What is the best way to check the reliability and validity of a resource?
Answers
Answer:
· The best way to check the validity and reliability of a resource is by analyzing the author's education and professional background.
Explanation:
Once you’ve been to the library and checked out books, copied articles, and printed information from Web sites, you have to decide which sources to use. Your teacher might require that you use a certain number of sources of a certain type (for example, one book, two articles, and one Web site). Regardless, it is important that you use a variety of sources to avoid relying too much on one source. You might wonder why using one good source would be a problem, especially if it is the best one to support your thesis. If you just use one source or rely too heavily on one source, then your paper will turn into a summary of that author’s ideas about the subject instead of containing your own ideas.
Why is it important to determine whether your source is reliable? Just as the quality of research in student papers varies, so does the quality of information in many sources. Let’s take newspapers, for example. Tabloids that report mostly celebrity news and gossip and that have a reputation for being sued for publishing inaccurate information are not reliable sources, but newspapers such as the New York Times and the Houston Chronicle are considered valid and reliable sources. While they sometimes make mistakes in their reporting, those mistakes are usually minor, and they’re corrected as soon as they are discovered. Articles full of inaccuracies are rare in those newspapers.
This lesson will help you decide what sources are valid and reliable for supporting a thesis.
There are different validity and they can be determined by the following tests:
1) Convergent Validity (within larger Construct Validity) - refers to indicators / questionnaire items of a specific construct / variable are converging towards / loading a large portion of the variance that is in common (there are several ways to measure convergent validity, 1 of them is to check Average Variance Extracted (AVE) 0.5 (Hair et al., 1998)
2) Discriminant Validity (within larger Construct Validity) - refers to indicators / questionnaire items within a construct / variable are strongly associated with each other, but are distinctly from other constructs / variables' indicators / questionnaire items (to determine there is discriminant validity, square roots of AVEs should be higher than the correlations between constructs / variables)
3) Content Validity - refers to what extent the measurement is representing the content (this can be determined by panel of judges' opinions)
4) Face Validity - can be determined by basic walk through the questionnaire items whether they are intended to measure a concept
5) Concurrent Validity (within larger Criterion Validity) - refers to the questionnaire's capability that can differentiate respondents who are known to be different e.g. Theory-X vs Theory-Y workers (to determine concurrent validity, check the scores from different groups of respondents in which they should scored differently)
6) Predictive Validity (within larger Criterion Validity) - refers to the questionnaire's capability to differentiate respondents with reference to future criterion e.g. interview's aptitude test predicting future job performance (this can be determined by by checking the scores of good vs poor performers which should be different)

Validity and reliability of a resource are the most important aspects to be considered in developing any instrument.
Explanation:
- Validity commonly refers to the degree of accuracy of measurement which the developing instrument intends to measure while reliablity refers to degree the instrument provides consistent results.
- The former includes content,construct and criterion related checking that holds importance in reviewing by a subject expert who produces a distinct observation.Meanwhile the criterion based checking refers to the score that correlates with the external criterion.
- The later includes internal consistency,test-retest and inter-rated checking measures.
- It is important to develop a reliable and valid resource which further requires multiple steps of iterations of piloting and also testing.
