Validating quantitative data model

Once the table of specification is completed, the researcher can write the items in the instrument.The researcher must determine the format to be used, ie. The format of the questions should be determined by the type of data that needs to be collected.To learn more or modify/prevent the use of cookies, see our Cookie Policy and Privacy Policy.

Once the items are written, they need to be reviewed for clarity, formatting, acceptable response options, and wording.The reliability coefficient can range from 0.00 to 1.00, with values of 0.70 or higher indicating acceptable reliability (George and Mallery, 2003).If the instrument is going to be used to predict future behavior, the instrument needs to be administered to the same sample at two different time periods and the responses will need to be correlated to determine if there is concurrent validity.An instrument is content valid when the items adequately reflect the process and content dimensions of the objectives of the instrument (Benson & Clark, 1982).Again, the instrument should be distributed to a sample that is representative of the target group.
