Explanation:
By the term investigation (or enquiry) we mean the search for information or knowledge. Statistical investigation, thus, implies search for knowledge with the help of statistical devices like collection, classification, analysis and interpretation, etc. According to Griffin, "Statistical enquiries have always required considerable skill on the part of the statistician, rooted in a broad knowledge of the subject matter area and combined with considerable ingenuity in overcoming practical difficulties." So to apply statistical methods to any problem it is necessary to collect the numerical facts since statistical analysis is not possible without them.
The main steps utilized in a statistical investigation include four components: clarifying the problem and formulating questions or hypotheses that can be answered with the data, designing or creating an appropriate experiment that can collect the data required, finding and using the appropriate techniques needed to.
Statistical investigation is a long and comprehensive process. It extends over vario initial planning to the final preparation of the report. The various stages are:
1. Planning of statistical investigation.
2. Collection of data.
3. Editing of data.
4. Presentation of data.
5. Analysis of data.
6. Interpretation of data.
7. Preparation of the report.
