1Vital statistics primarily deals with numerical facts about which of the following?
2In a closed population (no migration), if P₀ = 100,000, live births B = 1,850 and deaths D = 1,680 in a year, what is the population at the end of the year Pₜ?
3In a town, mid-year population was 150,000 and live births during the year were 6,000. The crude birth rate (CBR) per 1,000 is:
4If mid-year population is 80,000 and deaths in the year are 960, the crude death rate (CDR) per 1,000 is:

About the Karnataka II PUC Statistics (KSEAB) Exam
Karnataka II PUC Statistics is the Class 12 Pre-University public examination statistics paper under the Karnataka School Examination and Assessment Board (KSEAB), subject code 31. It assesses the Karnataka II PUC Statistics syllabus: vital statistics (fertility, mortality, growth rates, life tables); index numbers (Laspeyres, Paasche, Fisher, CPI, consistency tests); time series (components, trend by moving averages and least squares); interpolation and extrapolation; theoretical distributions (Bernoulli, binomial, Poisson, hypergeometric, normal, t, χ²); statistical inference (estimation, hypothesis testing, large- and small-sample tests); statistical quality control (X̄, R, np, c charts, acceptance sampling); and operations research (LPP, transportation, games, replacement, EOQ inventory). The official assessment is a mixed theory paper (about 3 hours 15 minutes) with 1-, 2-, 5-, and 10-mark items per blueprint, plus practical work as notified. Fees and exact blueprints are notified by KSEAB / DPUE (kseab.karnataka.gov.in; dpue-exam.karnataka.gov.in). Pass marks are commonly described near ~35% overall with separate floors as notified. The 100 questions on this page are a free English-language multiple-choice study adaptation with explanations and multi-step calculation practice; they are not a full simulation of the official mixed theory paper or practical exam.
Exam sponsor: Karnataka School Examination and Assessment Board (KSEAB). The requirements and fees below concern the certification or admission exam, separate from our free practice resources.
Assessment
Official KSEAB II PUC Statistics (code 31) is assessed as a mixed written theory paper lasting about 3 hours 15 minutes (commonly including reading time), with Part-style questions per the 2025–26 KSEAB blueprint (Vital Statistics; Index Numbers; Time Series Analysis; Interpolation and Extrapolation; Theoretical Distributions; Statistical Inference; Statistical Quality Control; Operations Research), plus practical components as notified (DPUE materials describe theory + practical structure for Statistics). English and Kannada media are typically available. Exact theory–practical splits and attempt rules are as published for the year — confirm circulars on kseab.karnataka.gov.in and dpue-exam.karnataka.gov.in. This practice bank is an English-language MCQ study adaptation for concept and calculation fluency — it does not simulate official attempt limits, long multi-step written solutions, or practical examinations.
Time Limit
About 3 hours 15 minutes (theory; often includes 15 minutes reading time)
Passing Score
Commonly reported as about 35% overall in the subject, with separate theory and practical/internal minima as notified for the year (about a 30–35% careful range depending on circular wording); verify the current pass criteria for your examination year.
Exam / Certification Fees
As notified by KSEAB and paid through PU colleges for regular II PUC sittings (no single fixed public subject fee for all categories).

Vital Statistics
Meaning of demography and vital statistics; census vs registration; CBR, ASFR, GFR, TFR; GRR/NRR; CDR, ASDR, SDR, IMR, NMR, MMR; population equation Pₜ = P₀+(B−D)+(I−E); life-table components.
Index Numbers
Price, quantity, and value indices; simple and weighted construction; Laspeyres, Paasche, Fisher ideal, Marshall–Edgeworth, Dorbish–Bowley, Kelly; TRT and FRT; family-budget and aggregative CPI methods.
Time Series Analysis
Components T, S, C, I; additive vs multiplicative models; trend by graphical, semi-average, moving averages (odd/even centering), and least squares linear/quadratic/exponential; historigram and short-term fluctuations.
Interpolation and Extrapolation
Equal-interval finite differences; binomial expansion and Newton methods; estimating missing values; interpolation within the table vs extrapolation outside the range.
Theoretical Distributions
Bernoulli, binomial, Poisson, and hypergeometric pmfs with mean/variance; fitting and recurrence ideas; normal/SNV, empirical rule; features and uses of χ² and Student’s t.
