Statistics (OpenStax)

Statistics (OpenStax)

Statistics introduces learners to concepts in statistics and is geared toward students majoring in fields other than math or engineering. This course assumes some knowledge of intermediate algebra and focuses on application over theory. It also focuses on the interpretation of statistical results, especially in real world settings.

Statistics includes a pre-assessment and assessment, interactive exercises, flashcards, and games that appeal to a variety of learning styles. Case studies give students opportunities to use critical thinking skills and apply their knowledge to real-world ethical scenarios. This learning resource also reviews the major principles of mathematical statistics.

 

MindEdge has enhanced OpenStax courses with interactive games, video commentary, adaptive learning segments, additional practice questions, and a robust question database.
