0.01 or 0.001 level of significance?

[Sukhmani Singh]

Respected Sir and group members,

Greetings of the day!

I have a small query. If my statistical analysis result (for e.g., One-way ANOVA) comes out to be significant as p-value is 0.000.  So, we write it as F(df)= Value of F, p<.001.

But while writing the interpretation, Should we write it as…. “The result is significant at 0.01 level of significance OR significant at 0.001 level of significance.” 

I am asking because generally we compare the p-value with either 0.05 or 0.01 level of significance, and write that result is significant at 0.05 or 0.01 level of significance. But what if, p-value is 0.000 …then what level of significance should we specify – 0.01 or 0.001?

Means, Can we write – Significant at 0.001 level of significance?

Kindly guide.

Regards,

Sukhmani.

P- value 

Level of significant 

These are two think p value interpretation start with < .05 I.e p value is significant or > .05 not significant at 95 % or 99 % level of significant..

Thankyou Manoj sir for your valuable input.

I guess, we say it like this - 0.01 or 0.05 level of significance OR 99% or 95% level of confidence. May be Neeraj sir can guide us on this.

My query is that - Can we write - "The result is significant at 0.001 level of significance?"

Regards.

Hi Sukhmani,
Ideally, p-values are chosen beforehand depending upon how sure you want to be before rejecting a claim (null). It is not always 1/5 or 10 %, it is subjective and domain-specific or even sometimes problem-specific. [Read more about the trade-off between type I error & type 2 error. I find it very similar to sensitivity & specificity in a classifier, both discusses confusion matrix]
Usually, scholars go with a 5 % level of significance, you should report your results based on your chosen p-value no matter what results you are getting from your analysis.

I think level of significance should be defined by user. generally for social studies we take it as 0.05. if your p value is 0.000 then it very very less than your defined tolerance level. ie. prob that your hypo. is true is very very small. or you can say your calculated value falls within the highly rejected region.

[Shuvendu Chakraborty]

you can say result is highly sqtatistically significant. but what hypothesis you have taken that is also important to write the conclusion.

You can nt do for .001
