I chose to talk about the Population of China because it contains big numbers which I find are more interesting to calculate. China has the biggest population in the world!

These are my data points starting from the year 1820-2010. As it can be seen, there has been an immense increase between the years 1950-2010. (green to black line). This was do to woman abuse and raping during thous years. After some time, having babies was a normal thing which meant that not having them, would result weird. Now, the majority of Chinese women have 1.7 children. This gives a stable range of children which helps the population to grow.

These are my data points with each of their lines. The purple line is my over all line of best fit.

These are my calculations for my blue line

These are my calculations for my green line

These are my calculations for the black line
