For new analyses, the new definition will be applied automatically.

The reported trimmed mean will remain the same. When you selected a 20% trimmed mean in the old version, the report will show that this is now called a 10% trimmed mean. For the summary statistics report, when recalling older analyses, MedCalc will adapt the % value of the trimmed mean. This is in agreement with SPSS, R and other major statistical packages. This was in agreement with Excel - In the new MedCalc version, for a 20% trimming, the program trims 20% at the lower tail and 20% at the higher tail, so 40% in total.
