Standard deviation Sentence Examples

Thus a series of arrays of beech leaves, gathered, subject to the precautions indicated, from each of loo beech trees in Buckinghamshire by Professor Pearson, gave 16.1 as the mean number of veins per leaf, the standard deviation of the veins in the series being 1.735.

The mean and standard deviation of all first leaves or of all second leaves will clearly be the same as those already determined for the series of leaves; since every leaf in the series is used once as a first member and once as a second member of a pair.

We see therefore that while leaves, gathered in equal numbers from each of loo trees, are distributed about their mean with a standard deviation of 1.735 veins, the leaves gathered from a single tree are distributed about their mean with a standard deviation of 1.426 veins, the ratio between variability of the race and variability of the individual tree being 1 - (0-5699)1=0.822.

We may therefore conclude that for large classes of characters, both animal and vegetable, the variability of an individual, as measured by the standard deviation of its undifferentiated but repeated organs, is a constant fraction of the variability of its race, as measured by the standard deviation of the corresponding series of organs produced by all the individuals of its race.

E is the normalized structure amplitude, SIGE is its standard deviation.

The simplest approach to this is to calculate the standard deviation.

The repeatability standard deviation is smaller at lower chloride levels.

If you take the natural logarithm of this distribution, you'll get a normal distribution with mean mu and standard deviation sigma.

Their equation used the standard deviation of the stock price and the risk-free interest rate to provide a value.

The column to the right of each of these gives the standard deviation for the set of 100 individual runs.

The effect size statistic is equal to the mean change in instrument scores divided by the baseline standard deviation [36] .

Notwithstanding this differentiation, the mean character of a series of repeated organs is often constant through a considerable region of the body or a considerable period of time; and the standard deviation of an "array" of repeated parts, chosen from such an area, or within such limits of time, may be taken as a.

The coefficient of correlation is 0.5699, which indicates that the standard deviation of an array is equal to that of the leaves in general multiplied by 1 / I - (0.5699) 1; and performing this multiplication, we find 1.426 as the standard deviation of an array.

From this result it follows (see Probability) that the standard deviation of the array, which we have taken as a measure of individual variability, is equal to the standard deviation of the race multiplied by V I - (2) z or by * These results cannot be accepted as final, but they are based on so many investigations of animals and plants, of such widely different kinds, that they may confidently be expected to hold for large classes of organic characters.

Firstly the standard deviation of the distribution of income is required.

The spread is usually calculated by taking the standard deviation of the scores.

The abscissa is the standard deviation of the relative error on coordinates of image point or calibration parameters.

With the same probability, Gaussian noise is added to the tolerance value (mean 0, standard deviation 0.01).

The effect size statistic is equal to the mean change in instrument scores divided by the baseline standard deviation [36 ].

Also tabulated with each value are the number of points used and the standard deviation.

The test has a mean, or average, standard score of 100 and a standard deviation of 15 for composite scores (subtests have a mean of 10 and a standard deviation of 3).

The standard deviation indicates how far above or below the norm the subject's score is.

This child's score would be one standard deviation above that norm.
