Education: A Master's Degree in Statistics/ Mathematical Statistics/ Mathematical Economics/ Econometrics/ Statistics & Informatics from IIT-Kharagpur/ Applied Statistics & Informatics from IIT-Bombay with a minimum of 55% marks or equivalent grade in aggregate of all semesters / years OR Master's Degree in Mathematics with a minimum of 55% marks or an equivalent grade in aggregate of all semesters / years and one year post graduate diploma in Statistics or related subjects from an institute of repute OR M. Stat. Degree of Indian Statistical Institute with a minimum of 55% marks in aggregate of all semesters / years OR Post Graduate Diploma in Business Analytics (PGDBA) jointly offered by ISI Kolkata, IIT Kharagpur and IIM Calcutta with a minimum of 55% marks or equivalent grade in aggregate of .
Selection will be through Online/ Written Examination (WE) and interview. There are 3 papers for the Examination. Paper I Objective Type (on Statistics) with maximum marks of 100 to be attempted in 120 minutes, Paper-II Descriptive Type (on Statistics) (Question paper displayed on computer, answers to be written on paper) with maximum marks of 100 to be attempted in 180 minutes and Paper-III English – Descriptive (To be typed with help of keyboard) with maximum marks of 100 to be attempted in 90 minutes.
Candidates have to secure minimum marks as may be prescribed by the Board. Candidates, who secureminimum aggregate marks in Paper I, as prescribed, will be shortlisted for Paper-II/ Paper III of the examination based on the aggregate marks obtained in Paper-I. The minimum aggregate cut-off marks for being shortlisted for Paper II and Paper III of the examination will be decided by the Board in relation to the number of vacancies. Roll No. of the candidates shortlisted for Paper II and Paper III examination will be published on RBI web-site, tentatively within a week after Paper -I examination.
Paper-I: Questions would cover Probability: Definition of Probability, Standard distribution, Large and small sample theory, Analysis of Variance, Estimation, Testing of Hypotheses, Multivariate analysis and Stochastic Processes.
Paper-II:Questions would cover (i) Probability and Sampling, (ii) Linear Models and Economic Statistics, (iii) Statistical Inference: Estimation, Testing of hypothesis and Nonparametric Test, (iv) Stochastic Processes, (v) Multivariate analysis and (vi) Numerical Analysis and Basic Computer Techniques.
