Example (paired data)A study about whether eating oat bran lowered serum cholesterol levels. 14individuals were randomly assigned a diet that included either oat bran or cornflakes. After two weeks on the initial diet, serum cholesterol were measured and theparticipants were then "crossed-over" to the alternate diet. After two-weeks on thesecond diet, cholesterol levels were once again recorded.
