Better measures of the distribution of scores are the variance and standard deviation. The variance (2) is the sum of the squares of the deviations of the individual test scores (xi) from the mean () divided by the number of scores (n). The standard deviation () is the square root of the variance.
Reducing triglyceride levels is one of the main mechanisms by which fish oil omega-3 fatty acids improve cardiovascular health. With regards to cholesterol, fish oil omega-3 fatty acids can increase the level of âgoodâ cholesterol while lowering âbadâ cholesterol. However, this relationship is not straightforward. In fact, fish oil can raise LDL cholesterol in people with high blood triglyceride levels.
The higher potency of krill oil allows it to decrease triglyceride levels in a shorter period of time compared to fish oil. Overall, after six weeks of supplementation, cholesterol levels in the krill oil group declined by 33 percent, compared to 21 percent in the fish oil group. Further, liver triglycerides were reduced by TWICE as much in the krill oil group compared to the fish oil group, by 20 percent and 10 percent, respectively.
