AI Thread Summary
To find the minimum or maximum acceptable slope from a scatter plot, one must select two points, A(x1,y1) and B(x2,y2), and apply the slope formula m = (y2-y1) / (x2-x1). The choice of points is crucial and should be based on a defined criterion that indicates the acceptable range of slopes for the data. Discussions highlight the need for clarity on what "acceptable" means in this context, as it can vary depending on the application. Additionally, reference to previous sections of related material may provide insights into determining slope uncertainty. Understanding these factors is essential for accurately interpreting the slope in relation to the data presented.

Given a scatter plot graph, how would you find the minimum/maximum acceptable slope?

I know that finding a gradient you would need to choose two points A(x1,y1) and B(x2,y2) and use the formula m = (y2-y1) / (x2-x1).

My question is, which two points to pick out to determine the minimum/maximum acceptable slope of a graph?

Many thanks.

Acceptable to whom? I think you'd need a criterion that could be applied, directing how much latitude you can apply to your line/s of "good fit". How did this question arise, may I ask?

I can't read .doc media. Can you take a screen-shot and post as a gif or jpeg?

Looks like you'll need to turn back to Section 2.2 to find out how they determined their slope uncertainty.
 

Thread 'Need help understanding particle physics and quantum physics'

So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks

Thread 'Raman Spectroscopy help'

I am attempting to use a Raman TruScan with a 785 nm laser to read a material for identification purposes. The material causes too much fluorescence and doesn’t not produce a good signal. However another lab is able to produce a good signal consistently using the same Raman model and sample material. What would be the reason for the different results between instruments?
