It is extremely important for a researcher to clearly define the variables in a study because this helps to determine the type of analysis that can be performed on the data. for example, if a researcher wanted to describe countriescountries based on isbn left parenthesis international standard bookisbn (international standard book number right parenthesis group identifiernumber) group identifier, what level of measurement would the variable "isbn group identifierisbn group identifier" be? now suppose the researcher felt that certain countries who were farthercountries who were farther northnorth received higher identifying numbersidentifying numbers. does the level of measurement of the variable change? if so, how?

David consumes two things: gasoline (g) and bread (b). david's utility function is u(g, b) = 10g^0.25 b^0.75. use the lagrange technique to solve for david's optimal choices of gasoline and bread as a function of the price of gasoline, p_g, the price of bread, p_b, and his income m. with recent decrease in the price of gasoline (maybe due to external shock such as shale gas production) does david increase his consumption of gasoline? for david, how does partial differential g/partial differential p_g depend on his income m? that is, how does david's change in gasoline consumption due to an increase in the price of gasoline depend on his income level? to answer these questions, find the cross-partial derivative, |partial differential^2 g/partial differential m partial differential p_g.
