Question 1187335


{{{10.0}}}%,{{{7.0}}}%,{{{13.5}}}%,{{{-12.0}}}% 

to calculate arithmetic mean, write percentage as decimal, add all and divide by {{{4}}}

arithmetic {{{mean=(0.10+0.07+0.135-0.12 )/4=0.04625}}} or {{{4.625}}}% 


geometric mean:
Geometric {{{mean=sqrt(product _of _the_ n_ data_ values)}}}, assuming{{{ all}}} data
values are {{{positive}}}

in your case ,{{{0.10}}},{{{0.07}}},{{{0.135}}},{{{-0.12 }}},  geometric mean {{{cannot }}} be calculated

Geometric mean can only be calculated when all numbers have the same sign.
Geometric mean cannot be calculated for negative values.
