Complete Guide to Cleaning Medical Education Research Data with SPSS

Dr. Emily Rodriguez faced a big challenge in her research lab at Massachusetts General Hospital. She had messy, unreliable data that could ruin her study on patient outcomes¹. This moment showed how crucial data cleaning is in medical research.

Aspect	Key Information
Definition	Data cleaning in medical education research refers to the systematic process of detecting, diagnosing, and editing or removing inaccuracies, inconsistencies, and incompleteness in educational assessment and evaluation datasets. This process involves identifying invalid entries, handling missing values, detecting outliers, validating measurement scales, and ensuring data integrity. The primary purpose is to create a reliable, analysis-ready dataset that accurately represents educational interventions, learner performance, and assessment outcomes, thereby enhancing the validity of statistical analyses and research conclusions in medical education studies.
Mathematical Foundation	Data cleaning relies on several statistical principles and techniques: Z-scores for univariate outlier detection: \[ z_i = \frac{x_i – \bar{x}}{s} \] Mahalanobis distance for multivariate outliers: \[ D^2 = (x – \mu)^T \Sigma^{-1} (x – \mu) \] Little’s MCAR test for missing data patterns: \[ \chi^2 = \sum_{j=1}^{p} \sum_{k=1}^{p} \sum_{i=1}^{n} \frac{(r_{ij} – \bar{r}_j)(r_{ik} – \bar{r}_k)}{s_{jk}} \] Cronbach’s alpha for scale reliability: \[ \alpha = \frac{k}{k-1} \left(1 – \frac{\sum_{i=1}^{k} \sigma_{y_i}^2}{\sigma_x^2}\right) \] Intraclass correlation coefficient for rater reliability: \[ ICC = \frac{\sigma_b^2}{\sigma_b^2 + \sigma_w^2} \] Box-Cox transformation for normalizing skewed distributions: \[ y_i(\lambda) = \begin{cases} \frac{y_i^\lambda – 1}{\lambda} & \text{if } \lambda \neq 0 \\ \ln(y_i) & \text{if } \lambda = 0 \end{cases} \]
Assumptions	Data structure understanding: Researchers must have comprehensive knowledge of the expected data structure, including variable types (nominal, ordinal, interval, ratio), valid ranges for educational assessments, and logical relationships between variables (e.g., pre-test scores cannot exceed maximum possible points). Missing data mechanisms: Appropriate handling of missing data requires understanding whether values are Missing Completely At Random (MCAR), Missing At Random (MAR), or Missing Not At Random (MNAR), which is particularly important in longitudinal educational studies with differential attrition. Outlier definition context: What constitutes an outlier depends on the specific educational construct being measured; extreme values may represent legitimate educational outcomes (e.g., exceptionally high performers) rather than errors. Measurement invariance: When cleaning data from different subgroups (e.g., different training sites, specialties, or cultural contexts), the measurement properties of assessment instruments should be equivalent across these groups for valid comparisons. Documentation integrity: Complete and accurate documentation of all data cleaning decisions and procedures is necessary for research transparency, reproducibility, and defensibility of educational outcomes reporting.
Implementation	SPSS Data Cleaning Workflow for Medical Education Data: Initial Data Inspection: `FREQUENCIES VARIABLES=ALL.` or `DESCRIPTIVES VARIABLES=exam_scores clinical_ratings /STATISTICS=MEAN STDDEV MIN MAX.` Variable Definition and Labeling: `VARIABLE LABELS student_id "Unique student identifier".` `VALUE LABELS gender 1 "Male" 2 "Female" 3 "Non-binary" 4 "Prefer not to say".` `VALUE LABELS year_of_training 1 "First year" 2 "Second year" 3 "Third year" 4 "Fourth year".` Missing Value Identification: `MISSING VALUES exam_score osce_score (999).` `EXAMINE VARIABLES=ALL /PLOT NONE /PERCENTILES(5,10,25,50,75,90,95) /STATISTICS DESCRIPTIVES.` `SORT CASES BY student_id.` `AGGREGATE OUTFILE=* MODE=ADDVARIABLES /BREAK=student_id /n_missing=NMISS(exam1 TO exam10).` Missing Value Analysis: `MULTIPLE IMPUTATION exam1 TO exam10 /IMPUTE METHOD=AUTO NIMPUTATIONS=5.` or `MVA VARIABLES=ALL /EM (TOLERANCE=0.001 CONVERGENCE=0.0001 ITERATIONS=25).` Outlier Detection: `DESCRIPTIVES VARIABLES=exam1 TO exam10 /SAVE.` (Creates z-scores) `COMPUTE flag_outlier = 0.` `IF (ABS(Zexam1) > 3.29 OR ABS(Zexam2) > 3.29) flag_outlier = 1.` `REGRESSION /DEPENDENT=dummy /METHOD=ENTER exam1 TO exam10 /SAVE MAHAL.` (Mahalanobis distance) Scale Validation: `RELIABILITY /VARIABLES=item1 item2 item3 item4 item5 /SCALE('Clinical Competence Scale') ALL /MODEL=ALPHA /STATISTICS=DESCRIPTIVE SCALE CORR.` `FACTOR /VARIABLES item1 item2 item3 item4 item5 /CRITERIA MINEIGEN(1) ITERATE(25) /EXTRACTION PC /ROTATION VARIMAX /METHOD=CORRELATION.` Data Transformation: `EXAMINE VARIABLES=exam_score /PLOT HISTOGRAM NPPLOT.` (Check normality) `COMPUTE log_exam_score = LG10(exam_score).` `COMPUTE sqrt_exam_score = SQRT(exam_score).` `RECODE feedback_rating (1=5) (2=4) (3=3) (4=2) (5=1) INTO feedback_rev.` Scale Construction: `COMPUTE competence_score = MEAN(item1, item2, item3, item4, item5).` `COMPUTE competence_score = MEAN.3(item1, item2, item3, item4, item5).` (Allowing up to 2 missing items) Data Validation: `IF (exam_score < 0 OR exam_score > 100) flag_exam = 1.` `IF (post_score < pre_score) flag_inconsistent = 1.` `FREQUENCIES VARIABLES=flag_exam flag_inconsistent.` Documentation: `COMMENT This dataset was cleaned on [date]. Missing values were imputed using [method].` `SAVE OUTFILE='cleaned_medical_education_data.sav' /COMPRESSED.`
Interpretation	When interpreting the results of data cleaning procedures in SPSS for medical education data: Missing Data Patterns: Evaluate the extent and pattern of missingness. Little's MCAR test p-value > 0.05 suggests data are missing completely at random. For educational assessments, examine if missing data correlates with performance levels (e.g., weaker students missing more assessments), which would indicate MAR or MNAR patterns requiring more sophisticated imputation approaches. Outlier Impact: Compare analyses with and without identified outliers, particularly for high-stakes assessments. Document justification for any outlier treatment based on both statistical criteria (e.g., z > 3.29) and educational context (e.g., confirmed data entry errors vs. legitimate extreme performances). Report sensitivity analyses when outlier handling affects conclusions. Scale Reliability: Interpret Cronbach's alpha values in context of assessment purpose: for high-stakes decisions, α > 0.8 is desirable; for formative assessments, α > 0.7 may be acceptable. Examine item-total correlations (ideally > 0.3) and "alpha if item deleted" values to identify problematic items in educational measurement instruments. Factor Structure: When validating educational assessment tools, examine factor loadings (typically meaningful above 0.4) and total variance explained (ideally > 60%). Ensure factor structure aligns with theoretical constructs being measured (e.g., knowledge, skills, attitudes domains in competency assessments). Transformation Effects: Assess normality improvements through skewness and kurtosis values (ideally between -1 and +1) and visual inspection of Q-Q plots before and after transformations. Report both raw and transformed analyses if conclusions differ, particularly for educational outcome measures where interpretability is crucial. Inter-rater Reliability: For observational assessments with multiple raters, interpret ICC values: < 0.5 indicates poor reliability, 0.5-0.75 moderate reliability, 0.75-0.9 good reliability, and > 0.9 excellent reliability. Address systematic rater differences through recalibration or statistical adjustment.
Common Applications	OSCE and Clinical Skills Assessment: Cleaning standardized patient encounter data, including checklist items, global ratings, and timing metrics; handling multiple rater assessments; identifying systematic station or rater biases; creating composite performance scores across stations. Written Examination Analysis: Processing multiple-choice question data; identifying problematic items through item analysis; handling different examination versions; equating scores across cohorts; creating standardized scores for progression decisions. Longitudinal Performance Tracking: Cleaning repeated measures data from training portfolios; handling missing assessment points; identifying unusual performance trajectories; creating growth curves for competency development over training periods. Educational Intervention Studies: Preparing pre-post assessment data; handling differential attrition in experimental designs; creating change scores; matching participants across intervention and control conditions; processing survey responses on educational satisfaction. Multi-source Feedback Data: Cleaning 360-degree assessment data from multiple evaluators (peers, patients, supervisors); identifying systematic rater effects; handling varying numbers of evaluations per trainee; creating reliable composite feedback scores.
Limitations & Alternatives	Limited automation capabilities: SPSS requires manual specification of many cleaning procedures, which can be time-consuming for large educational datasets with complex structures. Alternatives: R with tidyverse packages offers more programmable approaches through data cleaning pipelines; Python with pandas provides flexible data manipulation for automated cleaning workflows. Advanced imputation limitations: While SPSS offers multiple imputation, it has limited options for specialized imputation methods relevant to educational data structures (e.g., hierarchical data from multiple training sites). Alternatives: The mice package in R provides more comprehensive imputation approaches including predictive mean matching and multilevel imputation models. Restricted handling of nested data: Medical education data often has complex hierarchical structures (students nested within cohorts within programs) that SPSS handles less elegantly. Alternatives: R's lme4 package or Stata's mixed command offer more sophisticated approaches for cleaning and preparing multilevel educational data. Reproducibility challenges: SPSS point-and-click interface can lead to undocumented cleaning steps. Alternatives: R Markdown or Jupyter notebooks enable integrated code, documentation, and results for transparent, reproducible data cleaning workflows that can be shared with educational research collaborators.
Reporting Standards	When reporting data cleaning procedures in medical education publications: Provide a detailed data screening section in the Methods, including sample size before and after cleaning and specific criteria used for case inclusion/exclusion in educational assessments. Report the extent and pattern of missing data (percentage per variable and overall), the missing data mechanism determination (MCAR, MAR, MNAR), and the specific imputation or handling method employed, particularly for longitudinal educational studies. Document outlier identification criteria (e.g., z-score thresholds, Mahalanobis distance cutoffs), number of outliers detected, and justification for the chosen handling approach (retention, removal, winsorization, transformation). Report psychometric properties of all educational measurement instruments after cleaning, including reliability coefficients (Cronbach's alpha), inter-rater reliability metrics (ICC, kappa), and validity evidence (factor structure, correlations with external criteria). Describe all variable transformations applied to address non-normality or other distribution issues, including the specific mathematical transformations used and their impact on interpretation of educational outcomes. For high-stakes assessments, report standard errors of measurement and confidence intervals around key performance metrics to acknowledge measurement uncertainty after data cleaning. Include a data availability statement indicating where and how other researchers can access the raw and/or cleaned dataset, in accordance with educational research transparency principles and institutional review board requirements.
Common Statistical Errors	Our Manuscript Statistical Review service frequently identifies these errors in medical education data cleaning: Inappropriate handling of missing data: Using listwise deletion without assessing missingness patterns, leading to biased samples and reduced statistical power. This is particularly problematic in longitudinal educational studies where systematic attrition occurs (e.g., lower-performing students dropping out). Scale construction without validation: Creating composite scores from educational assessment items without verifying internal consistency, factor structure, or measurement invariance across different learner populations or training contexts. Arbitrary outlier removal: Removing outliers based solely on statistical criteria without considering their educational significance or investigating potential valid extreme responses (e.g., exceptionally high or low performers). Ignoring nested data structures: Failing to account for clustering effects when cleaning data from multiple cohorts, training sites, or raters, which can mask important contextual patterns in educational outcomes. Undocumented data transformations: Applying transformations to normalize distributions without reporting both raw and transformed analyses, making it difficult for readers to interpret the practical significance of educational outcomes. Inconsistent handling of Likert-type data: Treating ordinal educational rating scales inconsistently as either categorical or continuous variables within the same analysis, or inappropriately calculating means for highly skewed rating distributions.
