Can you provide more details? Are those two n-values for the two dependent variable groups or independent? You should report both the overall and group values! Provide sufficient information so others know what you did and can reproduce your results.
Thanks for that - 2 independent groups.
This is a simple audit cycle - two groups of 30
27 adults in the Audit 1 group and 29 in Audit 2
When I am reporting the Chi-Square result - the adult result will br N=56, and overall results N=60 as katxt has pointed out ?
Is that correct ? It makes perfect sense
I am, as you no doubt have picked up, very new to biostats
I'm not entirely sure what is going on but this is what I have pieced together. Let me know if I have misinterpreted.
You are looking at two separate tests, Adults and Totals. (We will ignore the fact that these two tests use much the same data and so are not independent)
Let's look at the Totals first. We have two audits of 30 total each, a grand total of 60.
14 and 22 adhere, a total of 36.
If there was no difference you would expect 30/60x36 = 18 in each group.
Is a 14 22 split significantly different from a 18 18 split? This is your chi square test. X2 turns out to be 1.78 with a p value of 0.18, so X2(1, N=36) = 1.78, p = 0.18 not sig.
For the adults, 27 and 29 per group 56 total
32 adults adhered so expect 27/56x32 and 29/56x32 = 15.4 and 16.6 for the audits
We actually see 11 and 21. Is this significantly different from 15.4 and 16.6? Chi square test.
This one turns out X2(1, N=32) = 2.45, p = 0.12 not sig.
