Biostatistics is the branch of statistics responsible for the proper interpretation of scientific data generated in Biology, public health and other health sciences. Biostatistics is particularly concerned with disentangling different sources of variation and seeks to distinguish between correlation and causation.

Is a prospective study qualitative or quantitative?

It depends on the design it can be both


What is parametric study?

A parameter is the limit that defines the extent of an activity. Parametric study analyzes parameters.


Correlational study is it cause and effect?

No correlational study is not cause and effect because correlation does not measure cause.


Define multivariate analysis?

Multivariate is the study of random variables which are multidimensional. Multivariate study is based on the statistical principle of multivariate statistics, which involves observation and analysis of more than one statistical variable at a time. In design and analysis, the technique is used to perform trade studies across multiple dimensions while taking into account the effects of all variables on the responses of interest.Multivariate study in MarketingStatistical procedure used in market research where more than one variable is analyzed at the same time. The goal of multivariate study is to identify statistical relationships between the variables, such as the relationship of home and family, or to gauge the dependence of the variables on each other through techniques such as conjoint-analysisor multidimensional scaling. Multivariate study in Dental:A set of techniques used when variation in several variables has to be studied simultaneously. In statistics, multivariate analysis is interpreted as any analytic method that allows simultaneous study of two or more dependent variables.Multivariate study in http://www.answers.com/library/Sports%20Science%20and%20Medicine-cid-9961188A statistical technique in which several dependent variables are analyzed simultaneously. For example, in a study of muscle strength, data may be collected on the age, type of training, and sex of the subjects being studied. In multivariate analysis, the effect of each of these variables can be examined, and also the interaction between them.


What are Disadvantages to Correlation study?

Correlation study is restricted to linear relationships between the variable(s) being studied.
