Data analysis for national research project completion is the systematic statistical processing, validation, and interpretation of experimental and survey data required to support project acceptance and conclusion review by funding agencies. This technical article explains the analytical workflow, applicable international and national standards such as ISO 5725 and GB/T 6379, typical data categories, testing items, and quality assurance practices. Understanding these requirements enables research teams to deliver reproducible, defensible datasets and conclusion reports that satisfy formal project acceptance criteria.
Technical Overview
Data analysis for national research project completion refers to the structured evaluation of all quantitative and qualitative data generated during a nationally funded research program, performed at the conclusion (acceptance) stage of the project. The purpose of this analysis is to verify that collected data are complete, accurate, statistically valid, and sufficient to demonstrate that the project objectives and assessment indicators declared in the project proposal have been achieved.
A rigorous completion-stage analysis typically covers data integrity verification, outlier screening, distribution testing, hypothesis testing, regression and correlation modeling, measurement uncertainty evaluation, and reproducibility confirmation. The analytical process is aligned with recognized statistical and metrological standards, including the ISO 5725 series on accuracy of measurement methods and results, the ISO 16269 series on statistical interpretation of data, and the corresponding GB/T national standards. Where independent verification is required, the work may be supported by accredited third-party laboratories operating under ISO/IEC 17025 quality management principles.
The final deliverable is a comprehensive data analysis report that becomes a core annex to the project conclusion documentation, providing the evidentiary basis for expert panel review, achievement appraisal, and archival filing with the funding authority.
Testing Samples
In the context of completion-stage data analysis, the "samples" are the datasets and raw records submitted for statistical processing and verification. Typical categories include:
Laboratory Experimental Data
Raw measurement records from physical, chemical, and materials testing, including replicate readings, calibration curves, instrument output files (spectra, chromatograms, thermograms), and batch test results generated across the project period.
Survey and Questionnaire Data
Structured questionnaire responses, interview records, and scale measurements collected during social science, educational, or public health research, including reliability and validity datasets for survey instruments.
Field and Longitudinal Monitoring Data
Time-series data from environmental monitoring, structural health monitoring, agricultural trials, or equipment operation logs collected at multiple time points and locations over the project duration.
Clinical and Biological Data
Anonymized preclinical or clinical observation records, biological assay results, and dosing or exposure measurements, handled in accordance with applicable ethical and data protection requirements.
Engineering Performance and Validation Data
Prototype test results, process validation records, performance benchmark data, and comparison datasets against reference baselines or literature values.
Testing Items
The analytical scope for project completion is tailored to the declared research objectives and acceptance indicators. Core testing items include:
- Data completeness and integrity verification against the project data management plan
- Outlier detection and statistical treatment of discordant observations per ASTM E178 and related methods
- Normality and distribution testing of datasets per ISO 5479 and GB/T 4882
- Descriptive statistics: mean, median, standard deviation, coefficient of variation, confidence intervals
- Hypothesis testing: t-tests, F-tests, non-parametric tests for significance of research findings
- Analysis of variance (ANOVA) for multi-factor and multi-group experimental designs
- Regression and correlation analysis for modeled relationships between research variables
- Multivariate analysis, including principal component analysis, cluster analysis, and factor analysis where applicable
- Repeatability and reproducibility assessment of measurement methods per ISO 5725 and GB/T 6379
- Measurement uncertainty evaluation in accordance with the ISO/IEC Guide 98 (GUM) framework
- Reliability and validity assessment of survey instruments, including internal consistency analysis
- Numerical rounding and significant figure compliance per GB/T 8170
- Cross-validation of results against project milestones and key performance indicators
Testing Methods
The analytical methodology follows a controlled workflow designed to ensure traceability, reproducibility, and statistical defensibility. Standard references include the ISO 5725 series, ISO 3534 (statistics vocabulary and symbols), the ISO 16269 series, GB/T 6379, GB/T 4889, GB/T 4882, ASTM E178, and ASTM E2282 for defining test results and their validity.
The typical workflow proceeds through the following stages:
- Data audit: systematic review of raw records, metadata, and chain-of-custody documentation to confirm completeness and authenticity
- Data cleaning: identification of missing values, transcription errors, unit inconsistencies, and outliers using standardized statistical criteria
- Method verification: confirmation that measurement methods and their accuracy parameters conform to ISO 5725 and GB/T 6379 requirements
- Statistical analysis: execution of the testing items specified above using validated statistical software with documented version control
- Independent review: dual-analyst verification or blind re-analysis of critical datasets to confirm reproducibility
- Reporting: preparation of the structured analysis report with full documentation of methods, assumptions, software parameters, and results
All analytical outputs are presented with stated confidence levels, uncertainty estimates where applicable, and graphical summaries suitable for direct inclusion in the project conclusion report. Where independent confirmation of experimental data is needed, supplementary verification testing can be arranged through accredited third-party laboratories.
