Sensor vs. Lab Measurements for pH, TDS, Temperature, and Density

5.5 KB of statistical comparison data between automated sensor and ISO-calibrated laboratory reference measurements. The dataset, authored by Nadun Salinda, includes mean deviation, 95% confidence intervals, p-values from one-way ANOVA, and significance interpretations for pH, TDS, temperature, and density. It was last updated on May 18, 2026.

Use Cases

• Validate the accuracy of automated sensor systems based on statistical comparisons with laboratory references.
• Assess measurement bias for water quality parameters like pH and TDS based on mean deviation data.
• Perform statistical significance testing for sensor data using the provided ANOVA p-values and confidence intervals.

Strengths

• Includes statistical metrics like mean deviation, 95% confidence intervals, and ANOVA p-values for validation.
• Compares four specific water quality parameters: pH, TDS, temperature, and density.
• Released under a permissive CC-BY-4.0 license for reuse.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The 5.5 KB file size indicates a very limited scope of data.
