Elementary Statistics and Computer Application

Paper code: 11050101

**Note: The question paper will be of two parts—Part A (descriptive type questions) and Part B (objective type uestions), evenly distributed over the entire syllabus. The students have to attempt both part A and part B which carry equal weightage (50% each).**

**Theory**

**Unit-1**

Introduction to statistics, limitations of statistics. Basic concepts: Variable statistics, types and sources of data,

classification and tabulation of data, construction of frequency distribution, tables, graphic representation of

data, simple, multiple component and percentage, bar diagram, pie diagram, histogram, frequency polygon

and frequency curve average and measures of location, mean, mode, median, geometric mean, harmonic

mean, percentiles and quadrilles, for raw and grouped data. Dispersion: Range, standard deviation, variance,

coefficient of variation for raw and grouped data. Probability: Basic concept, additive and multiplicative laws.

Theoretical distributions, binominal, poison and normal distributions, sampling, basic concepts, sampling vs.

complete enumeration parameter and statistic, sampling methods, simple random sampling and stratified

random sampling.

**Unit-2**

Tests of Significance: Basic concepts, tests for equality of means, and independent and paired t-tests, chisquare test for application of attributes and test for goodness of fit of Mendalian ratios. Correlation: Scatter

diagram, correlation co-efficient and its properties, regression, fitting of simple linear regression, test of

significance of correlation and regression coefficient. Experimental designs: Basic concepts, completely

randomized design, randomized block design, latin square designs, factorial experiments, basic concepts,

analysis of factorial experiments up to 3 factors – split plot design, strip plot design, long term experiments,

plot size, guard rows.

**Unit-3**

DOS and Windows, MS Word- Features of word processing, creating document and tables and printing of

document, MS Excel-Concept of electronic spreadsheet, creating, editing and saving of spreadsheet, inbuilt

statistical functions and formula bar, MS Power point-preparation, presentation of slides and slide show.

**Unit-4**
