• How to calculate the average of the 1 d array?

  Could someone please help me, how can I calculate average of the 1 d array? For example, if the table 1 d - is [2, 3], I would get average = 2.5. Thank you very much!

  Use the average function. You can use the search or the quick menu to look for where you don't know where to find.

• How to calculate an average for each quarter in a year

  Hello world
  
  
  I have a table that stores all the unit tests for the data. I'm figuring avg unit tests that have been recorded by quarter in one year
  
  I tried with avg and the meter, but I'm sure that the results returned are not perfect
  
  Help me in this scenario.
  
  Thank you
  Sriks

  so if there are 10 unit tests then the avg is 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10/10

  It is a weird way to definig average. Anyway, why:

  2005-2 Q 5 2.5

  According to your package:

  (1 + 2 + 3 + 4 + 5) / 5 = 3

  not 2.5. I'll assume that it's a typo. Now based on Mathematics:

  1 + 2 + 3 +... + n = (1 + n) * n / 2

  The foregoing your 'average' would be:

  (Count + 1 / 2)

  Also, I suspect tc_vts column data type is DATE, if so:

  select  to_char(tc_vts,'YYYY-Q"Q"') "year-Quarter",
          count(*) "Total cases",
          (1 + count(*)) / 2 "Average of total cases"
    from  Testcycl
    group by to_char(tc_vts,'YYYY-Q"Q"')
    order by "year-Quarter"
  /

• Calculate the average per slot?

  Hi Chaps,

  I am a beginner on numbers (almost everything on Mac I would say) and I need help to calculate average values.

  These are calculated values (column 2) taken on a specific time of the day (column 1).
  I managed to create a third using a built-in function to get the time slot (column 3).

  14:58:42	235	14
  14:59:42	274	14
  15:00:50	7937	15
  15:01:55	5157	15
  16:02:57	1822	16
  16:03:57	207	16

  Can please somebody see me step by step how to calculate the average by time slot as below?

  14	254,5
  15	6547
  16	1014,5

  Kind regards

  Assuming you data in a table named 'Data' and the information is summarised in another table (right) named "Summary".

  Select cell B1 in the summary table and then type (or copy and paste from here):

  = SUMIF(Data::C,a1,Data::B) ÷COUNTIF (Data::C, a1)

  shortcut for this is:

  B1 = SUMIF(Data::C,a1,Data::B) ÷COUNTIF (Data::C, a1)

  Select cell B1, copy

  Select column B, paste

• Calculate the average of a report by column

  Hello ~
  I have several reports in several areas on a page. I have columns for the time, count, Total and average. I'm trying to understand how to calculate the average for the data that is displayed. For example:
  
  By time
  
  Time count Total average
  2 2 4
  5-2-10
  10-3-30
  
  -----
  17 7 44 6.2857
  
  
  What is happening now is that the app is on average each line first and then adding the middle column. Is there anyway to average the totals and not the lines?

• How to calculate the signal / noise from the graph?

  In my current project, I read a periphera voltage signal. the signal lead noise even after filtering.  So, to identify the necessary data, I averaged the signal.

  I have attached the file with an image of graphics. In this graph, the recorded data are drawn black and medium online graph is plotted in red. Now, I have to calculate the ratio of signal to noise to specify with these peak values. How to do?

  As the signal passes through zero, be careful in the way you set the signal / noise.  For sinusoidal signals, that ratio is defined as the RMS value of the noise (the signal with the desired sinusoidal signal deleted) divided by the effective value of sinusoidal component.

  First of all I would like to subtract the average value of the raw signal.  The difference is the noise.  You can set the signal / noise.  A RMS calculation might work.  If you have a mathematical model for the desired signal, a fitting for this model can be useful too.

• Calculate the average value

  the data that I measured changed quickly, so I want to get the average value of the data

  Don't tell me to use mean.vi, I already know.

  and I got an idea that is to add data in a table every time, then the sum of all value data and take the line of result by the number of items

  but I don't know how to do this, anyone can build a simple vi to show me? Thank you

  I enclose my vi that uses mean.vi to the average value of calc, you can remove it and help in your path, thank you!

  Do not add your data in a table that grows forever. What a waste of RAM. To calculate the average, you only need to sum and N.

  Here is a simple code to accumulate the sum of the values in a shift register and divide by the number of add operations.

  

• Filtering and calculate the averages for subsets of a table

  I have a 2D picture that comes out of a loop, and I need to calculate the average of the subsets corresponding to iterations 0-9, 10-19, etc...  In addition, I need to filter the values above and below acceptable limits before calculating the average.  Any suggestions for how to address the issue?

  Here are examples of code does exactly that. This post, looks like you need an upper limit as well. I'll leave that as an exercise for you.

• How to calculate the CPU Ready on Cluster DRS via Powercli?

  Hi all!

  I have a DRS Vsphere cluster. I want to know what is the value of the loan of CPU I have in my group.

  For example, I get 20% of powercli value, it is normal for the cluster, but if I have 100% or more, I have a problem.

  How to achieve via Powercli? And how to calculate the percentage values correctly?

  I know, I can get all values of CPU Ready of VMs cluster, but IT is not the same thing, I need overall value of CPU Ready.

  Thanks in advance!

  As far as I know you can get the cpu.ready.summation for ESXi nodes or VMs.

  For a cluster, you will need to get the value of each node in the cluster ESXi and then take the average.

  The metric cpu.radey.summation is expressed in milliseconds.

  To get a percentage, you need to calculate the percentage of loan period during the interval during which it was measured.

  Something like this (this will give the loan current %)

  $clusterName = "mycluster.

  $stat = "cpu.ready.summation".

  $esx = get-Cluster-name $clusterName | Get-VMHost

  $stats = get-Stat-entity $esx - Stat $stat - Realtime - MaxSamples 1 - forum «»

  $readyAvg = $stats | Measure-object-property - average value. Select - ExpandProperty average

  $readyPerc = $readyAvg / ($stats [0].) IntervalSecs * 1000)

  Write-Output "Cluster $($clusterName) - CPU % loan $(' {0:p}'-f $readyPerc).

• How to calculate the 99th percentile of a stream of number...

  Environment:
  
  Oracle 11.2.0.3 EE on Solaris 10.5
  
  I have a stream of numbers (for example 1000), I need to calculate the 99th percentile of the distribution of this stream in such a way that when a new ' number is introduced, I can tell if the new number is above the 99th percentile of the distribution of my workflow.
  
  I don't have a good idea of the nature of the distribution if it's important.
  
  I am NOT, I repeat NOT a statistician! :-)
  
  I read the docs on the different functions available, ntile, percent_rank, percentile_cont, percentile_disc, etc. I also read a lot of articles referenced via Google.
  
  The examples are not exactly what I'm trying and I was unable to get the result I need by trial and error (mostly!).
  
  All suggestions are welcome!
  
  If you need additional information, I will try to provide what I know.

  Hi Frank

  Well to try to facilitate the description of periods, I managed to confuse the issue a little more.

  Sorry about that.

  I need to use days not months. The script will be executed every day and watch period of ago 210 days to 31 days following there from 30 days at present.

  With respect to the expected result, I need somehow calculate what turnover represents the 99th percentile (or 90th everything that works in the example) and store that in my table of this customer.

  Then after a CREATE TABLE statement for this table and you want that it contains, given the data published in the sales table, after it is filled.

  Another process on the whole will consider the last average of 30 days and determine if this average exceeds sales 99th percentile figure and initiate an action (alert email, etc.) if it is.

  My problem is that I don't know how to calculate this 99th percentile number.

  After the sample data, I'm guessing it should be close to the number of SD 3, but after reading your comments, maybe that's not correct.

  That's my guess. Sometimes deviations corresponding to percentiles, sometimes they did not. People choose one or the other, depending on what amounts to their data, and what they want to show on these data. Your client has apparently chosen percentile. Unfortunately, we do not seem to know something about the problem.
  Before you can solve this problem for your customer, you must understand what the problem is. Talk to your client and know exactly what is wanted here.

  Here is one possible approach.

  WITH     got_month_avg     AS
  (
       SELECT       custno
       ,       AVG (amount)     AS month_avg
       FROM       sales
       WHERE       tran_dt     >  SYSDATE - 30
       AND       tran_dt     <= SYSDATE
       GROUP BY  custno
  )
  ,     got_threshold_amount     AS
  (
       SELECT DISTINCT
            custno
       ,     PERCENTILE_CONT (.4)          -- or .99
                WITHIN GROUP (ORDER BY  amount)
                          OVER ( PARTITION BY  custno )          AS threshold_amount
       FROM    sales
       WHERE     tran_dt     >  SYSDATE - 210
       AND     tran_dt <= SYSDATE -  30
  )
  SELECT       a.custno
  ,       a.month_avg
  ,       t.threshold_amount
  FROM       got_month_avg          a
  JOIN       got_threshold_amount  t  ON  t.custno  = a.custno
  --WHERE       a.month_avg     >= threshold_amount
  ORDER BY  custno
  ;
  

  Output:

  `   CUSTNO  MONTH_AVG THRESHOLD_AMOUNT
  ---------- ---------- ----------------
           5      126.5           4812.6
          26 4602.44444           3102.2
  

  I set the WHERE clause comment, just so that we could see the results of each custno. I also put the extremely low threshold (40th percentile) just for a custono would be selected if you are not using the WHERE clause.

  Subqueries are average in the last 30 days and the 40th percentile for 180 days before that. Let's take a look at custno = 5. There were two rows in the last 30 days (225 and 28 amounts), then the average in the last month is (225 + 28) / 2 = 253 / 2 = 126,5.
  Within 180 days prior to that, he had 7 amounts, in ascending order:
  1st (0th percentile): 647
  2nd (17th percentile): 1869
  3rd (33rd percentile): 3065
  4th (50th percentile): 7434
  5th (67th percentile): 8435
  6th (83rd percentile): 9393
  7th (100th percentile): 9712
  Since (for now), we are interested in the 40th percentile. It will be more than number 3065 (33rd percentile) and less than 7434 (50th percentile), 3065 to 7434, somewhat 40% being somewhat closer than 33% to 50%. This number turns out to be 4812.6.

  Try this - http://www.pythian.com/news/29703/oracle-instance-memory-usage/ for each of your instances.

  As far as I know, different instances may share only the binary code oracle and using libraries, so you should be able to easily understand the amount of memory of all instances of 12.

• PDF form field calculates the AVERAGE incorrectly

  I have a PDF form field which is defined to calculate the AVERAGE of the other 4 fields. Each of these other areas has its validation configured to allow only the values from 1 to 3.
  
  The average field is dividing the total by 4, even if a person completes only 2 fields. I thought THAT AVERAGE would count only the fields that have a value in them. But it is to see which ones are empty as containing a 0, even if it is an invalid value for this field.
  
  How can I fix? The client really wants to have up to 4 fields and an average of only those that are filled. I thought it was what average was supposed to do.
  
  Is there a way to tell Acrobat to ignore fields if their value is less than 1?

  and another table
  
  BRANDS (id, schoolboy_id, discipline_id, mark, mark_type). a schoolboy
  
  on a discipline (math, for example), a schoolboy may have more points. I want to calculate the average mark, but for every schoolchild. then, for example I want to generate a report that contains the first name, the family name of the schoolboy and nearby, the average of the marks.
  How can I calculate the average of all brands for every schoolchild ?
  
  Thank you!

  Maybe something like:

   SELECT   first_name, last_name, b1.avg_mark
     FROM   schoolboys a1, (  SELECT   schoolboy_id, AVG (mark) avg_mark
                                FROM   marks
                                WHERE   discipline_id = 4 -- specify whatever discipline_id you want
                            GROUP BY   schoolboy_id) b1
    WHERE   a1.id = b1.schoolboy_id
