360 Degree Assessment Report Calculation Rules
Display Rules for Total and Average Scores
1. Total Scores
When dimensions are set, the total score is the sum of the individual scores for each dimension (Efficient Execution, Team Collaboration, Responsibility Awareness).
Example Calculation: The total score is the sum of the scores for the three dimensions: 5.63 ..+ 2.63.. + 2.5.. = 10.75..
(Note: 5.63.. represents the exact value without rounding, and the same applies to the other values.)
When dimensions are not set, the total score is the sum of the scores for each question.
Example Calculation: 2.88.. + 2.75.. + 2.63.. + 2.5.. = 10.75..
(Note: The numbers represent exact values without rounding.)
2. Average Score
When dimensions are set, the average score is the mean of the scores for each dimension (Efficient Execution, Team Collaboration, Responsibility Awareness). Users can select this based on their needs.
Example Calculation: The average score is the sum of the scores for the three dimensions divided by three: (2.81 + 2.63 + 2.5) / 3 = 2.65
(Note: The numbers represent exact values without rounding before the final result.)
When dimensions are not set, the average score is the sum of the scores for each question divided by the number of questions.
Example Calculation: (2.88.. + 2.75.. + 2.63.. + 2.5..) / 4 = 2.69..
Score Calculation Logic and Example
SurveyMars 360-degree evaluations automatically generate department comparison reports, individual comparison reports, department assessment reports, and individual assessment reports. Below is an explanation of how the scores in these reports are calculated.
The scores in the assessment report are calculated based on the options selected by the evaluators. Therefore, when adding questionnaire items, it is essential to include matrix scale questions and assign appropriate scores to each option. The default option scores provided by SurveyMars range from 1 to 5, and the following explanation uses this 5-point scale for calculations.
The entire calculation process can be summarized as follows:Raw Data → Hierarchical Scores → Single Question Scores → Dimension Scores → Individual Composite Scores → Department Composite Scores.
Example Scenario:
- There are two Subject: James and Tom.
- James has been evaluated by 2 superiors, 3 subordinates, and 5 peers.
- Tom has been evaluated by 1 superior, 6 subordinates, and 3 peers.
- Level weights are set as follows: Superiors 50%, Subordinates 20%, Peers 30%.
- The assessment questionnaire contains 6 questions: the first 2 questions belong to Dimension 1, and the last 4 questions belong to Dimension 2 (with Dimension 1 weighted at 60% and Dimension 2 at 40%).
Calculation Steps
1. Raw Data
The raw data can be downloaded from the backend. The data includes information such as the evaluator, the evaluatee, the evaluation relationship, and the score for each question.
In the example, there are 10 people evaluating James and 10 people evaluating Tom, resulting in a total of 20 data entries, as illustrated below:
2. Hierarchical Scores
the system aggregates all data with the same evaluation relationship for the same evaluatee to calculate an average score. After this calculation, each evaluatee will have only one average score per hierarchical level.
In the example, you will obtain the average scores for James for each question from superiors, subordinates, and peers. The same applies to Tom. In total, the data will retain 6 entries (3 rows for James and 3 rows for Tom), as shown in the table below:
Individual Assessment Report: James's Scores by Hierarchical Level for Each Question.
3. Single Question Scores
The system uses the weights set by the user for superiors, subordinates, and peers to calculate a weighted score for each evaluatee on a single question, resulting in a final score for that question (if no level weights are set, the system calculates a simple average score across levels).
In the example, the weight for superiors is 0.5, for peers is 0.3, and for subordinates is 0.2. This calculation will yield a composite score for James. The same process applies to Tom. Each evaluatee will retain only one entry, resulting in a total of two entries, as shown in the table below:
All Personnel Comparison Report: Scores for Question 1 for James and Tom.
4. Dimension Scores
Dimension scores are calculated by averaging the scores of the questions associated with that dimension. First, the system calculates the dimension score given by "each evaluator" for the evaluatee by averaging the relevant question scores. Then, the dimension scores from "all evaluators" for that evaluatee are summed and averaged to obtain the evaluatee's overall score for that dimension.
All Personnel Comparison Report: Dimension Scores for James and Tom.
5. Individual Score
The individual score is the average of the scores across all dimensions.If the dimensions have different weights, the individual composite score is calculated using these weights.
In the example, after obtaining Zhang San's scores in the two dimensions from the previous steps, the individual score can be easily calculated by averaging or weighting, as shown in the table below:
All Personnel Comparison Report: Individual Scores for James and Tom (With and Without Dimension Weights).
6. Department Score and Overall Average Score
(1) When the evaluatee's department is not set: The overall average score is the mean of all individual scores.
(2) When the evaluatee's department is set: The department score is calculated by averaging all individual scores of members within the department to obtain the final department score.
In summary, the calculation of the assessment report is a process of progressively condensing the raw data:
1. The first step merges data with the same evaluation relationship.
2. The second step combines different evaluation relationships using specified weights.
3. The third step aggregates multiple questions according to their dimensional relationships.
4. The fourth step consolidates multiple dimensions into a single composite score.
FAQ
Q1: How are total scores calculated when dimensions are set in 360-degree assessments?
A: When dimensions are set, the total score is the sum of the individual scores for each dimension. For example, if you have three dimensions (Efficient Execution, Team Collaboration, Responsibility Awareness), the total score would be the sum of the scores for these three dimensions.
Q2: How are total scores calculated when dimensions are not set?
A: When dimensions are not set, the total score is the sum of the scores for each question. For example: 2.88 + 2.75 + 2.63 + 2.5 = 10.75, where each number represents the exact value without rounding.
Q3: How are average scores calculated when dimensions are set?
A: When dimensions are set, the average score is the mean of the scores for each dimension. For example: (2.81 + 2.63 + 2.5) / 3 = 2.65, where the scores for the three dimensions are added together and divided by the number of dimensions.
Q4: What is the calculation process for 360-degree assessment reports?
A: The entire calculation process can be summarized as: Raw Data → Hierarchical Scores → Single Question Scores → Dimension Scores → Individual Composite Scores → Department Composite Scores. This progressive condensation ensures accurate and meaningful assessment results.
Q5: How are department scores calculated when departments are set for evaluatees?
A: When the evaluatee's department is set, the department score is calculated by averaging all individual scores of members within the department to obtain the final department score. This provides a comprehensive view of departmental performance and team dynamics.
