... The results do not support the claim that magnets are effective in reducing back pain. Even though the mean pain reduction with magnets (0.49) was greater than with the sham treatment (0.44), the standard deviations were very high (0.96 and 1.4), making it difficult to statistically find any meaning ...

Notes from Lecture 12
... Suppose we have a sample statistic, and we know the sample size (n), and we have some estimate of the variance in the population (σ). Our hypothesis provides a guess at the population parameter we care about. Using the normal distribution, we can then calculate the probability that we would have obt ...

... A point estimate is a single value. The problem with point estimates is that the accuracy of the estimate cannot be determined, so the interval estimate is preferred. © Copyright McGraw-Hill 2004 ...
