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.
The standard normal distribution is a normal distribution with a mean of zero and standard deviation of 1.The standard normal distribution is centered at zero and the degree to which a given measurement deviates from the mean is given by the standard deviation.n this case, because the mean is zero and the standard deviation is 1, the Z value is the number of standard deviation units away from the mean, and the area is the probability of observing a value less than that particular Z value. Note also that the table shows probabilities to two decimal places of Z.
