After assessing the extent to which these techniques are currently being used in IS research, the article presents a running example which analyzes the same dataset via three very different statistical techniques.
It then compares two classes of SEM: covariance-based SEM and partial-least-squares-based SEM. tegic implications of information technology, supply chain management and business model innovations, innovation diffusion and assimilation, and organizational renewal and growth through innovations.
Because the grades on a test will vary within different age brackets, a valid instrument should control for differences and isolate true scores. External validity refers to how well your study reflects the real world and not just an artificial situation.
An instrument may work perfectly with a group of white male college students but this does not mean its results are generalizable to children, blue-collar adults or those of varied gender and ethnicity.

Finally, the article discusses linear regression models and offers guidelines as to when SEM techniques and when regression techniques should be used. In brief, a draftsinstrument was pretested with the CIO at eachsof the 21 banks within the Minneapolis-St.s Paul, Minnesota, metropolitan area to ensuresthat the instrument was valid (=-=Straub 1989-=-).s Based on informat ion prov ided bysthes American Bankers Association, each bank insthe stratified sample was called to identify thesperson who held corporate responsibility for ISsin the bank.

The article concludes with heuristics and rule of thumb thresholds to guide practice, and a discussion of the extent to which practice is in accord with these guidelines. His research in some of these areas has been funded Citation Context ...
Therefore, it is important to operationalize or define the construct precisely.
Only a few researchers have devoted serious attention to measurement issues over the last decade (e.g., Bailey and Pearson, 1983; Goodhue, 1988; Ives, et ai., 1983; Ricketts and Jenkins, 1985), and while the desirability of verifying findings through intemal validity checks has been argued by Jarvenpaa, et ai.
(1984), the primary and pdor value of instrument validation has yet to be widely recognized.
The rules may be implemented through the automated facilities of a data dictionary, or by the inclusion of explicit application program validation logic.
Rigour or rigor has a number of meanings in relation to intellectual life and discourse.
