Measurement Scales

Conducting psychological research generally involves collecting a large amount of data. In order to summarize and draw conclusions about the data, we must first have some knowledge about the various statistical concepts. Descriptive statistics and inferential statistics are what we use to describe or summarize the data and make conclusions and predictions about a population. How variables are defined and measured is critically important in order to evaluate the validity of the research.

Instructions:

• Provide one example (your own) of each measurement scale, and provide an example (your own) of how a variable might be measured by different scales.
• Explain which of these you found most challenging to identify and why.

Your post should be at least 300 words. Respond to at least two of your classmates’ postings. Consider in your response whether you think the example provided is accurate and why. Seek out peers who shared similar examples as your own, as well as those who shared different examples from your own. Compare and contrast your rationale for your choices.
