PPT-Chapter 20: Testing Hypotheses About Proportions

AP Statistics Unit 5 Hypotheses Hypotheses are working models that we adopt temporarily Our starting hypothesis is called the null hypothesis The null hypothesis that we denote by H 0.

This valuable resource integrates motor learningtheory with the physiological underpinnings of voice production to make therehabilitation process more accessible and cohesive. Dialogues betweenthe patient and the clinician interwoven with the voice clinician\'s internalmonologue provide insight into the active clinical reasoning process. A review of the etiologies and physiological changes associated with frequently diagnosed laryngeal pathologies provides a useful reference.FEATURES- Video clips featuring in-session demonstration and modification of procedures- Step-by-step description of voice exercise and rationales for their implementation- Special chapter devoted to the singer, transgender client, and patient who suffers from spasmodic dysphonia- Framework for group voice therapy- Counseling to address adherence, readiness for change, and generalization- Comprehensive discussion of risk factors for professional and customary voice users- Chapter Objectives, Review of Laryngeal Pathologies, Voice Evaluation ProtocolTEACHING TOOLS- Instructor\'s Manual, featuring frameworks for class discussions Case Studies and Key Chapter Terms and ConceptsSTUDENT RESOURCESNavigate Companion Website*, including: - Interactive Learning Activities- Interactive Glossary- Videos*Each new copy of the text includes an access code to the Navigate Companion Website Voice Rehabilitation: Testing Hypotheses and Reframing Therapy offersa patient-centered, hypothesis-driven framework for clinicians beginningto practice voice rehabilitation as well as practicing clinicians who continueto develop their skills.
