MATH 225N Week 5 Assignment: Understanding Normal Distribution

MATH 225N Week 5 DiscussionMany variables in medicine follow a normal distribution where there are approximately an equal number of values below the mean as above the mean. Describe two variables that you work with that would probably follow a normal distribution. Also note which of the two variables would be likely to have a larger standard deviation and why. Statistical data is indispensable to physicians, and the knowledge of statistics is essential not only for research but also for underst...
