I have a table in excel setup as followed:
DATE | TIME | PERSON IDENTIFIER | ARRIVAL OR LEAVING
01/01/15 | 13:00 | AB1234 | A
01/01/15 | 13:01 | AC1234 | A
01/01/15 | 13:03 | AD1234 | A
01/01/15 | 13:05 | AE1234 | A
01/01/15 | 13:09 | AF1234 | A
01/01/15 | 13:10 | AB1234 | L
01/01/15 | 13:15 | AG1234 | A
01/01/15 | 13:13 | AC1234 | L
The table shows when people arrive and leave a medical ward. The ward holds 36 patients and I'm wanting to get an idea of how close it is to capacity (it's normally always full). The ward is open 24/7 and has patients arriving 24/7 but I'd like to show the time it is at the certain capacities.
For example if we inputted 24 hours of data
36 patients (0 empty beds) - 22hr 15min
35 patients (1 empty bed) - 01hr 30min
34 patients (2 empty beds) - 00hr 15min
I'm thinking we just need a count for every time some arrives and a negative count when they leave but I can't figure out how to extract the time from that.
This is going to be pretty ugly (NB using your columns from above):
order the entries sequentially
you can keep a running tally in column E of patients on hand currently with E1 = 36(or whatever starting value you have) and =IF(D2="A",E1+1,E1-1).
Get the time elapsed since the previous entry with =(B3-B2) and put that in column F
Count the chunks where you had less than a full house with =SUMIF(F:F, "<36")

I have two columns in my excel,Session_Start_time and Time_taken. Session_start_time has date and time and time_taken has time taken to complete the session like below .
For example
Session_Start_time | Time_Taken
01-AUG-2016 00:03:57 | 10
01-AUG-2016 00:07:19 | 15
01-AUG-2016 00:10:28 | 10
02-AUG-2016 00:13:26 | 20
02-AUG-2016 00:20:26 | 30
02-AUG-2016 00:25:26 | 20
03-AUG-2016 03:20:26 | 30
03-AUG-2016 04:13:26 | 40
03-AUG-2016 07:13:26 | 40
I need to group the session_start_time by the dates and have the avg time_taken for that particular day.
Session_Start_time | Time_Taken
01-AUG-2016 | 11.67
02-AUG-2016 | 23.33
03-AUG-2016 | 36.66
You could add a third column that pulls out just the date of Session_Start_Time with the formula below starting in C2 and drag it down to fill:
=MONTH(A2)&"/"&DAY(A2)&"/"&YEAR(A2)
From there, you could create a pivot table with your new column as your row labels, and your Time_Taken as y our values.
In my theoretical data set, I have a list which shows the date-time of a sale, and the employee who completed the transaction.
I know how to do grouping in order to show how many sales each employee has per day, but I'm wondering if there's a way to count how many grouped days have more than 0 sales.
For example, here's the original data set:
Employee | Order Time
A | 8/12 8:00
B | 8/12 9:00
A | 8/12 10:00
A | 8/12 14:00
B | 8/13 10:00
B | 8/13 11:00
A | 8/13 15:00
A | 8/14 12:00
Here's the pivot table that I have created:
Employee | 8/12 | 8/13 | 8/14
A | 3 | 1 | 1
B | 1 | 2 | 0
And here's what I want to know:
Employee | Working Days
A | 3
B | 2
Split your Order Time column (assumed to be B) into two, say with Text to Columns and Space as the delimiter (might need a little adjustment). Then pivot (using the Data Model) as shown:
and sum the results (outside the PT) such as with:
=SUM(F3:H3)
copied down to suit.
Columns F:G may then be hidden.
I fully support #Andrea's Comment (a correction) on the above:
I think this could have been made simpler. If you remove the "Time" in values of the pivot table and then move "Order" from columns to values and use distinct count as in the example. It should count Employee per date making the sum not needed. If you scale this to make it larger. Say 50 dates then the =Sum() needs to be moved each time.
after years of quietly learning from this site I've finally hit a question who's answer I cannot seem to find on StackOverflow...
I have a pivot table that needs to calculate Net Promoter Score from several groups within a population.
Net promoter score is calculated like so:
[% of Population that give 9 or 10/10] - [% of Population that give 1 to 6/10]
Each individual record in my source data can only have a single Score of between 1 and 10:
RAW DATA:
Date (dd/mm) Country Type Score (1-10) NPS Category
01/05 US Order enq. 9 Promoter
13/05 US Check-out 5 Detractor
28/05 US Order enq. 7 Passive
So, with help from the answers below I've added a column to categorise each individual into the Promoter (9 or 10), Passive (7 or 8) and Detractor (1 to 6) groups based on that score: screenshot of raw data (with sensitive items hidden).
All that remains now is:
How can I create a calculated 'NPS' column like the one shown in my (rudimentary) representation of a pivot table below that takes the Detractor value from the Promoter value?
D = Detractor group
Pa = Passive group
Pr = Promoter group
| Order enquiry | Check-out |
| D Pa Pr NPS | D Pa Pr NPS |
-------------------------------------------------- |
GB | | |
May | 0 0 100 100 | 30 20 50 20 |
Jun | 10 30 60 50 | 35 35 60 25 |
Jul | 30 20 50 20 | 40 10 40 0 |
US | | |
May | 45 15 40 - 5 | 50 10 40 -10 |
Jun | 40 30 30 -10 | 40 30 30 -10 |
Jul | 5 35 60 55 | 20 40 40 20 |
My attempt at a calculated column can be seen in this screenshot. This results in an error and of course I haven't managed to convert the NPS counts into percentages yet.
It would be my suggestion to create a new column in the source that calculates D, Pa,Pr by a formula.
You can now create the % for these values in the pivot. The NPS column can either be calculated after pivoting the output field, or by creating a pivot-column formula in Excel.
It's not clear from your question how your data is laid out, or what exactly you're asking. From what I can see, you need to add a column in your raw data table, which says something like
=COUNTIFS(UniqueID,MyUniqueID,Score,">=9")-COUNTIFS(UniqueID,MyUniqueID,Score,"<=6")
Then another column that says
=IF(NetPromoter>=9,"Pr",IF(NetPromoter>=7,"Pa","D"))
And then in your pivot table you add the Classification as a new subcolumn, and add the NPS as the Average of your NPS column, or something like that.
Please show your data if you want the formulas changed to meet your actual range/variable terms.
I have a table of data that has a format similar to the following:
EventID | Event Date
--------------------
1 | 1/1/2014
2 | 2/8/2014
3 | 10/1/2014
4 | 2/5/2014
5 | 4/1/2014
6 | 9/1/2014
What I am trying to do is create a DAX formula to rank each event in the order that it happened for the year. So I want to end up with something like this. This way I can compare the events year over year as the events don't happen on any regular time schedule.
Event Date | Year | Rank
------------------------
1/1/2014 | 2014 | 1
2/8/2014 | 2014 | 2
10/1/2014 | 2014 | 3
2/5/2015 | 2015 | 1
4/1/2015 | 2015 | 2
9/1/2015 | 2015 | 3
I have tried to do this by creating a formula that will give me the day number of the year:
Day of Year =(YEARFRAC(CONCATENATE("Jan 1 ", YEAR([Event Date])),[Event Date])*360)+1
Then using rankX on this table, but I cant seem to get the proper result. Perhaps I am not understanding the use of rankX or going about this the right way.
=RANKX(FILTER(Event,EARLIER(Event[Event Year])=Event[Event Year]),Event[Day of Year])
or
=RANKX(All(Event[Event Year]),[Day of Year],,1,Dense)
Any ideas would be much appreciated!
Thanks for any help in advance!
Create the following measures:
[Year]:=YEAR(LASTDATE(Event[Event Date]))
and
[Rank]:=RANKX(FILTER(ALL(Event),[Year]=YEAR(MAX(Event[Event Date]))),FIRSTDATE(Event[Event Date]),,1,DENSE)
and this is the result that you get:
Note: My dates are in UK format and I suspect yours were in US format, so the rankings do not appear to tally with your example, but it does work!
My set up is fairly simple. I have paired data where one column is time and the next is a value corresponding to that time point. This recurs for many trials with each trial having a different number of time points
Time Freq
0.216 0.000
0.423 4.835
0.620 5.067
0.784 6.108
0.971 5.355
1.156 5.395
1.311 6.470
1.433 8.170
1.575 7.034
1.752 5.673
1.925 5.758
2.077 6.602
2.180 9.675
2.363 5.477
2.487 8.022
2.616 7.795
2.773 6.344
2.915 7.050
3.074 6.283
3.208 7.495
3.395 5.344
3.535 7.111
3.682 6.839
3.830 6.730
4.023 5.185
This is an example from a table. What I want to do is to create a formulate that will pull the Max Frequency when Time is greater that 1 and less than 3. I know this can be done by manually selecting the range, but I have many different ranges that I want to find the max freq for would like to be able to just input the column.
You can reference upper and lower bounds for the time variable like this:
+---+----+----+-------+
| | D | E | F |
+---+----+----+-------+
| 1 | LB | UB |MaxFreq|
| 2 | 1 | 3 | 9.675 |
| 3 | 0 | 1 | 6.108 |
| 4 | 1 | 2 | 8.17 |
| 5 | 2 | 3 | 9.675 |
+---+----+----+-------+
F2: =MAX(IF(($A$1:$A$26>$D2)*($A$1:$A$26<$E2),$B$1:$B$26))
F2 is an array formula--confirm the entry with the combination Ctrl+Shift+Enter (not just Enter). It can be copied down as far as needed.
