1

I have data which looks like this

          Reason 1    Reason 2     Reason 3
  ----------------------------------------------
 Year 1 |     20    |    120    |    120    |
 Year 2 |     220   |    20     |    2120   |
 Year 3 |   2053    |    1120   |    1200   |
 Year 4 |     30    |    3120   |     12    |

I now want to know if there is any kind of correlation between Reason 1 and the other two reasons. The idea is if I tackle reason 1, is there any way of telling it might also affect reason 2 and reason 3 ? Which test should I use to check this? The numbers indicate the frequency of occurrence.
