Hi, could you guys help me understand statistics. Basically Ive recorded some data from an experiment I carried out. Using programs like excel and minitab I have plotted scatter graphs, regression curves etc.
Some of my questions:
1. What does finding the equation of say a curve or line do i.e. the purpose?
2. If I find the P value of one of my graphs what do I do with this value.
3. What stats can I apply to my data to asses whether it is reliable or not, or whether the data is significant or not?
Essentially I need methods to let me know whether I can reject or accept my hypothesis, I'd like to know if the data I collected happened by chance or is statistically significant.
