The website I commonly use is www.instructables.com. This is a Do-It-Yourself instructions website that teaches or shows innovators what to do in order to come up with something unique by using various easy to find materials. The items made, taught and displayed on the website range from recipes to robots. The general structure of every article is a title, list of components needed to come up with the item listed in the title, the general assembly or way to mix the components, arrange them and the workability of the final product.
The website’s different articles are authored by different writers with different professionalism. Their expertise in what they present to the website is well demonstrated by the eventuality of the project. Their validity in the truth of the content presented is also shown by the description of the final product and its functionality particularly with regard to an engineering project. No one really knows the authors as they may choose to have nicknames and have their information hidden from readers.
The reliability of the information in the website is rather high since the projects presented in the website need to work, for a writer’s profile to remain legit. Also, posting the article on instructubles welcomes anyone and everyone from the world over to build, test and give feedback on the products you show people how to make. Having invalid or misleading information could result in article removal.
Some of the reliability tests include the test and re-test reliability test which is able to indicate the repeatability of test scores over a period of time. This reflects the stability of the system or construct. Alternate or parallel form tests the consistency of expected results when done by different people more than once. Inter-rater reliability tests the consistency of test scores when rated by two or more raters (U.S Department of Labor, 1999).
