... the real data are assumed to be a sample. The population must be clearly defined. In this example, it could be all hypothetical sets of 10 tosses of a fair coin using a precise method under standard conditions. Clearly, 7 heads from 10 tosses is perfectly possible even with a fair coin, but the more ...

Using SAS® to Create an Effect Size Resampling Distribution for a Statistical Test
... That is, the sample mean differs from the hypothesized mean by more than ½ an observed standard deviation for a medium effect size. For assessing clinical/operational significance the effect size is more meaningful than the p-value which is strongly influenced by the sample size. Note that in the on ...

... If a distribution is skewed to the right, its median is often greater than its mean. If the right and left sides of a histogram are mirror images of each other, the distribution is symmetric. A distribution spread far to the left is said to be skewed to the left. ...

... a. What is the value of the test statistic? (103-100)/(18/sqrt(18)) = 3/2 = 1.5 b. What is the rejection region at alpha of 0.05? >1.96 or <-1.96 c. What will be your decision at alpha of 0.05? Fail to reject H0 d. What is the p-value for this study? 2*P(z>1.5) = 2*(1-0.93319) = 2*0.06681=0.13362 e. ...
