Psychometrics
Psychometrics refers to the theory and technique of psychological measurement. Understanding the different types of statistics utilized in assessments is essential in understanding how and why a test was developed, how a test is administered, and the results of the test itself. Without understanding these concepts, it would be very difficult to examine data and extract a meaningful interpretation, which is the whole point of conducting a psychological assessment. As you will see, there are a wide range of statistics utilized within assessments that serve a variety of purposes.
In your previous courses, you learned about many psychometrics, such as t-tests, z-scores, and type I and type II errors. In this module, you will revisit these psychometric concepts from your previous courses and apply them to psychological assessments. The foundational understanding of these concepts will allow you to understand how these statistics are utilized within the administration and results of psychological assessments. You will begin to explore what it is like to interpret data in a meaningful way and apply these psychometrics to examine the assessment utilized in your final project vignette. After this week, you should have gained a thorough understanding of the application of statistics to psychological assessments. In addition, you will submit your first milestone activity in this module.
