Pilot Tests
Pilot tests are conducted to test the validity and the reliability indices of the instruments used especially when these instruments measure a certain psychological construct like motivation or perception or a work-related construct like job-satisfaction or performance.
Among the validity tests requiring statistical tests is the criterion-related validity which requires Pearson product moment cerrelation. To assess the internal reliability of the instrument, the Cronbach- alpha is ascertained. To determine the number of factor assessed by a certain instrument, Factor Analyses is used.
