If you plan to use an existing instrument, summarize what youhave been able to learn about the validity and reliability of results obtained with it. If you planto develop an instrument, explain how you will attempt to ensure validity and reliability. Ineither case, explain how you will obtain evidence to check validity and reliability.Problem Sheet 8Validity and Reliability1.
