Qualitative Methods working group

Work Group: Qualitative Method Validation Leader: Christoph von Holst (JRC/IRMM) Co-Leader: John Erik Haugen (Nofima) Qualitative methods are understood to be those that provide a measurable answer to a given question. MoniQA aims to establish guidelines for the validation of qualitative methods and the performance of validation studies. Two topics will be addressed: 1) Method performance characteristics of qualitative methods 2) Specific challenges for the validation of qualitative methods including (a) purely qualitative method (evaluation of results based on purely qualitative evaluation – yes/no decisions) and (b) qualitative methods based on a quantitative measurement MoniQA will focus only on qualitative methods using real-world examples of method validation studies to apply statistical assessments. Special emphasis will be given to estimation of the prediction error of the percentage rate of correct results at the estimated level of dosage.
