 Analyze one-way and two-way classified data using analysis of variance.

THEORY (30 Hours)

UNIT I (6 Hours)

Definition, scope and limitations of statistics; presentation and summarization of statistical data;
frequency distribution and its graphical representation; measures of central tendency, dispersion,
skewness and kurtosis.

UNIT II (6 Hours)
Definition and concept of probability; additive and multiplication law of probability (without
proof).
UNIT III (6 Hours)

Correlation: Types of correlation and identification through scatter diagram, computation of
correlation coefficient. Linear Regression: Fitting of regression equations; Y on X and X on Y;
properties of correlation and regression coefficients.

UNIT IV (6 Hours)
Elements of sampling: Simple random sampling, sampling distribution, standard error; tests of
significance, large sample test - SND test for means, single sample and two samples; small sample
tests for mean: Student's t-test, Fisher‘s t-test and Paired t-test: F test.
UNIT V (6 Hours)
