Chapter 9 Use of Statistical Tools
Steps in Making a Project
Introduction
Statistical tools are essential for analyzing data related to economic activities such as production, consumption, distribution, and trade. This chapter will guide you through the method of developing a project, which demonstrates how these statistical tools can be practically applied. Conducting a survey and preparing a project report helps in analyzing relevant information and suggesting improvements, whether it's for a product, a service, or a system.
Steps Towards Making a Project
Developing a statistical project involves a series of systematic steps, from identifying the problem to presenting the final conclusions.
1. Identifying a Problem or an Area of Study
The first step is to be clear about what you want to study. The objective of your study will guide the entire process of data collection and analysis. Your area of interest could be the production or sale of a product (like cars or soaps), a civic issue (like water or electricity problems in a specific area), or a social issue (like consumer awareness about their rights).
2. Choice of Target Group
Identifying the target group is crucial for designing an effective study and framing appropriate questions. The target group consists of the individuals on whom you will focus your attention. For example, if your project is about luxury cars, your target group will be middle and higher-income groups. If it's about a consumer product like soap, your target group will be all rural and urban consumers.
3. Collection of Data
The objective of your survey will determine the method of data collection. You may use primary data, secondary data, or a combination of both.
- Primary Data: This is first-hand data collected through methods like personal interviews, mailing questionnaires, or phone/email surveys. If sampling is used, care must be taken to choose a suitable sampling method.
- Secondary Data: This is data that has already been collected by someone else. It is usually used when there is a shortage of time, money, or manpower, and the information is readily available from sources like government reports, research papers, or websites.
4. Organisation and Presentation of Data
After collecting the data, it needs to be processed. This involves organising the raw data and presenting it in a clear and understandable format using tools like tabulation and suitable diagrams (e.g., bar diagrams, pie diagrams, histograms).
5. Analysis and Interpretation
This is the core of the project where statistical tools are applied to the organised data.
- Measures of Central Tendency (like Mean, Median, Mode) are used to calculate the average or typical value.
- Measures of Dispersion (like Standard Deviation, Range) are used to understand the variability or spread of the data.
- Correlation is used to analyze the relationship, if any, between different variables.
6. Conclusion
The final step is to draw meaningful conclusions by analyzing and interpreting the results. Based on the findings, you should provide suggestions or predict future prospects related to the problem under study.
7. Bibliography
In this section, you must mention the details of all the secondary sources (magazines, newspapers, research reports, websites, etc.) that you used for developing your project.
A Sample Project: Studying the Toothpaste Market
Project Objective
