Neha Gautam Section R3 Lab 7 Outline Peripheral Nervous System and Statistical Confidence I. Review of Sensory Receptors of PNS A. Special senses [info about external environment] 1. taste (gustation) 2. smell (olfaction) 3. sight (vision) 4. hearing (audition) B. Somatic senses [conditions within the body] 1. touch 2. temperature 3. pain 4. body position (proprioception) 5. variety of internal chemoreceptors (aside from taste and smell) II. Additional Tools for Data Analysis A. Determining difference between two groups 1. Confidence Interval : range of values within which you are confident the actual means lie (affected by # of samples) a. Standard Deviation (StDev): describes the variability in data 2. Confidence function: value describing range within which mean is to be found if experiment was to be replicated a. Alpha is Significance Level , probability that real mean lies outside confidence interval III. In-Laboratory Exercises
