A graph
a line graph.
Bar graphs are a way of visually representing data
it depends on what kind of data you are desplaying. if there is only one type of data that is all related and conected, a line graph would be a good thing to use.
Whatever information is in the data in a clear and honest way.
Graphs can mislead people by the way they are prepared. See related links for good examples of misleading graphs. When you see a graph, you are seeing a summary of the data. Sometimes our data is misleading, so the graph is just presenting misleading data. For example, I show a graph of how much men and women make each year at a company. I see men make more every year, while women just stay about the same. Perhaps the company just has one woman working there. Perhaps in her job, there are no salary increases. I can also not start the y-axis at zero, to exagerrate the differences. A chart should include all the data. Excluding some data can result in a misleading graph. However, in a graph showing changes over period of time, the preparer of the graph has to chose how long a period is relavent. If we are explaining global warming, a plot showing 100 years might be good. But a graph of car accidents per year, perhaps 5 years is more reasonable.
No, they are not. You can also organize data in a table or chart as well as a graph.
A textual presentation in statistics is data that is shown in a contextual way. For instance, the presenter may choose to use a pie chart, graph or a table to present his data.
A graph or a chart.
A pie chart or graph presents data in this way.
you can present data in science as many different types of graph: bar chart, pie chart, picto-gram and line graph ( depending on what you are trying to present). also you can present data as a tally chart or even a frequency chart to make the data look more professional and reliable.
