Understanding Measurement

Discussion Topic: Understanding Measurement

The Thread  – Respond to Part 1 and 2 in one Thread.  The Thread must be 400 to 500 words (see Notes).

Part 1 – What are the four levels of measurement? must be 250 to 300 words

• Describe the characteristics of each level of measurement.
• Provide an example of each level of measurement.

Part 2 – What is content validity, and how is it specified?  Provide an example. (150 words±)

Post your initial Thread and attach a Word document of your work (see Notes).

The Replies – Each reply (x2) must be 100 to 200 words (see Notes).

You are required to write substantive replies to a minimum of two of your classmate’s initial thread.  In contrast to superficial replies, substantive replies add value to the discussion, enhance learning, and contain references to any new concepts or ideas presented.

The following suggestions will aid you in successfully composing substantive responses:

• Compare/contrast the findings of others with your research or experience.
• Compare how the findings of others enhance the concepts learned in the required readings.
• Share additional knowledge regarding the topic that relates to the thread.

Assignment Notes:

• Examples of reliable publications may include Forbes, The Wall Street Journal, Business Week, Barron’s, Retail Business News, etc.  Online sources are acceptable if correctly cited, and a link is included.  APA in-text citations and references are required.  Wikipedia is not considered a reliable publication.  You may not use the examples already provided in the study materials or your classmate’s threads.
• Failing to meet word count requirements will be penalized.  There is no advantage to exceeding the word count suggestions.  Titles, Bible references, quotes, scripture, title page, abstract, references, citations, and reference pages cannot fulfill word count requirements.
