如何在 excel 表中使用 IF 编写多个条件？

Question

I am trying to test whether the subject ID tested in an application is classified (ADHD-combined, ADHD-inattentive or healthy) correctly or not. I have a table with identifier names and the decision in percentages.

A	B
subject_id	decision
NDARAA112DMH	0.55196626
NDARAD615WLJ	0.58124495
NDARAG143ARJ	0.65364915

I want to have a table like this after I use the "IF" formula in excel.

A	B	C
subject_id	decision	result
NDARAA112DMH	0.55196626	combined
NDARAD615WLJ	0.58124495	inattentive
NDARAG143ARJ	0.65364915	inattentive

How to write this expression in an excel formula if B2 = 0.55±0.02 then write "combined" if B2 = 0.59 ± 0.09 then write "inattentive" else write "healthy". Any help would be highly appreciated.

Answer 1

=IF(ABS(B2-0.55)<0.02,"combined",IF(ABS(B2-0.59)<0.09,"inattentive","healthy"))
