Prediction for 2020 (based on quadratic formula): 25.53% of the children ages (6-11) will be obese
ANALYSIS OF MY MODEL OF OBESE CHILDREN (6-11)
-After graphing these data points, I was not surprised to see an increase of the percent of children obese grow
from the year 1960 to 2008 continue at a steady rate. From all three of my models, this one seemed to be the most
exponential looking. Analyzed in my collection of data, I found that a reason for the increase was from the
in the hours spent in front of the television. Children today at this age watch more television than the children
did 50 years ago. It's rise seemed steady until the year 1980, and then the rate began to increase faster. This is
possibly due to the decrease in demand of physical activities in education, as well as the increase in the number
of fast food outlets throughout the country. Either way, this model displays the strongest growth in obesity among
the three. My prediction of the percent obese in the year 2020, based on my quadratic formula, is that 25.53% of
the children (6-11) will be obese.

Prediction for 2020: 20.34% of the children ages (12-19) will be obese
ANALYSIS OF MY MODEL OF OBESE CHILDREN (12-19)
-This model matched the linear formula closer that I expected. I almost expected to see a more of an exponential
graph from this age group, because the exposure to a wider range of environmental factors are increased at an
older age. I observed that from the years 2000 to 2008, the percentage of obesity was steadily increasing. It
staggers around the 17.4 percentage. This may be due to the creation of baked goods, healthy and calorie conscious
foods created, and more emphasis and awareness taught in the schools of healthy eating habits. There is still no
proof or leads heading towards a future decline in this. My prediction of the percent obese in the year 2020, based
on my linear formula, is that 20.34% of the children (12-19) will be obese.

Prediction for 2020: 39.42% of adults (20+) will be obese
ANALYSIS OF MY MODEL OF OBESE ADULTS (20+)
-My model of the percentage of adults obese from the years 1960-2008 had some dramatic increases. From 1980 to
1995 nearly doubled. This graph is increasing, although seemingly increasing at a slower rate from 2004 to 2008.
Nevertheless, the rate of obesity is still increasing. An important factor in the growth of this surrounds the demand
for faster, more time-saving products (foods). With the hectic life-style of today, this is more relevant than ever.
My prediction of the percent of obese in the year 2020, based on my linear formula, is that 39.42% of all adults (20+)
will be obese.
