An Insight in Statistical Techniques and
Design in Agricultural and Applied Research

Department of Agricultural Economics and Management,
Faculty of Agriculture, University of Swaziland, Swaziland
Abstract: Advance applied science researches have experienced a dramatic change in knowledge and an exponential increase in technology. A lot of these technical developments involve agricultural researches and these researches deal with groups rather than individual cases and usually field and experimental study.
The goal of applied research is to provide data to support existing knowledge by filling information gaps or develop new methods. Agricultural research requires proper study design, management, data collection and analysis to obtain statistically sound results. Agricultural researchers and scientists have an important role to play in the agricultural production and development of a nation. In view of the day to day radical changes in agricultural research, the scenario is becoming tough for agricultural scientists and associated scholars.
Statistical science is concerned with the aspect of theory of design of experiments and sample investigation and drawing valid inferences from using various statistical methods. The statisticians design the experiments, trials and analyze the data and interpret the facts. Statistical design and technique helps to describe the involvement of complex phenomena and behavior of agricultural growth. The impact of associated factor can be analyzed with the help of simple statistical design, sampling techniques with inferential statistics.
The techniques of drawing valid interpretation depend on how the data has been gathered and also depending upon the research objective. This paper describes the basic concept of statistical research

    An experiment establishes the relationship through manipulation of the study sample. For an accurate estimate of the relationship between variables, an experiment may need only tens of subjects. Experimental designs are often called true experimental research which can be identified by three characteristics: (1) pre-posttest design, (2) a treatment group and a control group, and (3) random assignment of study participants.

    Statistical data dates back to as early as Ancient Greek time, where it was introduced by John Graunt, William Petty and Pascal in the 16th century. It was then re-introduced by Gottfriend Achenwall in the 17th century. This was a very exciting time for scientists, astronomers and physicists alike as it raised the confidence and knowing that the laws of nature were not of divine intervention. As the years went on, new mathematical discoveries were made such as census data, economy, mortality demographics, and the International Statistical Congresses, which all led to changing its name to “statistics”.…
