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)


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)


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


Variable names

• Up to 8 characters (no spaces), beginning with a letter

• Not allowed: ALL AND BY EQ GT LE LT NE NOT OR TO WITH

• Can be:– Short version of item description (as used here), or– Var01, var02, var03 etc. or– Q1a, Q1b, Q2, Q3 etc


Types of measure

• Nominal: described in words – eg. male/female• Ordinal: Ranked: 1, 2, 3 … means 1st, 2nd, 3rd ….• Scale: fully numeric


Variable View

• Information on variables is entered in the SPSS ‘Variable View’ screen


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.

Frequencies

• Simple counts/percentages of variables• Nominal/ordinal: straightforward• Numeric may need to be grouped – see Recode• Frequencies form the basis for a statistical

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

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
