and the significance depends on 0.05 as u said earlier ryt?

Null hypothesis states that there is no difference between observed result and expected result(for chi-squared) or no difference between your means of two samples(t-test)

So when you have calculated your chi value or t-value.....you look at the table with the correct freedom.
If your calculated value is higher than the value in the table----difference IS significant, null hypothesis is rejected and there is another factor other than chance which is causing this difference.
If your calculated value is lower than the value in the table-----difference is NOT significant, null hypothesis is accepted and the difference is caused by chance.

Hope it helped

ummm..isn't it the opposite of what u said:
If your calculated value is higher than the value in the table----difference NO significant, null hypothesis is accepted
and
If your calculated value is lower than the value in the table-----difference is IS significant, null hypothesis is rejected??
Because if there is Null hypothesis then there is NO significance..

what was the degrees of freedom, how did u calculated dat?

 

[Mukit-ul Islam]

what was the degrees of freedom, how did u calculated dat?

i got 38

 

[confused123]

i got 38

yeah one of my frnd got dat as well. i cudnt figure out what should be the 'n'.
