STATISTICS LAB-I
Credit Units: 02
Course Objective:
The purpose of the course is to develop knowledge of the fundamental Statistical tools to handle
quantitative and qualitative data. The application of these tools lies with the problems encountered in
decision making. The students will be able to distinguish between probability models appropriate to
different chance events and calculate probability according to these methods.
Course Contents:
1.
Probability Theory-I: Problems based on Discrete and Continuous random variables; workout joint
distribution, marginal and conditional distributions of two random variables, Problems on
independence of random variables, expectation of sum of random variables and product of independent
random variables, conditional expectation, problems based on moments and mgfs.
2.
Statistical Methodology-I: problems based on the presentation of data: classification, tabulation,
diagrammatic & graphical representation of grouped data, frequency distributions, cumulative
frequency distributions and their graphical representations using histogram, frequency polygon and
ogives.
3.
Problems based on measure of central tendency and dispersion, Moments and factorial moments.
Shephard’s correction for moments, Skewness and Kurtosis Measures based on quartiles, problems of
curve fitting using method of least squares.
4.
Calculation of correlation and regression, rank Correlation (Spearman’s and Kendall’s measure), Intraclass correlation, correlation ratio, Partial and Multiple Correlation & Multiple Regression for
trivariate data.
5.
Association of attributes, Independence, Measure of association for 2x2 table, Chi-square, Karl
Pearson’s and Tschuprow’s coefficient of association.
