Hypotheses testing

Null hypothesis	Measure	Findings
H01	PEOU	H01 was rejected in favor of H1. The reported PEOU of the extended notation was significantly higher (p = 0.003) when compared to the standardized one
H02	PU	H02 failed to reject. No significant differences were indicated between the reported PU means of standardized and extended notation (p = 0.110)
H03	ITU	H03 failed to reject. No significant differences were indicated between the reported ITU means of standardized and extended notation (p = 0.689)
H04	t_m	H04 failed to reject. No significant differences were found between the times spent creating diagrams (t_m) in standardized and extended notation (p = 0.078)
H05	t_i	H05 rejected. Time spent interpreting the diagram, modeled in standardized notation (t_i) was significantly lower when compared to the extended one (p = 0.001)
H06	E_m	H06 rejected. Significantly more mistakes (E_m) were generated when creating diagrams in extended notation in relation to the standardized one. (p < 0.001)
H07	E_i	H07 was rejected in favor of H7. Significantly more mistakes (E_i) were generated when answering statements relating to diagrams created in standardized notation in relation to the extended one (p < 0.001)
