Frequency * Time histogram data

[Measels]

Hi,

I have searched far and wide for a solution to this and spent hours trying to figure it out, and I am now admiting defeat and hoping someone will be able to help me.

I have the following type of data:

Example dataset:

	A	B	C	D	E
1	Level	Time	Bin Range	Level Frequency	Level Frequency * Time
2	1.2	40	0	2
3	3.5	100	1	0
4	3.9	30	2	0
5	2.8	130	3	3
6	1.6	50	4	1
7	6.2	80	5	0
8	3.4	10	6	1
9	4.7	240	7	0

</tbody>

The real data is more substantial (over 10,000 cells worth), this is just to illustrate.

I have generated the frequencies using the following formula "=COUNTIF(A:A,"<"&C3)-COUNTIF(A:A,"<"&C2)". This has worked fine and I can generate a histogram from this.

The problem is that in addition to this, I would like to look not just at the frequency of the level appearing, but to generate a histogram of time spent at that level. I.E. I am trying to come up with a formula that looks at the column with the levels (column A) if the value in column A falls in the correct range, then the corresponding value in column B would be recorded and summed.

Not sure if I explained that too well. For this small data set, I can of course fill in the values manually, and they would come out as shown below:


Example manually calculated solution:

	A	B	C	D	E
1	Level	Time	Bin Range	Level Frequency	Level Frequency * Time
2	1.2	40	0	2	90
3	3.5	100	1	0	40
4	3.9	30	2	0	0
5	2.8	130	3	3	140
6	1.6	50	4	1	240
7	6.2	80	5	0	0
8	3.4	10	6	1	80
9	4.7	240	7	0	0

Thank you in advance for any suggestions to do this! It's driving me crazy!

A SumIfs works in this case.

=SUMIFS(B:B,A:A,">" & C2,A:A,"<" & C3)

Thank you so much, that worked brilliantly, and so much more simple than the various things I was trying.

Thanks again!
