In this course, different terms are used to designate tasks:
- ADAPTivities: Adaptive exercises designed to help you retain important content and information. There are generally two types identified by name:
- 1. Learn By Doing activities: Learn By Doing activities give you the chance to practice the concept that you are learning, with hints and feedback to guide you if you struggle.
- 2. Did I Get This? activities: Did I Get This? activities are your chance to do a quick "self-check" and assess your own understanding of the material before doing a graded activity.
- StatTutor: StatTutor is an interactive learning tool that provides you with a data analysis problem, supports you as you attempt to solve it, and gives you hints and feedback along the way.
- Checkpoint: A graded online assessment or “Quiz” covering a full module
- Final Exam: A comprehensive proctored final examination
StraighterLine provides a percentage score and letter grade for each course. A passing percentage is 70% or higher.
