Survey data analysis: SPSS export, weighting, indices
When you open answers in a statistical program, you don't have to define which column belongs to which question, or what each number means. The file already knows. When raw answers are not enough, build your own measurement model: compute an index, balance the sample, and read the difference between groups with confidence intervals.
A researcher opening the file six months from now will understand every variable immediately, without asking questions.
Readable variable names, question labels, value labels, and missing-value codes are already built inside the .sav file. Descriptive variable names are generated automatically by AI.
A complete codebook document explaining each variable, its original question wording, measurement scale, and all value codes.
A structured flow map documenting which respondent path skipped which questions and how conditional branches were routed.
A clean, UTF-8 CSV table that opens seamlessly in Excel, R, Python, Stata, or your preferred quantitative tool.
Empty cells declare why they are empty: skipped due to logic (−99), displayed but left blank (−98), or actively declined (−97). All three are defined as user-missing in SPSS so they never distort mean averages.
Even when measuring reciprocal attitudes between two distinct groups, all answers occupy the same shared variables with clean group identifiers.
Spoken answers are transcribed by AI into clean text columns alongside audio links, ready for qualitative thematic coding.
Compute custom composite indices, scale scores, and weighted metrics with statistical rigor.
Link individual items to latent concepts and overall dimensions; invert reverse-coded items and compute standardized index scores.
If sample demographics skew away from census targets, apply post-stratification weights with automatic trimming of extreme outliers.
Evaluate the statistical significance of gaps between subgroups with automatic 95% confidence intervals and sample size warnings.
