Calculate the weighted mean of the numbers 10, 20, and 30 with weights 1, 2, and 3 respectively.
Step 1: Identify the numbers and their corresponding weights. The numbers are 10, 20, and 30, and their weights are 1, 2, and 3.
Step 2: Multiply each number by its weight. Calculate 10 * 1, 20 * 2, and 30 * 3.
Step 3: Add the results of the multiplications together. This gives you the total: 10*1 + 20*2 + 30*3.
Step 4: Calculate the sum of the weights. Add the weights together: 1 + 2 + 3.
Step 5: Divide the total from Step 3 by the total from Step 4. This gives you the weighted mean.
Weighted Mean – The weighted mean is calculated by multiplying each value by its corresponding weight, summing these products, and then dividing by the total of the weights.
