  5. 5. DEFINITION “A pilot study is a small scale trial run of the actual research project. It is the rehearsal of the main study. It covers the entire process of the research”:- – Preparation of a broad plan of the study. – Construction of tool – Collecting of data – Processing and analysis of data – Report writing
  6. 6. OBJECTIVE • The primary objective of the pilot study is to test as many elements of the research proposal as possible, in order to correct any part that does not work well.
  7. 7. A pilot study fulfils one or more of the following purposes:- • To prevent an expensive study • To prevent misfortune of undertaking a costly large scale study
  8. 8. CONTI…. • It provides guidance on conceptualization-identification and operationalization of concepts related to study. • It assists in discovering the nature of relationship between variable and in formulating hypothesis. • It assists in developing better approaches to target population – as regards introduction, rapport etc.
  9. 9. REASONS • A pilot study is conducted to pretest a newly designed instruction.
  10. 10. SELECTION OF PEOPLE FOR PILOT STUDY • The people are selected for the pilot study who are similar in characteristics to the sample that will used for the actual study.
  11. 11. •Factors help in determining the size of pilot study
  12. 12. FUNCTIONS • Adequacy of the study method. • Appropriateness and quality of instruments. • Strength of relationship between key variable.
  13. 13. • Identification of the confounding variable that need to be controlled. • Adequacy of material for research staff. • Potential problem such as loss of participant during the course of the study.

  17. 17. LIMITATION • A pilot study is not a hypothesis testing study. • Safety, efficacy and effectiveness are not evaluated in a pilot study. • Feasibility result does not necessarily generalized beyond the inclusion and exclusion criteria of pilot design.
