Two way ANOVA is an appropriate method to analyze the main effects of and interactions between two factors. Minimum Origin Version Required: Origin 2016 SR0.
Nosing â An edge part of the tread that protrudes over the riser beneath. If it is present, this means that, measured horizontally, the total ârunâ length of the stairs is not simply the sum of the tread lengths, as the treads actually overlap each other slightly.
(Eg :- 13NÂº risers 12NÂº treads.)(The top tread is only a nosing that attaches to the Trimmer Joist at the top of the staircase.) The next thing you have to do is work out the tread size required otherwise known as the going, the going is the measurement from the face of one riser to the face of the next riser.
