How does one average blood pressure readings? Please give an actual
example, such as 152/65.

Put each of the blood pressure readings in their own column:
So A2:A999 would hold the top (systolic) reading and
B2:B999 would hold the bottom (diastolic) reading.
Then you could use:
=average(a2:a999) to get the average sytolic
and
=average(b2:b999) to get the average diastolic
So A2:A999 would hold the top (systolic) reading and
B2:B999 would hold the bottom (diastolic) reading.
Then you could use:
=average(a2:a999) to get the average sytolic
and
=average(b2:b999) to get the average diastolic

To get averages of sistolic(high number) and diastolic(low number) pressures you
would have to have them in separate columns.
You would then take an average of each column.
Sistolic in Column A =AVERAGE(A:A)
Diastolic in Column B =AVERAGE(B:B)

Hi!
Do you mean you want the average of:
152/65
147/72
147/70
If so, split the values into separate cells then it's just a simple
=AVERAGE(.......) formula.
Use Text to Columns to split the values.
Select the range of cells in question, assume A1:A3
Make sure B1:B3 are empty otherwise any data in those cells will be
overwritten.
Goto the menu Data>Text to Columns
Select Delimited
Next
Select Other
In the little box to the right enter a forward slash: /
Click Finish.
Then you can just use the average formula.

Just for the heck of it...........
A1 = 152/65
A2 = 147/72
A3 = 147/70
=ROUND(SUMPRODUCT(--(LEFT(A1:A3,FIND("/",A1:A3)-1)))/ROWS(A1:A3),0)&"/"&ROUND(SUMPRODUCT(--(MID(A1:A3,FIND("/",A1:A3)+1,5)))/ROWS(A1:A3),0)
Returns: 149/69
I don't know anything about blood pressures but you can shorten the formula
if the first value is always 3 digits and the second value is always 2
digits:
=ROUND(SUMPRODUCT(--(LEFT(A1:A3,3)))/ROWS(A1:A3),0)&"/"&ROUND(SUMPRODUCT(--(RIGHT(A1:A3,2)))/ROWS(A1:A3),0)

Many, Many thanks. I got 149/70 but I input A1 as 152/68.
152/68
147/72

Did you work up this formula on your own? Again thanks, Buck Jordan.

I thought about using an array AVERAGE, although I didn't think about using
INT(SUBSTITUTE(A1:A3,"/",".")).
Very clever!

I happen to have workbook for this exact task.Old Red One said:How does one average blood pressure readings? Please give an actual

It's self-contained Excel97 - no macros.
You can enter up to four sets readings (high/low/pulse) across a line and
each line is a day.
The date and times rounded to nearest five minutes are automatically posted.
The min, maxes and averages are all automatically calculated.
I'd be happy to send it to you as an example.

NG.
I was working on the date aspect, for example, and someone else posted a
rounding dates query in Nov, 2005 and Bob Phillips posted a perfect reply
which I was able to adapt for my needs. Also, at that same time, I posted a
request for help resolving a "circular reference..." issue and Peo Sjoblom
provided a pointer to a Tools>Options>Calculation Iteration check box which
was exactly the fix for my situation.
News Groups rule!
My e-mail is pretty much as my header says: salsburyg at comcast dot net.
Substitute the "at" for an at-sign "@" and the "dot" for a dot "." and
remove all spaces of course.
I'd appreciate a critique.
Thx

Hello,
Another one:
=ROUND(AVERAGE(--REPLACE(A1:A3,FIND("/",A1:A3),9,"")),0)&"/"&ROUND(AVERAGE(--REPLACE(A1:A3,1,FIND("/",A1:A3),"")),0)
But this is a little bit slower than Biff's (quickest) and Harlan's
solution.

Bernd
