ivy1994 Posted April 12, 2012 Report Share Posted April 12, 2012 I'm just working on a lab report at the moment where I have to calculate the t-test values for a set of data...I'm looking at the lengths of the internode and leaf in the Wandering Jew plant. One set has been grown in sunlight and the other has been grown in the shade. I manually calculated it the first time and got:Internodes: -27.0879671Leaf length: -25.25046944But then I tried again in Excel and got a different value of...Internodes: 4.97254E-48Leaf length: 2.26466E-44Would anyone be able to help me with interpreting these results because I've just about given up......Thanks in advance!
