Hi,

I encountered a small problem while drawing a graph with Excel 2003.

I entered X axis and Y axis value and plotted the graph and drawn the trend line with zero intercept and found the R (regression)square value.

In the same graph If I entered X axis with some units (say grams), the R square value is reduced and even reduced by adding a units to y axis also.

Please let me why this problem occurs.

Is there a way to correct it.

Thank you,
Sainath
