FCI was started in 1970

FISCAL commission was appointed in 1949

Multiple Cropping Programming was Started in 1966

First irrigation commission was appointed in 1901

first deptt of agriculture was established in 1881

the extension work must be based on the-Need and interest of people

Father of Extension- J paul Leagons

father of Sociology- August Commte

National agricultural innovation project was stared in — 2005

Total number of national bureaux are — six

Formula of coefficient of variance is-SD/Mean x 100

t test is generally used, when sample size is 30

The correlation coefficient lies between – l to + I

The experimental design, which simultaneously control the variation in two directions is known as LSD

The basic principles of field experimentation-I Replication 2 Randomized 3 Local control

The technique of analysis of variance was developed by-R.A. Fisher

If fertility gradient of land is in two directions, the experimental design will be-Latin Square design

the most commonly used measure of control tendency is-Arithmetic mean

Cumulative frequency is also known as — Ogive

The term ‘ Kurtosis ‘ was given by-Karl Pearon (1906)

Laplace used the normal distribution in-Analysis of errors of experiments

the important method of least squares was introduced by-Legendre in 1805

The name ” Normal distribution ” was coined independently by-Peirce Galton and Lexix, (1875)

Normal distribution is also known as-Law of error, law of facility of error, lapace’s seconf law, gaussion law etc.

Generalize mean is also known as-Power mean or Holder mean

The standard deviation is widely used measure of-Variability or disperson

The term standard deviation was first used by-Karl Pearson in 1894

if mean, medium and mode is equal, then skewness will be — zero

Correlation’s are useful because they can indicate a-Predictive relationship

which ANOVA is used when the experimenter want to study the effects of two or more treatment variables-Factorial ANOVA

Which ANOVA is used when the subjects are subjects to repeated measures, in which the same subjects are used for each treatment-Two- Way Anova

The completely randomized design is considered to be most useful in situation where

The experimental units are homogeneous

The experimental are small such as Laboratory experiments

Some experimental units are likely to be destroyed

In field experiments the commonly used design is — RBD

For chi- square test, the minimum sample size should be — 50

Define biometry-It deals with observation with living thing

mean, median and mode are equal in-normal distribution

most frequent number in a data set, is known as-mode.
