a security issue such as a virus or attack.

Now that the sample has been identified, the researcher must now transition to thinking about what the variables mean both theoretically and practically to determine how to measure the key variables in the study.

Measurement consists of assigning numbers or labels to the units of analysis that accurately represent their position on the variables under study.

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.

A researcher must develop a construct definition for each key variable identified from Step 2: Identify Key Variables and Research Design.
