i feel like im going insane;
i've watched three videos each explaining the p value and when to reject the null hypothesis and each time they've said something different. i thought that if the calculated value was more than 0.05 then the null hypothesis is accepted? is this not correct? can someone explain it all to me as im so confused. what does the 0.05 value even mean

The 0.05 value means that there is a 5% probability that the results are due to chance. The higher the probability that the results are due to chance e.g. 0.07, the less significant the results actually are.
The null hypothesis pretty much says that the results are due to chance.
Therefore, if you produce a value less than 0.05 (5%) then the null hypothesis is rejected because there is a less than 5% probability that the results are due to chance so the results are significant.
If you produce a value more than 0.05 (5%) then the null hypothesis is accepted because there is a more than 5% probability that the results are due to chance so the results arent significant.

I hope this helps your confusion.
