Hi Group,

I am in "Microsoft Excel Data Analysis and Business Modeling." Chapter 42,
pg 342-343 and put the R squared value on a chart, which equals .9828. Then i
went to the functions and did RSQ, thinking this would give me the same
answer, but it did not. Maybe I am using the wrong function, although it
indicates that is give the R squared value, but the anser I get is .8386

The data:
Year Sales
1 70
2 183
3 340
4 649
5 1243
6 1979
7 4096
8 6440
9 8459
10 12154
The graph gives one answer, (Format options on the trend line, "display R
squared value on chart") = .9828, but the RSQ function gives .8386.
