based on the population and sample surveys. In universe surveys, information is collected from every member of the population. Sample surveys being used creates a statistical uncertainty is introduced because the data come from only a portion of the entire population. Ultimately the data provided from sample surveys only gives an approximation of the true value.
What sorts of statistics (e.g., graphical, non-graphical, hypotheses, correlation, averages, etc.) were used in the report? The statistics from the report was presented in maps with percentages, histograms, line graphs, bar graphs, tables and charts, averages and non-graphical comparison data. How was the data distributed? The data was distributed using the indicators. First the data was compared by the current year to the previous year. Then race and gender. Then the data was distributed based on subcategories. How are distribution and variation important in any statistical study? In any statistical study, distribution and variation is extremely. An important characteristic of any set of data is the variation in the data. In some data sets, the data values are concentrated closely near the mean; in other data sets, the data values are more widely spread out from the mean. The variance looks at all the data points and then determines their distribution.

What students are saying

• 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.
