This method is indispensable for the statistical analysis of experimental data, drawing calibration curves in analytical chemistry, etc.
Robert Boyle
Analytical chemistry use the general language of chemistry.
Anyone can use alchemy as it is not that different from chemistry. But like chemistry it has hazards so you should use caution, acquire knowledge, have emergency numbers for things such as poison control, and safety equipment. It can be performed with many instruments used in chemistry.

Green chemistry focuses on eliminating the use of toxic chemicals in chemistry without stifling.
A teacher teaches it to kids.
If most of them lie below the line, then that line isn't the best fit. The exact layout depends on what definition you use for "best fit", but any definition will produce a line that has roughly the same number of data points on each side of it.
By finding the line of best fit and using the straight line equation formula.
Linear Regression is a method to generate a "Line of Best fit" yes you can use it, but it depends on the data as to accuracy, standard deviation, etc. there are other types of regression like polynomial regression.

You should use a curve if the scatter plot shows a clear curving shape. Otherwise draw a straight line. But a line of best fit should never zigzag from point to point.
Chemistry can be learned online by the use of the Chemistry Online catalog which is a collection of all things that have relevance to Chemistry and its basic principles.
Start by putting your ruler following the graphs trend (neg/pos) then either draw the line through as many points as possible or ,preferably with an equal no. Of points on each side of the line
to gather the average of the results, it's also to see if the academic side of your investigation is right. best fitted lines our also used in chemie, and matte.
yes
If plotting a graph and are producing a straight line to find a gradient: You plot a line of best fit, then you plot two other lines starting from the same point which show the extreme lines of best fit (do this in fainter lines so that the best one stands out). Find the gradients for all three lines, use the first line that you drew as the main value. Then find the largest difference between the middle line and the extreme lines E.g. if the gradient of the lines were: First line gradient = 1.2 Second (Top extreme line of best fit) gradient =1.5 Third (Minimum extreme line of best fit) gradient = 1.0 Find the larget difference: 1.5-1.2=0.3 1.0-1.2=-0.2 Therefore the largest difference is 0.3 (not 0.2) Therefore your final result would be: 1.2 (+-) 0.3 I hope this helps :D
it is the best
