Survey data analysis and types of research (Fig. 16.1)

A. J. Veal & S. Darcy (2014) Research Methods for Sport Studies and Sport Management: A practical guide. London: Routledge
Explanatory research and causality
• Necessary conditions:• Associations between variables (A changes with B)• Time priority (B happens after A)• Non-spurious relationships (relationships ‘make sense’)• Rationale/theory (there should be an explanation)
A. J. Veal & S. Darcy (2014) Research Methods for Sport Studies and Sport Management: A practical guide. London: Routledge
Spreadsheet analysis (Fig. 16.1)
• Example using data from Campus Sporting Life questionnaire (Fig. 10.21)
• FREQUENCY procedure in Microsoft Excel used to produce:– frequency counts of coded variables– averages for numerical variables (age, spend)
A. J. Veal & S. Darcy (2014) Research Methods for Sport Studies and Sport Management: A practical guide. London: Routledge
Statistical Package for the Social Sciences (SPSS)
• Software package produced by SPSS inc., owned by IBM
• Analysis of questionnaire-based and other data– organised as cases with specified variables
• SPSS is effective and one of the most popular packages. Its use in this book does not imply endorsement as ‘the best’ package.

Information required for each variable in the questionnaire
• Name• Type – numeric, string (letters) or date• Width – max. no. of characters• Decimal places• Label – longer version of name• Values – for coded variables• Missing – blanks, no answer, etc. • Columns – no. of columns in Data View screen (see below)• Alignment – left, right, centre (in Data View)• Measure/data type – nominal, ordinal, scale

A. J. Veal & S. Darcy (2014) Research Methods for Sport Studies and Sport Management: A practical guide. London: Routledge
Variable view screen (Fig. 16.8)
Data View
• Data entered directly on the Data View screen, or
• Can be imported from a spreadsheet file

Data View screen (Fig. 16.9)
Note to teachers• It is not envisaged that SPSS detailed procedures
would be the subject of a PowerPoint presentation: students would benefit most from following the procedures in practical sessions
• A copy of the Campus Sporting Life data files is available on the book website
• However, teachers may wish to discuss the nature/ purpose of the various procedures.
• Slides are therefore included with the outputs from the procedures

Descriptives: N, Minimum, Maximum, Mean & Standard Deviation for each variable.

Multiple Response
• Two types of ‘Multiple Response’• Dichotomy: Q. 2: use of services: 4 ‘yes/no’ variables– Best combined into one table
• Category: Q. 6: Suggestions: up to three responses per respondent = 3 variables– Best combined into one table

Recode• Grouping/Re-grouping variable categories, especially:
– presentational: numerical variables – theoretical eg. 5 categories of tourism or just two: leisure vs
non-leisure?– Comparison – with other research– statistical reasons – see Ch. 17
• Examples:– uncoded, ‘spend’ has 9 different answers (see Appendix
16.1): recode into 4 groups– Student status has 2 F/T and 2 P/T categories: recode into F/T
and P/T

Measures of central tendency: Mean, Median, Mode
• Mean = average • Median = middle value when all cases ranked in order• Mode = most popular value• Only valid with scale and ordinal variables• Options:– Add to ‘Frequencies’ procedure– Use ‘Means’

Crosstabulation
• Table showing relationships between two or more variables
• Table can include one or more of the following:– counts– row %– column %– total % – statistical tests – see Ch. 17
• Procedure: ‘Crosstabs’

Weighting
• Weighting discussed in Ch. 13• ‘Weight cases’ procedure• eg. if Masters students under-sampled:– suppose masters students need to be given a
weight of 1.3– create new variable wt– for Masters students wt = 1.3; all others: wt = 1– In ‘Weight cases’: weight by wt

Graphics
• Types:– bar graph– stacked bar graph– pie chart– line graph– scatter plot
• Different graph types suited to different data types
