Reliability and Validity Tests
A written research proposal needs to show how reliability and validity of research instruments will be tested. Whereas reliability denotes the dependability or consistency with which a test measures a given characteristic, validity refers to the extent to which a given test measures what it is actually supposed to measure. Tobit Research Consulting Limited understands the need to ensure that your data collection instruments meets the reliability and validity instruments. This is why we have been insisting on helping candidates writing research proposals or those doing business research to know how to calculate Cronbach’s alpha for assessing reliability. Cronbach’s alpha of greater than 0.7 means that a research instrument is reliable. Our professionals also help candidates determine whether their data collection instruments are consistent with the information that they want to collect. During our training on proposal development, you will be guided on how to address the issues affecting reliability and validity of research instruments.
