Week 2 – Assignment: Create a Table to Group Items Representing a Common Concept
Hide Folder Information
Instructions
Below are statements coming from different psychological scales constructed by different authors; what the scales are measuring nor the number of scales that are represented by these items are identified. Since the psychological variables measured by the items are fairly easily identifiable, create a table in which you will group those items that represent a common concept. Then, invent a construct or variable name for these items. This is an exercise that tests your intuitive abilities to spot the supposedly hidden constructs represented by these items. Consider this assignment as an “armchair” factor analysis.
