Abstract
This review throws the light on applications of statistics in animal sciences, and answering the question of how are statistics playing a vital role in veterinary field and biology .Also it presents different statistical methods that can be used in different studies. The basic statistical concepts should be known. The subject of statistics includes, design of a study that it will provide the biologist with the most information efficiently, Collection of the data by using different sampling methods, and analysis of the data using different statistical tests. It is not necessary to understand the exact methodology of every statistical test used, but it is necessary to understand

The sources of variability are measurement error, genetic and environmental sources. These variability sources must be taken into consideration to make inferences about biological material [3].
Importance of statistics:
Biologists need statistical literacy to present their results in an authoritative form. The precision and accuracy of the measurements are needed by laboratory biologists. Field biologists need special sampling and analytical methods. Data collected may be irregular or asymmetrical, so special treatments may be applied before they can be evaluated.
Statistics have an important role in helping an investigator to describe data, design experiments, and test claims about relationship among things or events of personal interest. Acceptance or rejection of the claims depends on statistics. Statistics never prove anything but they indicate the likelihood of the results of an investigation being the product of chance [1].
Variable in statistics and its types
Variable is a characteristic or measurement of objects or subjects that varies from one object or subject to another. Weight, for instance, is a variable as it varies from one subject to another
