What is the difference between average and weighted average?
The average is the sum of all individual observations divided by the number of observations. In contrast, the weighted average is observation multiplied by the weight and added to find a solution. An average is a mathematical equation, whereas the weighted average is applied in the daily activities of finance.

What is mode formula?
In statistics, the mode formula is defined as the formula to calculate the mode of a given set of data. Mode refers to the value that is repeatedly occurring in a given set and mode is different for grouped and ungrouped data sets. Mode = L+h(fm−f1)(fm−f1)−(fm−f2) L + h ( f m − f 1 ) ( f m − f 1 ) − ( f m − f 2 )
How is Eva WACC calculated?
EVA Formula
WACC = Weighted Average Cost of Capital. Capital invested = Equity + long-term debt at the beginning of the period. (WACC* capital invested) is also known as a finance charge.
