terminology about errors, accuracy, precision, uncertainty,...

This is a terminology video. What do the concepts error, measurement, true value, accuracy, trueness, precision, repeatability, reproducibility and uncertainty mean? Let's try to clear up some confusion, systematically and with illustrations. This is an excerpt from a talk given at the eSSENCE/EMMC 2019 conference in Uppsala, Sweden on June 4, 2019. The entire talk is available at https://youtu.be/Qcj5ySx_i4M (only via this specific url).
