The more precise a result, the smaller will be the standard deviation of the data the result is based upon.
No, average deviation cannot be negative. Deviation is a representation of differences between numbers. A difference is always an absolute value, so the number cannot be negative (even though subtracting the deviation from an average may result in a a negative result).
Yes. Consider the definition of the standard deviation. It is the square root of the variance from the mean. As a result, it can be said that the standard deviation is dependent on the mean.
Assuming var is variance, simply square the standard deviation and the result is the variance.
absolute deviation is a difference between say two numbers. The result has the same units as the two numbers have. Relative deviation is a ratio and so it is a pure number without any units.
out of operational necessity
A single observation, such as 50486055535157526145 cannot have a standard deviation cube test compressive result.
16.5 is 1 standard deviation from the mean. If you add the mean of 14 to the 1 standard deviation of 2.5, the result is 16.5.
Compass error refers to a magnetic compasses natural tendencies to produce erroneous readings in certain circumstances. Sometimes this may be due to environmental effects such as proximity to a strong magnetic field. Compass error is also frequently the result of shortcomings or anomalies in the way compasses work. Compass error due to environmental effects usually refers to an airplanes compass being drawn toward the magnetic fields generated by the aircrafts engines. This is called magnetic deviation. Additionally in some regions with high concentrations of iron in the soil, compasses may give all sorts of erroneous information. Magnetic compass "variation" deals with the difference between the magnetic north pole (which magnetic compasses point to) and the true north pole (the actual geographical north pole.) While this difference may seem minor, magnetic variation can mean a difference of up to 4 or 5 degrees in some places. In aviation, compasses may also give erroneous readings when turning or performing other maneuvers. This is due to the curvature of the earth combined with the fact that the compass needle wishes to point at the magnetic north pole. Since the earth is round, and the compass points to the magnetic north pole, the compass needle will in most cases be drawn to a point below the horizon from the users standpoint. This will cause the magnetic compass to precede when turning to a northern heading, and to lag when turning to a southern heading.
by using the compass you can accurately get the result
In a data sample, the purpose of quartile deviation is a way to measure data dispersion instead of using the range. The quartile deviation is found by subtracting the lower quartile from the upper quartile, and dividing this result by two.
Deviation can destroy cell, causing death/mutation.
