COMP09015 2019 Research Methods for Data Science
Data science involves exploring problems in particular knowledge domains, identifying how data can be analysed to help solve these problems and building and evaluating appropriate models to achieve insights. To ensure the integrity and accuracy of data science research, it is essential that the student develops a deeper understanding of the fundamentals of research methods and ethics. This module introduces skills needed to develop meaningful research questions within particular problem domains, and to design appropriate research strategies and designs to address these. A critical approach that considers and deals with issues such as methodology suitability, data quality, data validity, data ethics (e.g. data bias, algorithmic bias, privacy) and potential unintended consequences is emphasised. An understanding of both qualitative and quantitative research methods and how these can be applied in a data science context will be developed through examining how data can be gathered and critically analysed, and how the validity of conclusions drawn using particular models can be assessed. Mechanisms for dissemination and communication of research outcomes will also be covered.
On completion of this module the learner will/should be able to;
Undertake a literature search and generate a literature review on a research topic.
Formulate an appropriate research question or hypothesis.
Design and critically apply an appropriate research strategy.
Identify any ethical issues that need to be addressed, and ensure these are integrated into research plans/activities.
Devise and/or utilise methods for data collection and analysis incorporating qualitative and quantitative approaches.
Devise a strategy for evaluation and critical appraisal of research outcomes.
Teaching and Learning Strategies
Lectures introducing key topics, illustrative case studies, demonstrations of tools.
Weekly worksheets, small group discussions, use of ethical toolkits.

ISBN 1506386768 ISBN-13 9781506386768
This best-selling text pioneered the comparison of qualitative, quantitative, and mixed methods research design. For all three approaches, John W. Creswell and new co-author J. David Creswell include a preliminary consideration of philosophical assumptions, key elements of the research process, a review of the literature, an assessment of the use of theory in research applications, and reflections about the importance of writing and ethics in scholarly inquiry. New to this Edition: Updated discussion on designing a proposal for a research project and on the steps in designing a research study Additional content on epistemological and ontological positioning in relation to the research question and chosen methodology and method Additional updates on the transformative worldview Expanded coverage on specific approaches such as case studies, participatory action research, and visual methods Additional information about qualitative and quantitative data analysis, social media, online qualitative methods, and mentoring and reflexivity in qualitative methods Incorporation of action research and program evaluation in mixed methods and coverage of the latest advances in the mixed methods field Additional information about causality and its relationship to statistics in quantitative methods Incorporation of writing discussion sections into each of the three methodologies An invaluable guide for students and researchers across the social and behavioural sciences.
