(Pronounced jee - nee ) Measure of inequality between various data points. E.g.: Ineuqality measures the display between a percentage of population and the percentage of resources As Inequality increases as the disparity increases. If a single person holds all of a given resource, inequality is at a maximum. If all persons hold the same p minimum. Gini coefficient is based on the Lorenz curve application in economics. An equality diagonal represents perfect equality: at every point, cumulative population equals cumulative income. The Lorenz curve measures the actual distribution of income. A - Equality Diagonal Population = Income B - Lorenz Curve C - Difference between Equality and Reality

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
