Applications of Biostatistics in life sciences
- 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 smoking or 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 Genetical studies: •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/natality rate 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.
