'unsafe' 13 of 21 is it a part of statistical testing? no 14 of 21 why? unsafe nature 15 of 21 so what happens to these raw scores? converted to ranks and its these ranks used in calculation 16 of 21 - interval dfgd 17 of 21 based on numerical scales with? units of equal precise sie 18 of 21 why 'better' than ordinal in this sense? more detail preserved 19 of 21 like stopwatches / thermometers why? public scales of meaurement that produce databased on accepted units of time 20 of 21 interval most precise and sophisticated form of data and is necessary for use of what kind of tests? parametric 21 of 21
