The data, collected for research, has to be processed, analyzed and interpreted to develop a solution to the research question.
Data analysis is a practice in which unorganized or unfinished data  is ordered and organized so that useful information can be extracted from it.
It is the most enjoyable part of carrying out the research since after all of the hard works and waiting the researcher gets the chance to find out the answers. So analyzing the data and interpreting the results are the ârewardâ for the work of collecting the data.
This was a presentation that was carried out in our research method class by our group. It will be useful for PHD and master students quantitative and qualitative method. It consist sample definition, purpose of sampling, stages in the selection of a sample, types of sampling in quantitative researches, types of sampling in qualitative researches, and ethical Considerations in Data Collection.

Data analysis means the ordering, manipulating, and summarizing of data to obtain answers to research questions. Its purpose is to reduce data to intelligible and interpretable form so that the relations of research problems can be studied and tested.

Introduction to Epidemiology Course Project
Detailed Article Critique
Reading, interpreting, and judging the value of epidemiologic literature is a skill that you will exercise throughout your academic career in public health and beyond. To help prepare you for your thesis or capstone experience as well as future coursework, your project this term involves writing a detailed critique of an article. (See link in blackboard.) Construct your critique using complete paragraphs. DO NOT present your critique as an outline.
Please consult the table on the next page to ensure that your review includes the required major elements for this assignment. We will use this table in our evaluation of your project. Each element is worth a specified number of points. Please understand that full credit will not be awarded for simply mentioning each element. You must justify your assessment. For example, you cannot simply state, âThe authors justified the importance of their study.â You need to point out how the authors did or did not meet each criterion. Your critique should not be longer than 4-6 pages double-spaced with one-inch margins. There is no minimum page requirement.
For additional assistance, please refer to the article by Young et al. (2009) that is also posted in Blackboard along with the article that you are to review.

Analysis:
¡ Describe the data analysis plan overall.
¡ Critique the analysis plan by addressing the following:
¡ Is the analysis appropriate for the study design (considering you level of statistical knowledge)? Was potential confounding addressed in the analysis stage? If so, how?
¡ Are the tables and graphs well organized and labeled? Do the tables and graphs provide enough data for reader to draw their own conclusions (e.g. do they stand alone?)?
¡ Are the findings within the tables/figures consistent? Is each table/figure consistent with the text and other tables/figures?
¡ Can the findings be attributed simply to chance?

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Â
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
Â
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasnât one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
The Indian economy is classified into different sectors to simplify the analysis and understanding of economic activities. For Class 10, it's essential to grasp the sectors of the Indian economy, understand their characteristics, and recognize their importance. This guide will provide detailed notes on the Sectors of the Indian Economy Class 10, using specific long-tail keywords to enhance comprehension.

īData collection begins only after a research
problem has been defined and research
design finalized.
īPrimary data are collected for the first time,
hence original in character.
īSecondary data are those which have
already been collected by someone else and
have already been passed through statistical
process.

does not participate in the situation and
collects data by observing behaviour
without interacting with participants.
ī¨ Mechanical observation: People or
situations are to be observed in a closed
setting through mechanical devices.

ī¨ Unstructured interview: Neither the
questions not the answers are pre-
determined. Questions can be changed or
adopted to meet respondentâs
understanding. Does not offer a restricted,
pre-set range of answers.
ī¨ Semi-structured interview: Includes partly
open-ended and closed-ended questions.
Involves both give and receive information.
