applications of statistics..
1.experimental design....it is very critical to design an experiment before you coduct it,,,there are different statistical experimental design for it like..CRD,RCBD,Latin square design,Factorial design,Split plt,Split block.....these design are applied in various researches specially in medical and agricultural sciences..they help in replication and randomization.
2.data collection for different experiments related to medical,biological,agricultural,social sciences.
3.Data analysis..
the data pooled for every research is then analysed for getting results,data analysis is specific for specific designs...there are different softwares which can help in analysis like mstat,spss,statistica etc...
the data analysis gives information about ...
a) the presence of certain disease in a population
b) the frequency and abundance of a gene related to the disease.
c) various levels of disease
the f-test,t-test.DMR test,LSD test all help in finiding variance,differences,deviations etc.
d) which plants/varieties are more productive
e) correlation helps in finiding positive/negative relation between two variables.
f)path coefficient analysis helps in relation b/w dependent and independent variables.
g) how mucha trait can be inherited to the offsprings.
h) what is possibility of controlling a genetic disorder.

these are a few of wide applications of stats...further the new methods like bioinformatics and biometry can help in drug design,protein structure prediction etc.
designing og gene chips, oligonucleotides and probes..
