Graphs are useful ways to summarize large amounts of data. They may suggest some kind of trend over time or across experimental groups, they may inspire a hypothesis, or they may tend to argue against a theory or hypothesis that has already been made. They may also be simple observational tools to indicate how a known process is unfolding over time. They are useful tools that have to be used properly. By themselves they are rarely strong enough either to prove or disprove a theory or hypothesis.
a bar graph shows unrelated data, so use one when you are showing unrelated data. :)
We use graphs to visually see the data. Often times trends and patterns can be better determined by graphs than by just looking at lists of numbers.
hmm. . .three types of line graghs are the following . . .?
senora bizub created the bar graghs. she was born in Mexico in 1823/
Depending on your definiton of graph a few are: line, bar, pi-chart, scatter-gram.
yes.Yup. Scientists use algebra all the time, no question. Even biologists.
Scientists use seismographs.
Scientists use graphs to organize data.
Scientists use mainly fossils.
scientists frequently use Celsius
Scientists use an electron accelerator :)
Scientists use data from the past to create a timeline.
