Pilot study

SPECIFIC OBJECTIVESAt the end of this micro teaching student will be able to:-Define pilot study.Describe the objective of pilot study.Explain the purpose of pilot studyDiscuss the reason for pilot studySpecify the selection criteria

Enumerate the factor help in determining the sizeDescribe the advantages and disadvantages of pilot study.Enlist the limitation of the pilot study.DEFINITIONA 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 toolCollecting of dataProcessing and analysis of dataReport writing

OBJECTIVEThe 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.

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

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.

REASONSA pilot study is conducted to pretest a newly designed instruction.

SELECTION OF PEOPLE FOR PILOT STUDYThe people are selected for the pilot study who are similar in characteristics to the sample that will used for the actual study.

Factors help in determining the size of pilot studyFUNCTIONSAdequacy of the study method.

Appropriateness and quality of instruments.

Strength of relationship between key variable.

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.

ADVANTAGES

It tells about the completeness, accuracy and convenience of the sampling frame from which it is proposed to select the sample.It unfold the variability within the population to the surveyed/studies.Importance in determining the size of the sample.It helps in bringing out the inadequacy of the draft questionnaire. It throws light on the several difficulties.It tests interviewer stamina to work under condition of personal discomfort, stress and fatigue.It helps in identifying the need for different kinds of equipment and vehicles, which are necessary during project.

DISADVANTAGESPilot study research design is structured study; the structured study introduces biases into the result of the study to prove exactly what the researchers wanted to show.The sample of the study is not randomly selected.The treatment of subjects does not reflect, and is usually modified to favor the result that the researcher required.

LIMITATIONA 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.
