Lab Report Grade Calculator

Calculate your lab report grade easily with this free Lab Report Grade Calculator. Enter scores for sections like analysis, procedure, and presentation.

Lab Report Grade Calculator

Calculate your lab report grade based on scores from various sections like hypothesis, methodology, results, and analysis.

Understanding the Concept

Lab reports are graded using multiple sections, each with a specific weight. The formula for the final grade is:

Final Lab Report Grade = \((\text{Section 1 Score} × \text{Weight 1}) + (\text{Section 2 Score} × \text{Weight 2}) + …\)

Example Calculation

Suppose a lab report is graded as follows:

Section Score Weight (%)
Introduction & Hypothesis 18/20 20
Methodology & Procedure 25/30 30
Results & Data Analysis 35/40 40
Conclusion & Discussion 8/10 10

Final Grade = (18/20 × 20) + (25/30 × 30) + (35/40 × 40) + (8/10 × 10)
= (0.9×20) + (0.833×30) + (0.875×40) + (0.8×10)
= 18 + 25 + 35 + 8 = 86% → B+ Grade

How to Use the Lab Report Grade Calculator

  • Input scores for each section of the lab report.
  • Enter the weight assigned to each section.
