L. Validity

To validate the data the researcher will use triangulation . Triangulation is qualitative cross-validation. It assesses the sufficiency of the data according to the convergence of multiple data sources of multiple data collection procedures. Thereby, there is a triangulation of sources, triangulation of data collection techniques, and time. Triangulation of sources to test the credibility of the data is done by checking the data that has been obtained through several sources. Triangulation techniques to test the credibility of the data is done by checking the data to the same source with different techniques. Time is also often affects the credibility of the data.
