The weighted rating is 442.86 points if John's approval rating is an average based upon four categories.
What is average?
It is defined as the single number that represents the mean value for the given set of data or the closed value for each entry given in the set of data.
It is given that:
John's approval rating is an average based upon four categories.
The four categories are:
- Category 1: 450 points, weight factor 1
- Category 2: 475 points, weight factor 2
- Category 3: 500 points, weight factor 1
- Category 4: 400 points, weight factor 3
To find the overall weighted rating:
Use the weighted average formula:
Weighted rating = [(450x1) + (475x2) + (500x1) + (400x3)] ÷ (1 + 2 + 1 + 3)
Weighted rating = (450 + 950 + 500 + 1200)/7
Weighted rating = 3100/7
Weighted rating = 442.86 points
Thus, the weighted rating is 442.86 points if John's approval rating is an average based upon four categories.
