Question

what if significance value is greater than 0.05

Answer 1

A p-value above 0.05 doesn't necessarily say 'your correlation is meaningless'.

However, there's more than a 5% chance that you could see a sample correlation at least as far from zero when the population correlation is zero.

Loosely this means you can't confidently distinguish the population correlation your sample was drawn from, from one that is zero (assuming you do mean to set your significance level to 5%)

Answer 2

In the majority of analysis,an alpha of
0.05 is used as the cut off for significance.If the p - value is less than
0.05,we reject the null hypothesis
that there's no difference between the
means and conclude that a significant
difference does exist.
