Findings: I found the central tendencies, the 5-point summary and the standard deviation of both of my variables; including for the variable that has data for 2 years. Interestingly, the variables had some common results. However, there were more differences then similarities, as each calculation had a variety of results. For example, variable X I calculated both years (1990 and 2012) and I knew already that each country had major differences between the two, but I think that affected the results in each step (the central tendencies, the 5-point summary and the standard deviation). It is noticeable to see how the mean and median in 1990 is lower than the mean in 2012, and this carried out through the rest of the next calculations. Comparing these findings to variable Y, I see that there is a tremendous …show more content…

All the results show that the answers for variable Y have larger number than to variable X in 2012 and even larger compared to variable in 1990. Overall the one part that is remotely similar is the box and whisker plot; even though the numbers are not the same, the shapes of each of them are alike. Throughout all the measures, there is a noticeable pattern between the variables. Carbon emission has a larger result than the population per km2 in 2012 and 1990. The best measure to observe and best describes the central tendencies in both variables is the median, because the value is not distorted by the major outliers in the data set. Plus, since there are equal amount of data and both variables have a min lower than 5 and a max in the thousands, it seems fair that the median is the best central tendencies to describe the results; it is the only one that is snot
