## Evaluate the quality of a quantitative measurement scale Instructions

Measurement Paper Description

The purpose of this paper is some practical application of the ideas in the first part of the course to some measurement issue.

Goals and Activities

The goals of this paper are to

evaluate the quality of a quantitative measurement scale, evaluate the quality of a qualitative measurement tool, and

design two new scales.

Start by picking two measurement tools: a quantitative scale and a qualitative tool. For both, pick things that are likely able to be used to evaluate outcomes.

By now the idea of a quantitative scale will be clear, probably. The idea of a qualitative tool might not be as distinct. What is meant here is a measurement strategy that generates text (like short answers) of some type. These may be responses to a questionnaire, observations by an evaluator, unobtrusive documents, or something similar that you’ve learned about in this class.

Then use what you’ve learned so far in the class to critique the quality of each of these. Some applicable ideas include reliability, validity, and how to evaluate scale and interview questions.

Next, create two new quantitative scales.

One quantitative scale should measure the same variable as the quantitative scale you found. This scale should have at least four questions, and you need to provide the scaling for each question, that is, how the question is scored. You also need to provide an interpretation of the overall score on the scale.

The other quantitative scale should measure the same thing or things as the qualitative tool you found, using the same guidelines as for the first quantitative scale.

In your paper, include all of these, and provide an explanation and critique of each of the tools, including your own.
