Weighted Mean Calculation:
To find the weighted mean of the marks for the subject, we need to multiply the marks obtained in each examination by their respective weights, and then calculate the average of these weighted marks.
Given:
Theory marks = 35
Practical marks = 15
Oral marks = 5
Weights:
Theory weight = 4
Practical weight = 2
Oral weight = 1
Step 1: Multiply marks by their respective weights
Theory weighted marks = Theory marks * Theory weight = 35 * 4 = 140
Practical weighted marks = Practical marks * Practical weight = 15 * 2 = 30
Oral weighted marks = Oral marks * Oral weight = 5 * 1 = 5
Step 2: Sum up the weighted marks
Total weighted marks = Theory weighted marks + Practical weighted marks + Oral weighted marks
Total weighted marks = 140 + 30 + 5 = 175
Step 3: Find the total weight
Total weight = Theory weight + Practical weight + Oral weight
Total weight = 4 + 2 + 1 = 7
Step 4: Calculate the weighted mean
Weighted mean = Total weighted marks / Total weight
Weighted mean = 175 / 7 = 25
Explanation:
The weighted mean of marks for this subject is 25. The weighted mean takes into consideration the weights assigned to each examination while calculating the average. In this case, the theory examination has the highest weight of 4, followed by the practical examination with a weight of 2, and the oral examination with a weight of 1.
To calculate the weighted mean, we multiply the marks obtained in each examination by their respective weights. Then, we sum up the weighted marks and divide it by the total weight. This gives us the weighted mean.
In this example, the student scored 35 marks in the theory paper, which is multiplied by the weight of 4 to get 140. The student scored 15 marks in the practical examination, which is multiplied by the weight of 2 to get 30. The student scored 5 marks in the oral examination, which is multiplied by the weight of 1 to get 5.
The total weighted marks is the sum of these weighted marks, which is 175. The total weight is the sum of the weights assigned to each examination, which is 7.
Finally, the weighted mean is calculated by dividing the total weighted marks by the total weight. In this case, the weighted mean is 25.
