SPSS: Independent-Samples t Test Assignment
Overview
You will be completing two independent-samples t tests in SPSS, using data that are related to specific research scenarios in the behavioral sciences, such as psychology, social work, and counseling.
Behind the scenes knowledge of how this test is conducted is fundamental to being able to understand and apply research in your related field to your practice. Additionally, SPSS skills are professionally valuable, as it is one of the most commonly used statistical software packages in behavioral science settings, both academic and professional.
Instructions
