Areal rainfall refers to the average amount of rain that falls over a specific area within a given period of time, typically measured in millimeters or inches. It is used to assess the overall water supply and distribution in a particular region and can vary significantly across different geographical areas.
Rainfall is the amount of precipitation, in the form of water droplets, that falls to the Earth's surface. Humidity is the amount of water vapor present in the air. Wind is the movement of air caused by pressure differences in the atmosphere.
The average annual rainfall in Washington, D.C. is around 40 inches.
As the angle of incidence is increased, angle of deviation 'd' decreases and reaches minimum value. If the angle of incidence is further increased, the angle of deviation is increased. Let dm be the angle of minimum deviation. The refracted ray in the prism in that case will be parallel to the base.
The mean average deviation is the same as the mean deviation (or the average deviation) and they are, by definition, 0.
You don't need to. The mean deviation is, by definition, zero.
Simple! The average deviation for any data set is zero - by definition.
Standard deviation is how much a group deviates from the whole. In order to calculate standard deviation, you must know the mean.
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.
No. Mean absolute deviation is usually greater than 0. It is 0 only if all the values are exactly the same - in which case there is no point in calculating a deviation! The average deviation is always (by definition) = 0
No. Standard deviation is the square root of a non-negative number (the variance) and as such has to be at least zero. Please see the related links for a definition of standard deviation and some examples.
The standard deviation of a single observation is not defined. With a single observation, the mean of the observation(s) would be the same as the value of the observation itself. By definition, therefore, the deviation (difference between observation and mean) would always be zero. Rather a pointless exercise!

it is the angle between the direction of the incident ray and the refracted ray.
