Ahmedabad: Candidates who challenged the recruitment test for the post of staff nurse alleged that the biased randomisation of questions and continuous repetition in the sequence of answers were aimed at helping a group of candidates who are weak in the Gujarati language. Last month, 50 candidates moved the HC demanding a retest of the Gujarati subject, alleging biased randomisation of questions. They contended that the final answer key followed a fixed answer sequence. There were four different sets of question papers. In one set, the answers to 100 questions occurred in the series ‘A, B, C, D’ in a repetitive continuous series. In three other sets, this repetitive sequence began from the third question. The govt authority opposed the petition. However, the candidates filed an affidavit terming the govt’s affidavit misleading, which tends to divert the court’s attention with “statistical jugglery, which ignores the basic principles of statistical analysis.” The affidavit reads, “The final answer keys and the corresponding question papers are therefore clearly biased and could not occur without deliberate human interference,” the petition reads. It further adds, “The use of a biased answer key also raises the spectre of unfair practices being adopted by the authorities concerned.” The HC is likely to hear this case further on Wednesday.
