Table 1 Data analysis was used to obtain the empirical validity of diagnostic tests. The empirical information is the different power of the questions, the level of difficulty of the questions, and other things that affect the validity and reliability of the questions. Item validity is sought by correlating item scores with total scores (product-moment coefficients). The reliability test was carried out using the Kuder Richardson formula, which was used for objective shaped instruments with Arikunto’s scales (2002).
