The relationship between several independent variables and one dependent variable is shown using __________. a logistic regression b simple linear regression c multiple linear regression d nonlinear regression CORRECT ANSWERS: c multiple linear regression Company A sells its 12,000th unit of the year. With that sale, the company's revenue and cost curves meet. What is this point called? a revenue point b crossover point c cost point d breakeven point CORRECT ANSWERS: d breakeven point Cluster analysis a) determines the variables that should be measured. b) is used to determine the difference in the variable data points. c) determines groups of terms or values based on different classification models. d) groups terms or values based on the process of arranging different points in the datas CORRECT ANSWERS: c) determines groups of terms or values based on different classification models. A classification model is just another way to say cluster or group. It is not possible to do any type of analysis without determining beforehand the variables that are being measured. Cluster analysis does measure the difference in the data points, but it is used to group those points. One does not arrange or change, the different points in a dataset. If you want to test a change to a process or system before implementing it in real time, which tool might you use to emulate it? a regression b simulation c system d application CORRECT ANSWERS: b simulation When there are several distinct populations, __________ can be used to analyze the difference between the various populations with respect to its summary statistics. a analysis of variance b crossover analysis c simple linear regression
