Normalization of Marks in SBI PO Exam Result

The State Bank of India (SBI) PO Exam is a highly competitive examination conducted for the recruitment of Probationary Officers in the State Bank of India. In order to ensure fairness and equity in the evaluation process, SBI follows a normalization procedure for calculating the final marks of candidates.

What is normalization?

Normalization is a statistical process that is used to adjust the scores of candidates in different sessions of the same examination. It takes into account the variation in the difficulty level of different sets of question papers and aims to provide a level playing field to all candidates.

How is normalization done?

Normalization is done using the equipercentile method, which is a widely accepted technique for comparing scores across different sets of question papers. The following steps are involved in the normalization process:

1. Calculation of percentiles: The raw scores of candidates in each session are converted into percentiles. Percentile indicates the percentage of candidates who have scored equal to or below a particular candidate. For example, if a candidate scores in the 90th percentile, it means that he/she has performed better than 90% of the candidates.

2. Equating the percentiles: The next step is to equate the percentiles across different sessions. This is done by taking into account the difficulty level of each session. The percentile scores are adjusted in such a way that candidates from different sessions with the same percentile scores are considered to have performed equally.

3. Calculation of normalized scores: After equating the percentiles, the normalized scores are calculated. These scores represent the final marks of candidates after taking into account the variation in the difficulty level of different sessions.

Advantages of normalization:

Normalization of marks in the SBI PO Exam result offers several advantages, including:

1. Fairness: It ensures fairness in the evaluation process by providing a level playing field to all candidates, irrespective of the difficulty level of their respective question papers.

2. Elimination of bias: Normalization helps to eliminate any bias that may arise due to variations in the difficulty level of different sets of question papers. It ensures that candidates are evaluated solely on the basis of their performance.

3. Comparison across sessions: Normalization allows for a fair comparison of candidates across different sessions of the same examination. It enables the selection of the most deserving candidates based on their relative performance.

In conclusion, the SBI follows a normalization procedure for calculating the final marks of candidates in the PO Exam. This process ensures fairness, eliminates bias, and allows for a fair comparison of candidates across different sessions. By using the equipercentile method, the difficulty level of question papers is taken into account, and the final normalized scores are calculated accordingly.
