is there a function im missing somewhere on either the ba2 plus pro or hp 12c that would allow for quicker computations of weighted averages? its so nice when studying at a computer to be able to quickly =sumproduct these things and sadly thats not an option on the exam作者: canadiananalyst 时间: 2011-7-11 19:29
It is there! look at the blue lettering on key "6" it is Xw for weighted average, for example:
value1 enter weight-Factor1 and Sigma Plus key
value2 enter weight-Factor2 and Sigma Plus key
value2 enter weight-Factor2 and Sigma Plus key
then press g+6作者: mar350 时间: 2011-7-11 19:29
