What is Research?
• A systematic means of problem solving (Tuckman 1978)
• 5 key characteristics:
![Page 4: Recognising Research: Approaches & Designs Introduction to Study Skills & Research Methods (HL10040) Dr James Betts FACSM J.Betts@bath.ac.uk @DrBSteamjets.](https://reader035.fdocuments.us/reader035/viewer/2022062216/56649cd65503460f9499dd9a/html5/thumbnails/4.jpg)
What is Research?
1. Systematic – research process
2. Logical – induction/deduction
3. Empirical – evidence based
4. Reductive – generalisation
5. Replicable – methodology.

Analytical Research
• Reviews– A critical account of present understanding
– A meta-analysis is a quantitative method of review
• Historical Research– Accessing both primary (e.g. witnesses) or secondary
(e.g. literature) sources to document past events
• Philosophical Research– Organising existing evidence into a comprehensive
theoretical model
![Page 14: Recognising Research: Approaches & Designs Introduction to Study Skills & Research Methods (HL10040) Dr James Betts FACSM J.Betts@bath.ac.uk @DrBSteamjets.](https://reader035.fdocuments.us/reader035/viewer/2022062216/56649cd65503460f9499dd9a/html5/thumbnails/14.jpg)
Descriptive Research
• Case Study– Accrual of detailed information from an individual
• Survey– Cross-sectional: Status of a various groups at a given
point in time
– Longitudinal: Status of a given group at various points in time
– Correlational: Relationships between variables
Refutable?
![Page 15: Recognising Research: Approaches & Designs Introduction to Study Skills & Research Methods (HL10040) Dr James Betts FACSM J.Betts@bath.ac.uk @DrBSteamjets.](https://reader035.fdocuments.us/reader035/viewer/2022062216/56649cd65503460f9499dd9a/html5/thumbnails/15.jpg)
Correlational Evidence
• When variable X increases, variable Y also increases
• So, does X increase Y?– or does Y increase X?
• Alternatively, does Z increase both X and Y?
Correlations do not infer Causality(and vice versa?)
See inapt use of language: Brown et al (2013)i.e. always Read Primary Lit (inc. actual data)!

Experimental Research• Experimental research involves a direct assessment of
how one variable influences another• This allows the establishment of causality• All extraneous variables must be held constant while a
single variable is manipulated and the effect measured
• Definition of variables:
Independent Variable = this variable is the ‘cause’

• Effective Sampling produces a n which is representative of N
• Note: n is only ever representative of the N it was drawn from, i.e. not necessarily the general population.

Sampling Methods• Random- All members of N have an equal
chance of selection
• Stage- Randomly select a group, then take sample
• Cluster- Select a natural group to sample from
School
Classe.g.
e.g.
e.g. local community

Sampling Methods• Stratified- identify strata and sample accordingly
• Systematic- e.g. every fourth person but starting at a random point
• Opportunity- sample a convenient groupAvoid Researchers!
i.e. Global Pop. Sample (n=100)
= 51% = 51
= 49% = 49

Qualitative?
![Page 45: Recognising Research: Approaches & Designs Introduction to Study Skills & Research Methods (HL10040) Dr James Betts FACSM J.Betts@bath.ac.uk @DrBSteamjets.](https://reader035.fdocuments.us/reader035/viewer/2022062216/56649cd65503460f9499dd9a/html5/thumbnails/45.jpg)
Quantitative versus Qualitative
Quantitative Research Strategy
•Investigation aims to assess a pre-stated theory (Deductive Reasoning)
•Often involves hypothesis testing
•Attempts to minimise the influence of the researcher on the outcome
•Quantitative data infers statistics
•Data collection therefore requires ‘closed’ responses
Qualitative Research Strategy
•Investigation aims to create a novel theory (Inductive Reasoning)
•Researcher becomes an inherent part of the study - ethnography
•Qualitative data infers complex statements or opinions
•Data collection therefore permits ‘open’ responses
![Page 46: Recognising Research: Approaches & Designs Introduction to Study Skills & Research Methods (HL10040) Dr James Betts FACSM J.Betts@bath.ac.uk @DrBSteamjets.](https://reader035.fdocuments.us/reader035/viewer/2022062216/56649cd65503460f9499dd9a/html5/thumbnails/46.jpg)
Choice of Research Strategy…
• Based on:– Epistemology (How should we be attempting to assess
knowledge?) • Positivism = explain a phenomena
• Interpretivism = understand a phenomena
– Ontology (Does the data exist in a tangible or an intangible form?)
• Objectivism = explain independent external outcomes
• Constructionism = understand how social factors interact
![Page 47: Recognising Research: Approaches & Designs Introduction to Study Skills & Research Methods (HL10040) Dr James Betts FACSM J.Betts@bath.ac.uk @DrBSteamjets.](https://reader035.fdocuments.us/reader035/viewer/2022062216/56649cd65503460f9499dd9a/html5/thumbnails/47.jpg)
Choice of Research Strategy…
• Study in the natural sciences often requires a positivistic epistemology and an objectivistic ontology
• Study in the social sciences often requires an interpretive epistemology and a constructionist ontology
• However, it is occasionally possible to combine these strategies by coding qualitative data quantitatively (i.e. Athlete = 1 ; Non-Athlete = 2)
