Because it is easier to see the differences and variations between the results in a graph than in a table.
to tell the difference from different trials
a psychrometer or two thermometers
You need a seismometer for each axis of motion. As such it takes three seismometers.
In The Text It Says That, "Because the country is so large, and Earth's atmosphere is constantly changing, we need data from many stations to make accurate forecasts. "
You need the graph home-slice
Well it depends if it lies on a major fault zone.
you should create a data chart because you can look back and see what went on at each step of the experiment, and i have all my data there to make any calculations i need to do after.
Yes it is. They need to keep records of experiments, like the process of the experiment, so they can repeat it again, and the results. This helps in further research they will do and that other scientists may do. Science is all about gaining and testing knowledge, so it is critical that they record their data.
An answer to your hypothesis supported by your experiment and data from previous experiment's about the same idea
Do the experiment again and again to confirm the data is correct If the data is consistent then your hypothesis is wrong and you need to think of a new one that fits the data.
depends on the experiment - more information required
Follow the Scientific Method when attempting to perform any experiment.

To give final result to our observation
Without the data or the requirements nothing can be done
Data obtained from an experiment is the results you got from whatever test or experiment you did. Data obtained for a research paper is the information you got from your research. Basically, it is the data/info/results/etc you need to come to a certain conclusion.
They need to keep a record of each step, then start the experiment over and try not to make the mistake again or make changes in what they did to see what outcome they get.
Observation and record keeping are important as you will need to redo an experiment many times to prove that it actually works.
