Inside CAIIB – ABM

CAIIB ABM – December 2026

Module Module

Module A

Module A introduces Statistics and its practical applications in banking, covering data collection, classification, sampling techniques, measures of central tendency and dispersion, skewness, kurtosis, correlation, regression, time series, probability distributions, estimation, linear programming, and simulation. Learners will develop statistical and analytical skills through structured lessons, step-by-step numerical problems, solved examples, revision notes, practice questions, and exam-oriented assessments aligned with the CAIIB ABM syllabus.
