# Data Interpretation – Five vendors are being considered for a service

## Five vendors are being considered for a service – Video Solution

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?

1. Reliability
2. Quality
3. Customer Service
4. Cost

Q.2 A vendor’s final score is the average of their scores on all six aspects. Which vendor has the highest final score?

1. Vendor 3
2. Vendor 2
3. Vendor 4
4. Vendor 1

Q.3 List of all the vendors who are among the top two scorers on the maximum number of aspects is:

1. Vendor 1 and Vendor 2
2. Vendor 1 and Vendor 5
3. Vendor 2 and Vendor 5
4. Vendor 2, Vendor 3 and Vendor 4

Q.4 List of all the vendors who are among the top three vendors on all six aspects is:

1. Vendor 1 and Vendor 3
2. Vendor 3
3. Vendor 1
4. None of the Vendors

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

1. 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.
2. The vender which has highest total will have highest average. vendor 3 has highest total thus highest average.
3. Vendor 1 and 5 have 3 top two scores each.
4. Clearly vendor 3
