It can be advantageous to carry out a pilot study prior to the actual research study because: it permits a thorough check of the planned data collection and analysis procedures a pilot study involves more control over the procedures than is generally attained in the actual research project if the pilot study results are positive, further work on the research project will be unnecessary the researcher can use the results of the pilot study in the actual study, thus reducing the number of participants needed
