These website are what I considered good because they are always up to date and the source of information can be trusted.
Key Elements of an Effective Website
1. Appearance
2. Content
3. Functionality
4. Website Usability
5. Search Engine Optimization
Appearance
A site must be visually appealing, polished and professional. Remember, it's reflecting your company, your products and your services. Your website may be the first, and only, impression a potential customer receives of your company.
Content
Along with style, your site must have substance. Remember that your audience is looking for information that will help them make a decision, so it should be informative and relevant. Use this opportunity to increase visitor confidence in your company's knowledge and competence.
Functionality
Every component of your site should work quickly and correctly. Broken or poorly constructed components will only leave your visitors frustrated and disillusioned with your company. Across the spectrum, everything should work as expected, including hyperlinks, contact forms, site search, event registration, and so on.
Usability
A critical, but often overlooked component of a successful website is its degree of usability. Your site must be easy to read, navigate, and understand.Search Engine Optimized (SEO)
There are hundreds of rules and guidelines for effective search engine optimization, and this isn't the place to cover them all. For starters, follow these simple rules:
- Include plenty of written content in HTML format. Don't use Flash, JavaScript or image-only objects for your navigational items.
- Use your important keywords frequently and appropriately in your copy.
- Minimize the use of tables and use Cascading Style Sheets for layout and positioning; keep your HTML code clutter-free.
- Leverage your links -- make them descriptive and use your keywords in the link text
Evaluation of Web documents
1. Accuracy of Web Documents
- Who wrote the page and can you contact him or her?
- What is the purpose of the document and why was it produced?
- Is this person qualified to write this document?
- Make sure author provides e-mail or a contact address/phone number.
- Know the distinction between author and Webmaster.
- Who published the document and is it separate from the "Webmaster?"
- Check the domain of the document, what institution publishes this document?
- Does the publisher list his or her qualifications?
- What credentials are listed for the authors)?
- Where is the document published? Check URL domain.
3. Objectivity of Web Documents
- What goals/objectives does this page meet?
- How detailed is the information?
- What opinions (if any) are expressed by the author?
- Determine if page is a mask for advertising; if so information might be biased.
- View any Web page as you would an infommercial on television. Ask yourself why was this written and for whom?
4. Currency of Web Documents
- When was it produced?
- When was it updated'
- How up-to-date are the links (if any)?
- How many dead links are on the page?
- Are the links current or updated regularly?
- Is the information on the page outdated?
5. Coverage of the Web Documents
- Are the links (if any) evaluated and do they complement the documents' theme?
- Is it all images or a balance of text and images?
- Is the information presented cited correctly?
- If page requires special software to view the information, how much are you missing if you don't have the software?
- Is it free or is there a fee, to obtain the information?
- Is there an option for text only, or frames, or a suggested browser for better viewing?
Putting it all together
- Accuracy. If your page lists the author and institution that published the page and provides a way of contacting him/her and . . .
- Authority. If your page lists the author credentials and its domain is preferred (.edu, .gov, .org, or .net), and, . .
- Objectivity. If your page provides accurate information with limited advertising and it is objective in presenting the information, and . . .
- Currency. If your page is current and updated regularly (as stated on the page) and the links (if any) are also up-to-date, and . . .
- Coverage. If you can view the information properly--not limited to fees, browser technology, or software requirement, then . . .
You may have a Web page that could be of value to your research!
Example of bias information:
Global warming
Information bias
is a type of cognitive bias, and involves e.g. distorted evaluation of information. Information bias occurs due to people's curiosity and confusion of goals when trying to choose a course of action.
Over-evaluation of information
An example of information bias is believing that the more information that can be acquired to make a decision, the better, even if that extra information is irrelevant for the decision.
Examples of information bias are prevalent in medical diagnosis. Subjects in experiments concerning medical diagnostic problems show an information bias in which they seek information that is unnecessary in deciding the course of treatment.
Globoma experiment
In an experiment, subjects considered this diagnostic problem involving fictitious diseases:
A female patient is presenting symptoms and a history which both suggest a diagnosis of globoma, with about 80% probability. If it isn't globoma, it's either popitis or flapemia. Each disease has its own treatment which is ineffective against the other two diseases. A test called the ET scan would certainly yield a positive result if the patient had popitis, and a negative result if she has flapemia. If the patient has globoma, a positive and negative result are equally likely. If the ET scan was the only test you could do, should you do it? Why or why not?
Many subjects answered that they would conduct the ET scan even if it were costly, and even if it were the only test that could be done. However, the test in question does not affect the course of action as to what treatment should be done. Because the probability of globoma is so high with a probability of 80%, the patient would be treated for globoma no matter what the test says. Globoma is the most probable disease before or after the ET scan.
In this example, we can calculate the value of the ET scan. Out of 100 patients, a total of 80 people will have globoma regardless of whether the ET scan is positive or negative. Since it is equally likely for a patient with globoma to have a positive or negative ET scan result, 40 people will have a positive ET scan and 40 people will have a negative ET scan, which totals to 80 people having globoma. This means that a total of 20 people will have either popitis or flapemia regardless of the result of the ET scan. The number of patients with globoma will always be greater than the number of patients with popitis or flapemia in either case of a positive or negative ET scan so the ET scan is useless in determining what disease to treat. The ET scan will indicate that globoma should be treated regardless of the result.
