is p=0.05 significant?

Question

If I obtain a p value of exactly 0.05, is that generally considered to be significant? Or does it have to be less than 0.05? My accepted p value is p < 0.05 but someone told me that p=0.05 is also significant.

Answer 1

I'd always assumed that it was just values less than 0.05, so your p-value of 0.05 would not be significant.
Generally, when you have the tests, your null hypothesis is that it's equal to, and the alternative is that it's greater than / less than / not equal to, so there would be no equal sign for the significance.

If it's for a class, you might have to ask your teacher to be positive, though.

Answer 2

P Value Less Than 0.05

Answer 3

That depends on what p is. Without knowing what p represents, there's no real way to know what values are significant. If you have an inequality with a hard < or > sign, then your answer of p < 0.05 is probably correct as stated. If the inequality actually has a <= or >= sign, then your answer should probably be p <= 0.05.

In another sense, "significant" usually refers to significant figures; the number 0.05 has one significant figure.

Answer 5

Because the calculated P is continuous, P = 0.05000000+ can never happen. It depends on how many decimal places you carry it out to. Don't worry about it.
