Five vendors are being considered for a service. The evaluation committee evaluated each vendor on six aspects – Cost, Customer Service, Features, Quality, Reach, and Reliability. Each of these evaluations are on a scale of 0 (worst) to 100 (perfect). The evaluation scores on these aspects are shown in the radar chart. For example, Vendor 1 obtains a score of 52 on Reliability, Vendor 2 obtains a score of 45 on Features and Vendor 3 obtains a score of 90 on Cost.
Q.1 On which aspect is the median score of the five vendors the least?
- Reliability
- Quality
- Customer Service
- Cost
Explanation
Answer: 3
The scores of venders given in graph can be tabulated as below:
| Reliability | Reach | Quality | Features | Customer S | Cost | Total | |
| Vendor 1 | 52 | 80 | 70 | 40 | 55 | 80 | 377 |
| Vendor 2 | 40 | 60 | 70 | 45 | 40 | 80 | 335 |
| Vendor 3 | 75 | 60 | 60 | 55 | 50 | 90 | 390 |
| Vendor 4 | 25 | 45 | 40 | 90 | 70 | 70 | 340 |
| Vendor 5 | 60 | 70 | 50 | 75 | 28 | 60 | 343 |
- Median of reliability = 52; median of quality = 60; median of customer s = 50 median of cost = 80 Clearly the median of customer s is minimum.
- The vender which has highest total will have highest average. vendor 3 has highest total thus highest average.
- Vendor 1 and 5 have 3 top two scores each.
- Clearly vendor 3
Q.2 A vendor’s final score is the average of their scores on all six aspects. Which vendor has the highest final score?
- Vendor 3
- Vendor 2
- Vendor 4
- Vendor 1
Explanation
Answer: 1
The scores of venders given in graph can be tabulated as below:

| Vendor 4 | 25 | 45 | 40 | 90 | 70 | 70 | 340 |
| Vendor 5 | 60 | 70 | 50 | 75 | 28 | 60 | 343 |
- Median of reliability = 52; median of quality = 60; median of customer s = 50 median of cost = 80 Clearly the median of customer s is minimum.
- The vender which has highest total will have highest average. vendor 3 has highest total thus highest average.
- Vendor 1 and 5 have 3 top two scores each.
- Clearly vendor 3
Q.3 List of all the vendors who are among the top two scorers on the maximum number of aspects is:
- Vendor 1 and Vendor 2
- Vendor 1 and Vendor 5
- Vendor 2 and Vendor 5
- Vendor 2, Vendor 3 and Vendor 4
Explanation
Answer: 2
The scores of venders given in graph can be tabulated as below:

| Vendor 5 | 60 | 70 | 50 | 75 | 28 | 60 | 343 |
- Median of reliability = 52; median of quality = 60; median of customer s = 50 median of cost = 80 Clearly the median of customer s is minimum.
- The vender which has highest total will have highest average. vendor 3 has highest total thus highest average.
- Vendor 1 and 5 have 3 top two scores each.
- Clearly vendor 3
Q.4 List of all the vendors who are among the top three vendors on all six aspects is:
- Vendor 1 and Vendor 3
- Vendor 3
- Vendor 1
- None of the Vendors
Explanation
Answer: 2
Solution:
The scores of venders given in graph can be tabulated as below:
| Reliability | Reach | Quality | Features | Customer S | Cost | Total | |
| Vendor 1 | 52 | 80 | 70 | 40 | 55 | 80 | 377 |
| Vendor 2 | 40 | 60 | 70 | 45 | 40 | 80 | 335 |
| Vendor 3 | 75 | 60 | 60 | 55 | 50 | 90 | 390 |
| Vendor 4 | 25 | 45 | 40 | 90 | 70 | 70 | 340 |
| Vendor 5 | 60 | 70 | 50 | 75 | 28 | 60 | 343 |
- Median of reliability = 52; median of quality = 60; median of customer s = 50 median of cost = 80 Clearly the median of customer s is minimum.
- The vender which has highest total will have highest average. vendor 3 has highest total thus highest average.
- Vendor 1 and 5 have 3 top two scores each.
