# Which test should I perform?

I have 2 datasets. Dataset X looks like this:

Jmp_o   Nws_r
1       0
0       1
1       1
0       1
0       1
1       0
1       0
...    ...


I calculate the conditional probability P(jmp_o=1|nws_r=1). There is another dataset Y which is like:

Jmp_o   Nws_r
1       0
0       0
1       0
0       0
0       0
1       0
1       0
...    ...


From dataset Y I calculate unconditional probability P(jmp_o=1).

I want to test whether these 2 probabilities are statistically different (by means of p-value).

What test should I perform?

Further clarification: first I have dataset X from where I calculate the conditional probability. Then from dataset X I create a subsample which has Nws_r=0. After creating dataset Y, I calculate the unconditional probability. Now I need to check whether they are different.

• I don't know why the datasets look like that! I'm posting an excel sheet. – Deepan Das Sep 6 at 9:26
