How do you get weighted mean?
A weighted mean is when some values contribute more than others. In order to calculate weighted mean multiply each weight by its value, add those and then divide by the sum of the weights.
In Mathematical terms what does the term weighted average mean?
In mathematical terms a weighted average is one which takes account of the popularity or frequency that particular numbers appear in the collection that is being averaged. It is considered to give a more realistic average.
Is there any difference between expected value and arithmetic mean?
There is. Arithmetic mean is simple average of numbers not weighted by anything. However in EV, the numbers are weighted by their probability
What math or algebra terms begin with the letter W?

What does weighted average mean?
The weighted arithmetic mean is used, if one wants to combine average values from samples of the same population with different sample sizes: : The weights wi represent the bounds of the partial sample. In other applications they represent a measure for the reliability of the influence upon the mean by respective values. rhinostar

Is it the arithmetic mean or weighted mean that is more accurate Why?
The arithmetic mean and the weighted mean are used in different situations. The arithmetic mean is used in frequencies as a general average. The weighted mean is used when different factors contribute to some kind of total for example with weighted index numbers. It is not a matter of accuracy it involves using the right mean in the right situation. Almost always (if not always) a question will specify which mean to use.
