What are the importance of the mean in statistics?
the mean is important in statistics because you will find out your average and can compare that mean to other things..
What is point estimation?
In statistics, point estimation is the process of providing a number or vector (which could be an infinite dimensional vector such as a function) that is stochastically 'close' in some sense to the actual value of that number or vector. For example, suppose that a population of people has a known mean height of 180 cm and an unknown standard deviation. Point estimation could be applied to a sample from this population to obtain an estimate of the standard deviation of its heights.
What does it mean to translate a vector?
Translating a vector is sliding it parallel to the axes - without changing its magnitude or direction.
Disadvantages of the mean in statistics?
the mean is affected by outliers
What does the pointing vector represent?
A vector already points, without needing an extra. I wonder if you mean "Poynting Vector" which shows the direction and magnitude of power flow in radiation.
