Worked Solution & Example Answer:The vitamin C content of a carton of orange juice was determined by four students - Scottish Highers Chemistry - Question 15 - 2023
Step 1
The most reproducible results were obtained by
Answer
To determine the most reproducible results, we analyze the data for each student and look for the least variation among their results:
- Student A: Results are 30.0, 29.0, 28.0. The variation is high with a range of 2.0.
- Student B: Results are 26.4, 26.6, 26.8. The variation is low with a range of 0.4.
- Student C: Results are 26.9, 27.0, 26.9. The variation is very low with a range of 0.1.
- Student D: Results are 26.9, 26.5, 26.9. The variation is low with a range of 0.4.
Given the analysis, Student C has the smallest range, indicating the most reproducible results. Thus, the answer is:
C Student C.
