Question 104:

Trimmed mean,

80% trimmed mean = ?
was a question on a homework assignment. When I read my notes the teacher had written 10 values, then eliminated the lowest and highest values,then took the mean of the remaining 8 values.

Wouldn't that make it a 10% trimmed mean? or is it 80% trimmed mean, because 8 numbers remained after truncating 2 values?

Thanks,
Liz

I am confused.
