The calculated trimmed mean will be different. For the trimmed mean spreadsheet functions there will be no conversion and the calculated trimmed mean will always be that corresponding to the revised definition. 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.
