Calculate means, standard deviations, coefficient of variation, and standard error of the means (SE) for each sample data set (1-4) separately. If you add 20 to each value what happens to the means, standard deviations, coefficient of variation, and SE? Explain with words as well as show one example (pick one sample data set) to support your explanation numerically. Using the means you just calculated, consider these means from each sample set as a new sample set v Bold n=4 and calculate their mean. Do the same approach and find standard deviations of this new small sample set. Explain with your words why the variation among the four means is smaller than the mean(average) of the four standard deviations.
