Why do scientists use analysis methods when developing new technology?

They use them when they want to prove something right. They analyze their data and make sure everything is correctly written down and there's no mistakes. Otherwise, the technology they create, will not work and there could be a slight chance that they got one tiny miscalculation and it offsets everything they wanted to be in the technology.

There is no graph to look at on here, but i shall explain them to you. a line graph is just in its title it’s a graph with a line running through the dots to show an increase or decrease. a bar graph is used to show how much or how little something is so a comparison. a scatter plot is used to graph points to tell the data. and i don’t know what a histogram is.
