Accepted Answer

Welcome back, everyone. In this problem, which level of measurement is most appropriate for the variable amount of money spent by a customer in a store in a day? A says nominal, B ordinal, C interval, and D ratio. No The variable, the amount of money spent by a customer in a day is a numerical measurement. OK? It could be $100 200 dollars, and so on. And it has a true zero point. No money spent means zero, and ratios make sense. In other words, $100 would be twice as much as $50. So this would make it a ratio level, OK? So let's make a note of that. For starters, it's a numerical measurement. Hm. EG maybe $100 200 dollars, and so on. True, it has a true 0, OK. And the ratios in this case make sense. So because of that, this tells us then that. The ratio measurement answer choice D is the most appropriate for this variable. If we review the remaining answer choices, A would be incorrect because for a nominal level of measurement that would this level would represent the categorical data with no inherent order, but that doesn't apply to money spent. In answer choice B, orinal involves ordered categories but doesn't allow for meaningful differences or ratios which doesn't fit with monetary amounts. And in answer to a C, the interval level involves numerical data with equal intervals but no true zero point, which doesn't apply to money as zero money represents a true absence of spending. That's how we are sure that D is the correct answer. Thanks a lot for watching everyone. I hope this video helped.
