Correlation Analysis Question wrong, where, function, 1060

svgleeson

Hi All,

I need some help understanding where I am going wrong.

The CFA Level II Quant Section (Page 285) has a data set from the IMF. It uses it to illustrate the Sample Covarience and Standard Deviation. The Sample Data is thus:

X Y
.1166 .0676
.0915 .0519
.1060 .0815
.0575 .0339
.1258 .0758
.0634 .0509

They are calculating the sample corelation coefficient as .8702

When I input the data into the BAII Plus Professional, the STAT function shows r as equaling .8704 (rounded).

WHAT ACCOUNTS FOR THE VALUATION DIFFERENCE BETWEEN THE CFAI AND OUR CALCUATORS?

Okay. Thanks everyone. Best to be precise with this.

It's rounding error. Don't waste your time over 2 pips.

BA 2 PLUS USES SAMPLE CORRELATION .

AS Andrew3032 SAID , i think they used excel

becuase with .8702 covariance would be .00043677

as well in calculator is .0043688
