I may be pushing my luck here, but here it goes.....

I have 3 IF then array statements. They all seem to work, though I don't
understand the output. I am trying to get the average.

1. The first result is an overall average.
2. The second one should be the same but excludes "chevy"
3. The third one should be the same but includes "chevy" only.

I am not sure why the first average is the lowest value. Doesn't make sense.

The formulas (array) a
1.
=AVERAGE(IF('Enroll I'!$H$2:$H$2921=$L$5,IF('Enroll
I'!$H$2:$H$2921<=$N$5,IF('Enroll I'!$L$2:$L$29210,IF('Enroll
I'!$P$2:$P$2921="Treatment",IF('Enroll I'!$M$2:$M$2921="Yes",IF('Enroll
I'!$K$2:$K$29210,'Enroll I'!$L$2:$L$2921)))))))

2.
=AVERAGE(IF('Enroll I'!$C$2:$C$2921<"Chevy",'Enroll
I'!$H$2:$H$2921=$L$5,IF('Enroll I'!$H$2:$H$2921<=$N$5,IF('Enroll

I'!$M$2:$M$2921="Yes",IF('Enroll I'!$K$2:$K$29210,'Enroll
I'!$L$2:$L$2921)))))))

3.
=AVERAGE(IF('Enroll I'!$C$2:$C$2921="Chevy",'Enroll
I'!$H$2:$H$2921=$L$5,IF('Enroll I'!$H$2:$H$2921<=$N$5,IF('Enroll

I'!$M$2:$M$2921="Yes",IF('Enroll I'!$K$2:$K$29210,'Enroll
I'!$L$2:$L$2921)))))))

To make them 1 more similar to #2 and 3., I tried....which doesn't work at
all.

=AVERAGE(IF(OR('Enroll I'!$C$2:$C$2921<"Chevy",'Enroll
I'!$C$2:$C$2921="Chevy"),'Enroll I'!$H$2:$H$2921=$L$5,IF('Enroll

Because I believe formulas #2 and 3 were wrong from the start. You should
start with #1 and recreate #2 and 3. Also note: formula #1 can and should
be simplified to minimize nested formulas, especially if you are using a
pre-2007 version of Excel.

Try the following (NOTE: be sure to copy-and-paste in order to avoid
typos -- except mine :( ):

Formula #1 (intended to be functionally equivalent to what you had):

'Enroll I'!$M$2:$M$2921="Yes",
'Enroll I'!$K$2:$K$29210), 'Enroll

Formula #2 (same as #1 with the additional constraint):

=AVERAGE(IF(AND('Enroll I'!$C$2:$C$2921<"Chevy",
'Enroll I'!$H$2:$H$2921=$L$5,
'Enroll I'!$H$2:$H$2921<=$N$5,

'Enroll I'!$M$2:$M$2921="Yes",
'Enroll I'!$K$2:$K$29210), 'Enroll

Formula #3 (same as #2 with the complementary constraint):

'Enroll I'!$H$2:$H$2921=$L$5,

Does that work for you?

One reason to nest IF() expressions instead of using AND() is if some cells
in, say, L2:L2921 are blank when H2:H2921L5 or H2:H2921N5 is true. In
that case, the condition L2:L29210 would return false positives (TRUE).
Even if that is the case, the original formulas can still benefit from some
simplification.

If you depend on side-effects like that, the following is a safe
alternative. PS: I have assumed all along that you know to enter these as
array formulas; i.e. press ctrl+shift+Enter instead of simply Enter.

Sorry for the incessant repostings, but I just noticed a typo that is sure
to screw you up -- a missing parenthesis in each formula.

Try:


Formula #1 (intended to be functionally equivalent to what you had):

'Enroll I'!$K$2:$K$29210), 'Enroll I'!$L$2:$L$2921))


Formula #2 (same as #1 with the additional constraint):

=AVERAGE(IF(AND('Enroll I'!$C$2:$C$2921<"Chevy",
'Enroll I'!$H$2:$H$2921=$L$5,

Because I believe formulas #2 and 3 were wrong from the start. You
should start with #1 and recreate #2 and 3. Also note: formula #1 can
and should be simplified to minimize nested formulas, especially if you
are using a pre-2007 version of Excel.


I am trying to get the average.
1. The first result is an overall average.
2. The second one should be the same but excludes "chevy"

I may be pushing my luck here, but here it goes.....

I have 3 IF then array statements. They all seem to work, though I
don't
understand the output. I am trying to get the average.

1. The first result is an overall average.
2. The second one should be the same but excludes "chevy"
3. The third one should be the same but includes "chevy" only.

I am not sure why the first average is the lowest value. Doesn't make
sense.

The formulas (array) a
1.
=AVERAGE(IF('Enroll I'!$H$2:$H$2921=$L$5,IF('Enroll
I'!$H$2:$H$2921<=$N$5,IF('Enroll I'!$L$2:$L$29210,IF('Enroll
I'!$P$2:$P$2921="Treatment",IF('Enroll I'!$M$2:$M$2921="Yes",IF('Enroll
I'!$K$2:$K$29210,'Enroll I'!$L$2:$L$2921)))))))

2.
=AVERAGE(IF('Enroll I'!$C$2:$C$2921<"Chevy",'Enroll
I'!$H$2:$H$2921=$L$5,IF('Enroll I'!$H$2:$H$2921<=$N$5,IF('Enroll
I'!$L$2:$L$29210,IF('Enroll I'!$P$2:$P$2921="Treatment",IF('Enroll
I'!$M$2:$M$2921="Yes",IF('Enroll I'!$K$2:$K$29210,'Enroll
I'!$L$2:$L$2921)))))))

3.
=AVERAGE(IF('Enroll I'!$C$2:$C$2921="Chevy",'Enroll
I'!$H$2:$H$2921=$L$5,IF('Enroll I'!$H$2:$H$2921<=$N$5,IF('Enroll

I'!$M$2:$M$2921="Yes",IF('Enroll I'!$K$2:$K$29210,'Enroll
I'!$L$2:$L$2921)))))))

To make them 1 more similar to #2 and 3., I tried....which doesn't
work at
all.

=AVERAGE(IF(OR('Enroll I'!$C$2:$C$2921<"Chevy",'Enroll
I'!$C$2:$C$2921="Chevy"),'Enroll I'!$H$2:$H$2921=$L$5,IF('Enroll

I'!$K$2:$K$29210,'Enroll I'!$L$2:$L$2921)))))))

I will have to use this way as there are blanks. However, when I run this
formula, at least #1, I get the DIV/0 error.

One reason to nest IF() expressions instead of using AND() is if some cells
in, say, L2:L2921 are blank when H2:H2921L5 or H2:H2921N5 is true. In
that case, the condition L2:L29210 would return false positives (TRUE).
Even if that is the case, the original formulas can still benefit from some
simplification.

If you depend on side-effects like that, the following is a safe
alternative. PS: I have assumed all along that you know to enter these as
array formulas; i.e. press ctrl+shift+Enter instead of simply Enter.

which doesn't work at all.

Because I believe formulas #2 and 3 were wrong from the start. You
should start with #1 and recreate #2 and 3. Also note: formula #1 can
and should be simplified to minimize nested formulas, especially if you
are using a pre-2007 version of Excel.


I am trying to get the average.
1. The first result is an overall average.
2. The second one should be the same but excludes "chevy"
3. The third one should be the same but includes "chevy" only.

Try the following (NOTE: be sure to copy-and-paste in order to avoid
typos -- except mine :( ):

Formula #1 (intended to be functionally equivalent to what you had):

=AVERAGE(IF(AND('Enroll I'!$H$2:$H$2921=$L$5,
'Enroll I'!$H$2:$H$2921<=$N$5,
'Enroll I'!$L$2:$L$29210,
'Enroll I'!$P$2:$P$2921="Treatment",
'Enroll I'!$M$2:$M$2921="Yes",
'Enroll I'!$K$2:$K$29210), 'Enroll
I'!$L$2:$L$2921)

Formula #2 (same as #1 with the additional constraint):

=AVERAGE(IF(AND('Enroll I'!$C$2:$C$2921<"Chevy",
'Enroll I'!$H$2:$H$2921=$L$5,
'Enroll I'!$H$2:$H$2921<=$N$5,
'Enroll I'!$L$2:$L$29210,
'Enroll I'!$P$2:$P$2921="Treatment",
'Enroll I'!$M$2:$M$2921="Yes",
'Enroll I'!$K$2:$K$29210), 'Enroll
I'!$L$2:$L$2921)

Formula #3 (same as #2 with the complementary constraint):

=AVERAGE(IF(AND('Enroll I'!$C$2:$C$2921="Chevy",
'Enroll I'!$H$2:$H$2921=$L$5,
'Enroll I'!$H$2:$H$2921<=$N$5,
'Enroll I'!$L$2:$L$29210,
'Enroll I'!$P$2:$P$2921="Treatment",
'Enroll I'!$M$2:$M$2921="Yes",
'Enroll I'!$K$2:$K$29210), 'Enroll
I'!$L$2:$L$2921)

Does that work for you?

I may be pushing my luck here, but here it goes.....

I have 3 IF then array statements. They all seem to work, though I
don't
understand the output. I am trying to get the average.

1. The first result is an overall average.
2. The second one should be the same but excludes "chevy"
3. The third one should be the same but includes "chevy" only.

I am not sure why the first average is the lowest value. Doesn't make
sense.

The formulas (array) a
1.
=AVERAGE(IF('Enroll I'!$H$2:$H$2921=$L$5,IF('Enroll
I'!$H$2:$H$2921<=$N$5,IF('Enroll I'!$L$2:$L$29210,IF('Enroll
I'!$P$2:$P$2921="Treatment",IF('Enroll I'!$M$2:$M$2921="Yes",IF('Enroll
I'!$K$2:$K$29210,'Enroll I'!$L$2:$L$2921)))))))

2.
=AVERAGE(IF('Enroll I'!$C$2:$C$2921<"Chevy",'Enroll
I'!$H$2:$H$2921=$L$5,IF('Enroll I'!$H$2:$H$2921<=$N$5,IF('Enroll
I'!$L$2:$L$29210,IF('Enroll I'!$P$2:$P$2921="Treatment",IF('Enroll
I'!$M$2:$M$2921="Yes",IF('Enroll I'!$K$2:$K$29210,'Enroll
I'!$L$2:$L$2921)))))))

3.
=AVERAGE(IF('Enroll I'!$C$2:$C$2921="Chevy",'Enroll
I'!$H$2:$H$2921=$L$5,IF('Enroll I'!$H$2:$H$2921<=$N$5,IF('Enroll
I'!$L$2:$L$29210,IF('Enroll I'!$P$2:$P$2921="Treatment",IF('Enroll
I'!$M$2:$M$2921="Yes",IF('Enroll I'!$K$2:$K$29210,'Enroll
I'!$L$2:$L$2921)))))))

To make them 1 more similar to #2 and 3., I tried....which doesn't
work at
all.

=AVERAGE(IF(OR('Enroll I'!$C$2:$C$2921<"Chevy",'Enroll
I'!$C$2:$C$2921="Chevy"),'Enroll I'!$H$2:$H$2921=$L$5,IF('Enroll
I'!$H$2:$H$2921<=$N$5,IF('Enroll I'!$L$2:$L$29210,IF('Enroll
I'!$P$2:$P$2921="Treatment",IF('Enroll I'!$M$2:$M$2921="Yes",IF('Enroll
I'!$K$2:$K$29210,'Enroll I'!$L$2:$L$2921)))))))
