I have been given a methylation data set with a range of beta and M values and . I am very new to this and I am wondering what the best way would be to analyse both the Beta values between two groups of people (disease/control). What would be the best way to present this data (Bar graph/scatter plot?)
Also if possible, could someone explain why you would need to look at the variance or do an F-test?
I am brand new to this.
