About this Gig
Is your questionnaire producing dependable results? I will evaluate the reliability and validity of your survey instrument using IBM SPSS and provide clear, decision-ready findings.
Depending on your package, the service can include data screening, Cronbach's alpha, corrected item-total correlations, reliability-if-item-deleted diagnostics, sampling adequacy checks, exploratory factor analysis, factor loadings, and concise interpretation.
You will receive organised SPSS output, professionally formatted tables, and a plain-English summary explaining which items perform well and which may require revision. This service is suitable for researchers, nonprofits, consultants, and businesses conducting pilot studies or assessing established scales.
Please contact me before ordering if your instrument contains multiple constructs, reverse-coded items, or more respondents than the selected package. I provide ethical research support and do not fabricate data.
FAQ
What data do you need?
Please provide the questionnaire, coded dataset in Excel CSV or SPSS format, construct names, and any scoring or reverse-coding instructions.
Can you analyse a pilot study?
Yes. Pilot datasets are ideal for Cronbach alpha, item diagnostics, and preliminary factor analysis when the sample size is appropriate.
Will you explain the findings?
Yes. Every package includes clear interpretation. Standard and Premium include a structured findings summary with recommendations.
