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.

if anyone is in grade 7 trying to find this answer, sorry I am not too sure know, just wanted to be first
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 is the weighed mean of 10 11 12 13 14 10 10 10 12 and 14?
In order to find the weighted mean of this set of the data, we need to know the weight for each data in the set, and this information is not given in your question.Definition: When each number ai is to have weight wi, the weighted mean is equal to(w1a1+w2a2 + ... + wnan)/(w1 + w2 + ... + wn).

Geometric mean
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.
What is the definition of 'weighted mean'?
"Weighted mean" is the average calculated by taking into account not only the frequencies of the variables but also some other factors such as their variance.
