Applications of Biostatistics in life sciences

Biostatistics is an application of statistical methods for solving problem in biology.
It is used in different disciplines of life sciences. The applications of biostatistics are as follows:
1. In medicine
2. In Environment
3.In human heath
4. In Ecological studies

1. Applications of Biostatistics
Mr. Suraj D. Gabale

2. 1.In physiology and medicine:
To define what is normal or healthy in a population.
To find limits of normality in variables such as weight, pulse
rate etc. in a population.
To find an association between two attributes such as cancer
and smokingor dengue and social class.

3. 2. In phamacology:
To find out the action of drug.
A drug is given to animals or humans to see the changes
produced are due to the drug or by chance.
To compare the action of two different drugs or two successive
dosage of the same drug.
To find out relative potency of a new drug with respect to a
standard drug.

4. 3. In Geneticalstudies:
•Studying genetic structure o population and changes occurring
over generations due to mutation, migration and selection.
•To study small population size and its consequence on
breeding.
•Most common areas where statistical methods are used-
a. Human genome project
b. Linkage analysis
c. Sequencing

5. 4. Statistical Ecology:
•To predict total number of species in the whole population
from the observed number of species in the sample
•To study mortality/natalityrate in a population
•To study species richness or species abundance.

6. 5. In Environmental management:
•To understand relationship between processes in environmental
biology and its management.
•Regular monitoring to detect changes in environment.
•To conclude effectiveness of biological waste treatment
techniques.
