I am looking at the relationship between two variables 'x' and 'y'. What analysis do I perform if I had the following question. "At what point in the 'x' variable is there a significant change in the 'y' variable". Say for example, say my 'x' variable ranges from 1 - 10, and I want to be able to say "at point 4, there is a significant change in 'y', compared with points 1 - 3.
What do I look for in my dataset to know if I can answer such a question, and if so, how do I go about analyzing the data to answer such a question?
Thanks in advance.
