The unbiased trimmed mean comes out to 38.64, not 34.64.

The unbiased trimmed mean comes out to 38.64, not 34.64. Very useful post though. I used it to make a python method that calculates trimmed means: https://gist.github.com/anonymous/5864888

TeXification; punctuation and line spacing.

I tried to update the answer using TeX format but I couldn't manage it well. Could you please give me a link which explains how to use TeX style in posts? I have no experience in TeX. | |

@Mehper: just FYI, you can format maths by writing TeX expression in between $ signs. E.g. $X_i$

To remain unbiased, it seems you must remove half of the 4 and half of the 105 for a trimmed mean of (4/2 + 6 + 7 + 11 + 21 + 81 + 90 + 105/2)/7 = 34.64 | |
