Presentation on a Scale Construction
Week 7 Assignment: Develop a PowerPoint Presentation on a Scale Construction
For this task, imagine that you were asked to give a scale construction proposal to a group of hypothetical PhD students. The PowerPoint presentation should include the definition of the construct that you intend to make a scale on, the existing tools measuring it, and other related studies. Also include your justification and rationale for your construction. More importantly, discuss how you will construct the items and the item response scales, how you will analyze the items’ reliabilities, and establish the scale’s validity.
Incorporate appropriate animations, transitions, and graphics as well as speaker notes for each slide. The speaker notes may be comprised of brief paragraphs or bulleted lists.
Support your presentation with at least five scholarly resources. In addition to these specified resources, other appropriate scholarly resources may be included.
Length: 12 slides (with a separate reference slide)
Notes Length: 200-350 words for each slide
Be sure to include citations for quotations and paraphrases with references in APA format and style where appropriate. Save the file as PPT with the correct course code information.
1.0 Critique the meaning and implications of measuring psychological constructs.
2.0 Analyze the literature on a particular construct and the current tools that have been designed to measure it.
3.0 Select methods used in the creation of items that measure psychological constructs.
4.0 Appraise different approaches to establishing item and instrument reliability.
5.0 Evaluate the different approaches to instrument validation.
6.0 Discriminate methods of establishing criterion or predictive validity.
This week, you will prepare an outline for the Signature Assignment that is due on Week 8. You will create the bullet-point outline for this proposal and it should include the construct of interest the topics that will serve as the titles and subtitles of your Signature Assignment. However, provide a very brief description of what the content under each section will be like. For example, under Introduction, you can write “Here I will provide a conceptual definition of the construct;” or, under Method, you can write “I will discuss that the item-total reliability will be performed in this section.”
Be sure to review this week’s resources carefully. You are expected to apply the information from these resources when you prepare your assignments.
