Install
npx vskill@latest install cxcscmu/skilllearnbench/excel-analysisSKILL.md
Weighted Mean
Use SUMPRODUCT to calculate the weighted mean. Formula: =SUMPRODUCT(values_array, weights_array) / SUM(weights_array) Ensure the result is multiplied by 100 if the values are proportions.
Percentiles
Use the PERCENTILE.INC function. Formula: =PERCENTILE.INC(array, k) where k is 0.25 for 25th percentile and 0.75 for 75th.
Rounding
Use the ROUND function to limit decimal places. Formula: =ROUND(value, 1) If the value is a percentage in proportion format (e.g., 0.123), use =ROUND(value * 100, 1).
