ANIMAL GENETICS AND BREEDING

 UNIT-1  BIOSTATISTICS 

1. Data – definition – Collection of data – Primary and secondary data – Classification

of data – Qualitative and quantitative data.

2.Diagrammatic representation of data – uses and limitations – simple, Multiple, Component and percentage bar diagrams – pie chart

3.Graphical representation – Histogram – Frequency polygon and Frequency curve

4.Measures of averages - Mean – median – mode – geometric mean – harmonic mean –computation of the above statistics for raw and grouped data - merits and demerits - measures of location – percentiles – quartiles - computation of the above statistics for raw and grouped data.

5.Measures of dispersion - Range, Variance -Standard deviation – co-efficient of  variation - computation of the above statistics for raw and grouped data

6.Probability – Basic concepts-trial- event-equally likely- mutually exclusive – independent event, additive and multiplicative laws. Theoretical distributions- discrete and continuous distributions, Binomial distributions-properties.

7.Poisson Distributions - properties, Normal Distributions- properties

8.Sampling

9.Test of significance – Basic concepts – null hypothesis – alternative hypothesis – level of significance – Standard error and its importance – steps in testing

10.T-test

11.Test based on CHI SQUARE distribution

12.Correlation – definition – Scatter diagram -Pearson’s correlation co-efficient – properties of correlation coefficient

13.Regression – definition – fitting of simple linear regression equation – testing the significance of the regression coefficient

14.Design of Experiments

15.Completely Randomized Design (CRD)

16.Randomized Blocks Design (RBD)

17.Latin Square Design
