Discuss your experience writing and administering the scale

Assignment: Need a discussion post and a response to a colleague post.

If you ask a classmate questions about course content and he is correct sometimes but at other times he gives you the wrong information, you might say that he is not reliable. You may want to request help from someone who knows the correct answer every time-perhaps your Instructor! The concept is the same in research. It is important to be confident that when you measure a variable repeatedly, it will have the same result. That is what reliability means in research.

Another important concept in research is validity. You might have a friend who laughs at all of your jokes. You determine that you must be very funny because your friend laughs. You are measuring your ability to be funny based on laughing behavior. However, it is possible that your friend is very polite and does not want to hurt your feelings by not laughing. In that case, the laugh is really measuring your friend's politeness and not your expertise in telling jokes. The "laugh" measure, in this case, is not valid. It does not measure what you think it is measuring.

The concept of validity is critical in research, too. If you develop a scale to measure the conceptual variable of anxiety, but it really measures fear, the scale is not valid. Conceptual variables are abstract ideas that form the basis of research designs. What does the concept of anxiety mean to you? How would you define anxiety to another person? Only after conceptual variables are precisely defined can they be turned into measureable variables.

In this Discussion, you will turn a conceptual variable into a measureable variable by creating and administering your own scale, and by considering the scale's reliability and validity.

To prepare:

• Read Chapter 4 of the course text. Pay particular attention to the Likert scale illustrated on page 75.

• Read Chapter 5 from the course text.

• Review the assigned readings from Chapters 1-3 from the previous weeks.

• Identify conceptual variables that may be of interest to you. A few examples are anxiety, conformity, and leadership.

• Create your own 5- to 10-item Likert scale to assess a conceptual variable of interest to you.

• Administer the scale to at least three friends or family members. You may administer it in person or via e-mail.

• Prepare to upload the Likert scale you created as an attached document (in .doc or .rtf format) to your Discussion post.

With these thoughts in mind:

• The conceptual variable you selected. Note: Include the conceptual variable in the "Subject"field of your post (e.g., Job Satisfaction).

• In the main body of your post:

• Discuss your experience writing and administering the scale.

• Explain how your scale turned your conceptual variable into a measured variable (beyond creating a Likert scale).

• Explain the strengths and limitations concerning the reliability and validity of your scale.

• Upload the Likert scale you created as an attached document (either a .doc or .rtf file).

Note: Be sure to support the responses within your Discussion post, and in your colleague reply, with evidence from the assigned Learning Resources.

Respond to at least one of your colleagues' initial Discussion assignment postings in one of the following ways: (I have attached a colleague discussion post below that I need to respond to)

• Ask a probing question about the scale and provide the foundation, or a rationale, for the question.

• Support or offer a different perspective to a colleague's explanation about how he or she turned the conceptual variable to a measured variable.

• Support or offer a different perspective to a colleague's explanation of the strengths and limitations concerning the reliability and/or validity of his or her scale.

Note: You are required to complete your initial post before you will be able to view and respond to your colleague's postings. After clicking on the "Post to Discussion Question" link, select "Create Thread" to create your initial post.
