11. Quantitative variables are also referred to as continuous or interval variables. 12. Categorical variables consist of separate, indivisible categories. 13. Categorical variables may also be refered to as nominal, ordinal, discrete, or qualitativ 14. A dichotomous variable is one that has only two possible levels or categories 15. Age is a quantitative variable, but one could recode the values so that it would be transformed into a dichotomous variable 16. When conducting a multivariate analysis, the best recommendation is...

Consider the dataset regarding the drop in light percent output (output) and two input variables – bulb surface (qualitative) and length of the operation hours (quantitative). The data is available in a sheet named ‘Problem 3’. Answer the following. (a) Write down the overall model form if one wishes to build a second order model for each value of the qualitative variable (c) Build a regression model showing the 90% confidence ranges of the regression parameters. Write down the mean...

Discrete vs. Continuous Random Variable: You will notice that there is most ikely no mode for the sample data set presented in Table 1. The reason there are not multiple instances of exactly the same value of the random variable is due to the continuous nature of the random variable. Continuous random variables are random variables whose value can take on infinitely many values- the value of which is typically governed by the precision of the device used to measure...
