RRB ALP Technician Percentile based Normalisation
RRB ALP Technician percentile based normalisation is a statistical process that is used to adjust the scores of candidates who appear in the exam in different shifts. The purpose of percentile based calculation is that this method ensures that no candidate is advantaged or disadvantaged due to the difficulty level of the question papers varying across different shifts.
What is the Purpose for RRB ALP Technician Percentile Based Normalisation?
RRB ALP Technician Percentile based normalisation is done since the exam is conducted in multiple shifts. RRB normalisation helps in balancing these differences and provides a fair platform for all candidates by converting raw scores to a standardised scale or percentile scale.
RRB ALP Technician Percentile Based Normalisation Formula
The step-by-step process of RRB ALP Technician Percentile Based Normalisation formula is given below:
- Percentile Scores: Percentile scores represent the relative performance of a candidate compared to others in the same shift. It converts the marks obtained into a scale ranging from 0 to 100.
- The percentile score indicates the percentage of candidates who scored equal to or below a particular score.
- The highest scorer in each shift gets a percentile score of 100.
- The formula for Percentile Score is:
- Use of Percentile Scores: The percentile scores are used to prepare the RRB ALP merit list instead of raw scores. This ensures that candidates from different shifts are assessed on a level playing field. The marks obtained in between the highest and lowest scores are also converted to appropriate Percentiles.
- Calculating Percentile Scores: The raw scores of all candidates from different exam shifts are converted into Percentile Scores. These scores are then combined and referred to as the RRB Scores (or RRC Scores for Level-1 exams). These combined scores are used to compile results and determine the merit list.
- Precision in Calculation: Percentile Scores are calculated up to five decimal places. This level of precision helps avoids ties and ensures a fair ranking.
RRB ALP Technician Percentile Normalisation Method
To determine RRB ALP Technician normalised marks, RRBs select a ‘Base Shift’. This is done on the basis of the highest average marks and a sufficient number of candidates. The normalisation process by RRBs ensures a fair evaluation for all candidates appearing in the exam. It balances the varying difficulty levels across various shifts.
