answer:
option b is correct answer, ( the arithmetic mean can be calculated from any variables. )
the explanation is,
- One strategy is to figure the number juggling mean.
- To do this, include every one of the qualities and partition the whole by the quantity of qualities.
- these are as the for instance, if there are a lot of "n" numbers, include the numbers together for instance: a + b + c + d, etc.

The mean, median, and mode are all measures of central tendency.The mean is usually the preferred measure of central tendency, but there are specific situations in which it is impossible to compute a mean or in which the mean is not particularly representative of the distribution.Which of the following statements about the mean are true? Check all that apply.There can be more than one.It is commonly referred to as the arithmetic average.It always corresponds to an actual score in the data.It...

Which of the following statement is TRUE? A: In an efficient market, the only way to earn higher returns is to invest in riskier securities. B The efficient market hypothesis means that trades can be executed quickly, easily, and inexpensively. C In a semi-strong efficient market, traders with non-public information would have no advantage over those who had only public information. D Even if weak form market efficiency is true, it does not mean that studying charts of past prices...
