Peningkatan Keakuratan Data Penelitian melalui Pengujian Instrumen dengan Metode Bivariate Pearson dan Split Half

Abstrak

A valid and reliable research instrument used in gathering research data is an instrument that has been tested for validity and reliability. Validity testing is done to see whether the questions in the research instrument are valid or biased, while the reliability test is done to see the level of reliability of the research instrument. Especially research that is a case study, collecting research data using research instruments (questionnaire or questionnaire). To assist researchers in testing research instruments, the results of this study will create a system for testing the validity and reliability of research instruments that are easy to use by researchers so that the research data to be collected is more accurate.
