Right, you're not using a table but something out of the stats toolbox, which I don't have.
According to the documentation, for dataset d, it's:
d.Properties.VarNames{2} = 'floorNum';
There's even an example of changing the name right in the doc.

Assuming you're talking about a table (which I'll call T):
T.Properties.VariableNames{2} = 'floorNum';
For more information:
doc 'Table properties'
