Water Hardness Titration Data from Citizen and Expert Scientists

122 citizen scientists and 18 experts performed complexometric titrations to measure drinking water hardness. The study compares the accuracy and precision of citizen-collected data against expert results, validating a laboratory method for citizen science projects. The dataset was published by Jan E. Kath in 2026.

Use Cases

• Compare water hardness measurement accuracy between citizen and expert groups using titration endpoint volumes.
• Analyze the impact of a visual marker aid on burette reading precision for citizen scientist data.
• Assess measurement variability by examining repeated individual titration results from participants.
• Validate a quantitative laboratory protocol for water analysis using data from 79 citizens in a second trial.

Strengths

• Direct comparison of data from 122 citizen scientists and 18 experts using the same method.
• Includes results from a second group of 79 citizens for method improvement validation.

Limitations

• Very small dataset at 24.1 KB, indicating limited sample size and scope.
• Specific row count, column names, and measurement features are not provided.
