Hi, If two individuals measured the same 3 objects and recorded the weight each time, and have slight differences in every one of thier weights, would this be a result of rounding or not setting the scale to 0? (I think it's the latter but need confirmation).

Hi, I'm prepping to take the NYSTCE CST Earth Science exam. I have many study guides (Xam book, Morrison Media's study guide, Teaching solutions success system, reviewing prior high school earth science exams etc.) Does anyone know of a class offered in Putnam or Westchester County; I have not been sucessful in locating one?

Thanks for your reply. I'm actually preparing to take the NYSTCE CST in Earth Science (again, I missed it by 17points). I'm trying to recall some of the multiple choice questions. Here's another one: What is the benefit of re-establishing a mine that has been closed down for many years?

If I were to track weather or climate over the last 25 years, what would be the best graph to use: bar graph, pie chart, line graph or, pictograph. I am struggling between a line graph or bar graph because a line graph usually compares two variables (independent & dependent) where as a bar graph is useful in comparing data about one thing at different times. The later fits; however, I think a line graph is correct?
