Study the caselet and associated statistical outputs below and answer ALL the questions that follow: Dr Alexis Madavhu, a business researcher, is currently conducting an empirical investigation into the impact of top talent job satisfaction on business performance of companies listed on the JSE. He suspects that a quantitative variable, top talent job satisfaction, may be predictive of an event, superior business performance. A review of the extant literature revealed that top talent turnover costs mount steeply, arising from the direct replacement costs of talent acquisition, the opportunity costs of vacant positions and time to productivity, and$$more broadly$$lost business performance $($Patro$,2014).$ Dr Madavhu first identified $1,027$ top talent employees $($TTEs$)$ of $358$ JSE$-$listed companies using a quality of hire assessment tool. Secondly, he collected data on $$job satisfaction of top talent employees$$ from $332$ TTEs working at $102$ JSE$-$listed companies using a $110$ rating scale $(1$ being the lowest level of job satisfaction, $10$ being highest level of job satisfaction$).$ Thirdly, he used a Balanced Scorecard to measure the $$business performance$$ of each of the $102$ JSE$-$listed companies. $3\mathrm{.}1.$ Identify Dr Madavhu$$s independent variable $($IV$)$ and dependent variable $($DV$)(2$ marks$)3\mathrm{.}2.$ Identify the levels of measurement of the two variables? $(2$ marks$)$
