How would you calculate a weighted mean in R?
- Use the weighted.mean() function
- Use the mean() function with the weights specified as an argument
- Use the sum() function to calculate the sum of values multiplied by weights, then divide by the sum of weights
- Use the wmean() function
To calculate a weighted mean in R, you would use the weighted.mean() function. The weighted.mean() function takes two arguments: the values to be weighted and the corresponding weights. It computes the weighted average based on the provided weights.
