What formula do I need to enter in A7 below if what I need is the weighted average of the filtered list where column B values (amount) is my weight. This is a simplified list where I would use filtering and subtotal commands in row 7, but since there is no function number for weighted average in the subtotal command (only 1 for simple average ...
Hello Excel team, I have a table of stock purchase data and I would like to calculate a weighted average by date. I would like the most recent dates to carry more weight than the older trades/data. So as new transactions get entered into the table the weights should adjust and push down so...
Row 764 shows the formulas to calculate the weighted average in Cell C763. My goal is to find a way to get the actual result through a formula (e.g. =wmav(A766), knowing that the 'period' may be any number and that new data are continuously added to column B. Cheers
Option Explicit Function WeightedAvg( _ Values, _ Weights) As Double Dim ValuesArray, _ WeightsArray If TypeName(Values) = "Range" Then ValuesArray = Range_to_1D_Array(Values) Else If TypeName(Values) Like "*()" Then If ArrayDimensions(Values) > 1 Then ValuesArray = Excel.Application.Transpose(Values) Else ValuesArray = Values End If End If End ...
The formulas that I provided do correctly calculate the weighted average of __something__. But it might not be the correct weighted average for your purposes. GIGO! For example, many people miscalculate average speed by weighting by distance, to wit: SUMPRODUCT(speeds, distances) / SUM(distances).
For the Average calculation I am using formula 1 below that works for both criteria above but I need this formula to now calculate a weighted score per cell. 1. =ROUND(IF(NOT(ISTEXT(E6:H6)),AVERAGE(E6:H6)),5) I tried calculating the weighted score first but the formula returns #VALUE! if N/A or N/A is an input in the cell. 2.
In this example, the scores are higher in the two tests that matter - C and D have the higher weightings. Hence the weighted average is higher than the simple average. But if you set the weights identically, the weighed average will equal the simple average, 58%. In your example, you could in theory weight either by total units, or by monthly ...
Hi everyone I just wondered if it's possible to use a sumproduct formula to calculate a weighted average for data in non-adjacent cells.
Hi Everyone, Was hoping someone might have an answer to this one as it seems to be one of the great misteries of the internet. So I need a real accurate calculation for the weighted average life of a mortgage where the amounts paid each month are know but variable. assume the period is...
Joe Bloggs has sat all 5 exams, so his final weighted average is simple to calculate ... Note: each bracket involves the corresponding exam weighting being divided by 100, because Joe sat all 5 exams and the combined weighting of all 5 exams came to 100
