Hey guys
So I've been doing some medical research and I have a great result by no idea how to approach working out the P value.
Basically with a new technique we can reduce the number of subsequent (revisional) operation a patient needs. The data is as follow:
Old method
1 operation - 14
2 operations - 25
3 operations - 16
4 operations -5
New method
1 operation - 35
2 operations - 18
3 operations - 5
4 operations - 2
So we're really pleased that using the new method patients are needing less operations. I'm trying to write this up and get some sexy statistics with p values, CI and all that but I've been trying to teach myself how to do it for god knows how long and I'm real stumped...
Is there anyone that can help me and explain how to do this? (in non-statistician language :roll eyes
Thanks!!!
