bryce's Graphing post

1.bar graphs are best for comparing data across categories but are bad for making sure something accurate
circle graphs are good for showing percent and are bad for having a lot of categories and comparing 2 sets of data
pictographs are good for easily reading and using data sets but arn't good for many categories
double bar graphs are good for comparing two things together but are bad for accuracy
line graphs are good for multiple sets of data but have to be continuous

2. there could be a break in y axis
one bar on a bar graph can look a lot bigger than the other ones even the range isnt far apart
a circle can look inaccurate with two categories percents that are very close together

it doesn't seem fair but i don't know if it is because of the person's race that determined their time in jail.
it doesn't seem fair. I would sentence the homeless man's time for 50-80 days in prison. and I would have sentenced the other person for 8-10 years. Or I would have let the homeless man do community service if he wanted to.
