CHSE Odisha Business Mathematics & Statistics study guide
CHSE Odisha Business Mathematics & Statistics · Work through your exam, one topic at a time.
Business Mathematics & Statistics is a paper in the Commerce stream of the Odisha Council of Higher Secondary Education (CHSE) +2 curriculum, typically taken alongside Accountancy, Business Studies and Economics. It is aimed at students who need working mathematical and statistical tools for commerce, accountancy and management study rather than the pure-mathematics route. The CHSE Odisha Business Mathematics & Statistics study guide has 11 sections and about 2,619 words.
01Sets, Relations and Functions
This domain checks fluent use of set notation and operations, counting with Venn diagrams, the definition of a relation as a subset of a Cartesian product, and the function idea of one output per input. Questions often combine a small Venn-diagram count with a domain/range or composite-function item.
301 words, about 2 min02Matrices and Determinants
Matrix questions test order, conformability, special matrices, transpose, determinant evaluation, adjoint and inverse. The exam frequently asks whether a product or inverse exists, or uses a 2×2 inverse to solve two linear equations.
210 words, about 1 min03Permutations and Combinations
This domain tests whether an arrangement (order matters) or a selection (order does not matter) is required. Typical items involve committees, seating, word arrangements with repeated letters, and “at least” conditions.
243 words, about 1 min04Sequence and Series (AP, GP)
Questions test recognition of arithmetic and geometric patterns, use of the nth-term and sum formulas, and simple applications such as instalments, depreciation and growth. The exam may ask for a missing term, a common difference or ratio, or the sum of a finite series.
247 words, about 1 min05Coordinate Geometry: Straight Lines
This domain tests slope, equations of lines in different forms, parallelism and perpendicularity, intersection, and distance from a point to a line. Business applications include cost and revenue lines, break-even points and linear demand.
232 words, about 1 min06Differentiation and Its Applications
Differentiation questions test standard derivatives, product, quotient and chain rules, and economic applications: marginal cost and revenue, slope of a tangent, increasing/decreasing behaviour, and maxima/minima. The exam expects correct notation and a clear second-derivative check where required.
224 words, about 1 min07Integration and Its Applications
Integration questions test antiderivatives, definite integrals, area under a curve, and simple economic applications such as total cost from marginal cost. The exam may also ask for a constant of integration or use substitution.
205 words, about 1 min08Statistics: Measures of Central Tendency and Dispersion
This domain tests mean, median and mode for raw and grouped data, quartiles, range, mean deviation, standard deviation, variance and coefficient of variation. The exam often asks which average is appropriate and how dispersion compares two series.
248 words, about 1 min09Correlation and Regression
Questions test the direction and strength of linear association, Karl Pearson’s coefficient, Spearman’s rank correlation, and the two regression lines. The exam expects interpretation of r , use of means and standard deviations, and prediction from a regression equation.
238 words, about 1 min10Probability and Probability Distributions
This domain tests sample spaces, event operations, addition and multiplication rules, conditional probability, and binomial or Poisson probabilities. The exam frequently uses without-replacement selection and “at least” wording.
208 words, about 1 min11Index Numbers and Time Series
Index-number questions test simple and weighted price indices, especially Laspeyres, Paasche and Fisher, plus interpretation of base and current years. Time-series questions test the components of a series and trend estimation by moving averages or least squares.
