Softwares like SPSS, NCSS-PASS, STATA and Sysat are some of the widely used.
They can be like calculating the sample size for a proposed study, hypothesis testing
and calculating the power of the study. Familiarity with any one package will suffice to
carry out the most intricate statistical analyses.
Computers are useful not only for statistical analyses, but also to monitor the
accuracy and completeness of the data as they are collected.
5) Role of Computers in Research Dissemination
This phase is the publication of the research study.
Research publishing: The research article is typed in word format and converted to
portable data format (PDF) and stored and/or published in the World Wide Web.
FURTHER USES OF COMPUTERS
Medical record linkage in longitudinal studies: In a more comprehensive way
medical record linkage provides continuous record of individual patients from birth to
death, including illnesses hospitalization, operation, allergies and so on. Prior to the
use of computers, the linking together of different events in an individual's medical
case history was extremely difficult. Individual events (treatment by family doctor,
stay in hospital, etc.) were, and indeed usually still are, recorded separately at
different locations with no systematic procedures to bring together these elements of
a case history into a single record. With computer based recording systems, such
linking becomes more feasible, medical records can be put to better use and
information stored efficiently; moreover, this information can be retrieved more rapidly
than before. Cumulative files for individuals can be compiled and assembled into family
groups, socio-economic categories, and so on, for purposes of analysis. Longitudinal
studies, which involve following up a given group of cohort over a period of time, are
a well established application of the concept of medical record linkage, and the large
and comprehensive computerized databases establishe d through record linkage open
up a wide range of potential research studies.
For performing Meta-analysis and systematic reviews : The results from
systematic reviews are graded as the level I evidence. These are obtained by the
