Discussion 2: Optimizing Sampling And Data Collection
The data that you collect from your norm group is called normative data. It allows you to see what the results of your test instrument should be, so that you have a standardized score against which to compare others. In other words, it allows you to equate scores across different tests of the same construct and lets you compare individuals to each other. Now that you have considered sampling the population of interest for your proposed test instrument, you explore how you might optimally define your sample and collect your data if you had unlimited resources. Though it may not always be possible for practical reasons to do this in real life, this exercise nevertheless provides you with a valuable thought experiment.
As you complete this experiment, keep in mind that even with optimal sample definition and data collection, test norms are not absolute. They can change with time or with a different norm group.
With these thoughts in mind:
Post by Day 4 a description of the information you anticipate collecting through your proposed Final Project instrument. Then explain how you would optimally define your sample and collect your data if you had unlimited resources. Finally, explain advantages and disadvantages of your chosen data collection method. Support your response using the Learning Resources and the current literature.
Be sure to support your postings and responses with specific references to the Learning Resources.
