This document discusses research methodology and its importance. It defines research methodology as the systematic way researchers approach problems and find answers and conclusions. It notes there are different types of research methodologies and methods. The document outlines the stages of research methodology from defining objectives to sampling strategy to methods and materials to conclusions. It emphasizes the need for careful planning, such as creating a Gantt chart, to address issues that could cause delays and ensure experiments can be completed on schedule.

- 3. WHAT IS RESEARCH METHODOLOGY Research Methodology is a way to find out the result of a given problem on a specific matter or problem that is also referred as research problem. In Methodology, researcher uses different criteria for solving/searching the given research problem. Different sources use different type of methods for solving the problem. If we think about the word “Methodology”, it is the way of searching or solving the research problem. (Industrial Research Institute, 2010).
- 4. RESEARCH METHODOLOGY AND ITS IMPORTANCE In Research Methodology, researcher always tries to search the given question systematically in our own way and find out all the answers till conclusion. If research does not work systematically on problem, there would be less possibility to find out the final result. For finding or exploring research questions, a researcher faces lot of problems that can be effectively resolved with using correct research methodology (Industrial Research Institute, 2010).

- 9. DESIGN OF SAMPLING 9 Feedback from sampling, analysis and interpretation Select methods for sample preservation Select methods for collecting samples Select appropriate analytical method Select number of samples and time/frequency of sampling Select determinands and sampling positions Definition of objectives
- 10. SAMPLING STRATEGY Samples must be representative of; • the bulk material (body) being sampled • temporal variations • spatial variations Discrete (or Random/Grab) – does not account for variation in spatial environment or time Composite – pooled number of discrete samples Systematic (or Grid/Transect) - a planned sampling strategy to accomplish a specific objective (Pseudo)Continuous – ongoing monitoring to e.g. establish baseline values for the environment and/or evaluate changes
- 11. METHODS & MATERIALS Describe precisely how the experiments are to be done. Proper citations – record author(s), year, journal title, volume, page numbers. Are the experiments ‘DO-ABLE’ here in our laboratories? Discuss with your supervisor! List chemical requirements and place order early!
- 12. WHY NEED PLANNING Prepare a time-line for the project – Gantt chart - must take into account holidays, exams, writing-up, submission dates. Very little time. so preparation must be meticulous – there may not be time for repeat experiments. Experiments must be so designed such that results can be presented either graphically or tabulated and amenable for statistical analyses
- 13. WHY NEED PLANNING (Cont..) Implementation Issues: A lot of assignments, lab reports, mini-projects, site visits, quizzes and tests during semester; Project Title not clear; Project has ≥ 2 Objectives Delays due to: Broken Equipment Strong Demand for Equipment Missing Chemicals Limited Access to Research Journals Limited / no access to Company Data (Confidentiality) Lab not open after working hours Person not contactable.
