For example, is … Websuch as an odds ratio or risk ratio. When using a RATIO instead of a DIFFERENCE, the situation of no difference between the 2 groups will be indicated by a value of 1 instead of 0. If the ratio equals to 1, the 2 groups are equal. Hence, if the 95% CI of the ratio contains the value 1, the p-value will be greater than 0.05.

WebA standard deviation of 1 may be high or low – it depends on the data set and its mean. For a data set with a mean of 100 and a standard deviation of 1, the coefficient of variation is: CV = S/M = 1/100 = 0.01 This coefficient of variation is far less than 1, so a standard deviation of 1 is low in this case.
