2.C Raw Quantitative Results

Use the table below as an example on how to submit raw quantitative data related to the test results. Please add according to your testing design the sample numbers, flour sub-sample numbers, and measurement numbers (replicates) in an Excel sheet. Please respect the column order. It is very important that the ISTA sample number of the sample label is reported in the first column.

Example: Sample number 1 to 3 are divided into two flour sub-sample. Each sub-sample is measured three times.

|Unit |      |

|sample # |flour sub-sample |measurement |test results |

| |# |# (Replicates) | |
