In contrast to loose connective tissue types where protein fibers are small and less abundant, dense connective tissues possess large, robust fibers that impart to these tissues considerable strength. Fibers are so numerous the extracellular matrix contains few if any open spaces where ground substance is visible.
Standard deviation is a mathematical measurement of average variance and features prominently in statistics, economics, accounting and finance. For a given data set, the standard deviation measures how spread out numbers are from an average value. Standard deviation can be calculated by taking the square root of the variance, which itself is the average of the squared differences of the mean. When it comes to mutual fund or hedge fund investing, analysts look to standard deviation more than any other risk measurement.
Standard deviation is a mathematical tool to help us assess how far the values are spread above and below the mean. A high standard deviation shows that the data is widely spread (less reliable) and a low standard deviation shows that the data are clustered closely around the mean (more reliable).ypothesis: The berries from the tree with yellow & green leaves will be smaller than the berries from a tree with all-green leaves. The difference in mean berry mass between the 2 tree types is 28 mg. The standard deviations are 73 mg and 80 mg.
