Count and Percentage

The following image shows the number and percentage of contacts that the contact center handled during four weeks:

count-and-percentage

Week of contactWeek of contact is the aggregation field. It represents the week number when the contact occurred. Values in the other columns are aggregated by the week of contact.
# ContactsNumber of contacts that the contact center handled in each week.
# SuccessOf the handled contacts, this represents the number of contacts that the contact center classified as successful.
% ContactsPercentage of contacts that the contact center handled each week.
% SuccessOf the handled contacts, this represents the percentage of contacts that the contact center classified as success each week.
% Weekly SuccessThis is a calculated metric and, of the number of contacts handled each week, it represents the percentage of contacts that the contact center classified as success in each week.

% Percentage

Contact Center and Engagement Studio calculates the percentage as follows:

    Number of occurrences of a subject
% = ---------------------------------- * 100 
       Total number of occurrences

The following table shows how the Contact Center and Analytics Studio calulates % Contacts and % Success are columns:

% Contacts% Success% Weekly Success
(Number of weekly contacts/Total number of contacts) * 100(Number of weekly contacts classified as success/Total number of contacts classified as success) * 100(Number of weekly contacts classified as success/Number of weekly contacts) * 100
(26/366) * 100 = 7.10 %(26/366) * 100 = 7.10 %(26/26) * 100 = 100%
(114/366) * 100 = 31.15 %(111/366) * 100 = 30.33 %(111/114) * 100 = 97.37%
(122/366) * 100 = 33.33 %(110/366) * 100 = 30.05 %(110/122) * 100 = 90.16%
(104/366) * 100 = 28.42 %(95/366) * 100 = 27.05 %(95/104) * 100 = 91.35%

Daily Average

The following image shows the number of contacts that the contact center handled by day:

average-daily

Day of contact (DD)Day of contact is the aggregation field. It represents the day of the the month when the contact occurred. For example, the images shows that the contact center handled contacts in day and 3, but there weren't handled contacts in day 2.
# ContactsNumber of contacts that the contact center handled in each week.
DAvg ContactsDaily average. Average number of contacts per day.

Contact Center and Engagement Studio calculates the daily average as follows:

       Number of occurrences of a subject
DAvg = ----------------------------------
              Last day - First day

The following table shows the Contact Center and Analytics Studio calculates DAvg Contacts column:

Sum

Contact Center and Engagement Studio calculates the sum as follows:

∑ = Durarion1 + Durarion2 + ... + DurarionN

In the second image, the Contact Center and Analytics Studio calculates the sum of the durations of the contacts as follows:

∑ = 00:42:48 + 01:55:56 = 02:38:44

Average

Contact Center and Engagement Studio calculates the average as follows:

    Durarion1 + Durarion2 + ... + DurarionN
∑ = ---------------------------------------
                        N

In the previous equation, N is the number of records.

The following table shows the Contact Center and Analytics Studio calculates µ Duration column:

Minimum

The minimum duration in day 15 is 00:00:00 and in day 17 is 00:04:12.

The global minimum duration is 00:00:00.

Maximum

The maximum duration in day 15 is 00:17:33 and in day 17 is 00:16:46.

The global maximum duration is 00:17:33.

95th percentile

The following image includes the 95th percentile of the duration of contacts aggregated by day and by CoreMedia CID:

percentile

To calculate the 95th percentile, Contact Center and Analytics Studio sorts the contact durations as shown in the following table:

Day of contact (DD)DurationPosition (k)
150:00:001
150:04:092
170:04:123
150:04:394
170:04:495
150:05:026
170:05:387
170:05:488
170:06:239
170:06:4910
170:06:5911
170:07:5612
170:08:4513
170:09:3214
170:09:3815
170:11:1116
150:11:2517
170:11:3018
170:16:4619
150:17:3320

Then, it uses the following formulas:

I = .95 * (N - 1) + 1
k = floor(I)
d = decimal_part(I)

.95 Percentile = Xk + d * (Xk+1 - Xk)

Where:

  • I is the position of the 95th percentile.
  • N is the number of values in the list.
  • k is the position in the list.
  • d is the value used for the interpolation.
  • Xk is the value in the position k.
  • Xk+1 is the value in the position k+1.

Note that, if the value calculated for I is an integer, the value of the 95th percentile is the value in the position Xi.

For the values in the table above, Contact Center and Analytics Studio calculates the 95th percentile as follows:

I = .95 * (20 - 1) + 1 = 19.05
k = floor(19.05) = 19
d = decimal_part(19.05) = 0.05

.95 Percentile = X19 + 0.05 * (X20 - X19) = 0:16:46 + 0.05 * (0:17:33 - 0:16:46) = 0:16:49

The following image shows the percentile for day 15 and day 17:

150:04:092
150:04:393
150:05:024
150:11:255
150:17:336

For the values in the table above, Contact Center and Analytics Studio calculates the 95th percentile as follows:

I = .95 * (6 - 1) + 1 = 5.75
k = floor(5.25) = 5
d = decimal_part(5.25) = 0.75

.95 Percentile = X5 + 0.75 * (X6 - X5) = 0:11:25 + 0.75 * (0:17:33 - 0:11:25) = 0:16:01

170:09:3811
170:11:1112
170:11:3013
170:16:4614

For the values in the table above, Contact Center and Analytics Studio calculates the 95th percentile as follows:

I = .95 * (14 - 1) + 1 = 13.35
k = floor(13.35) = 13
d = decimal_part(13.35) = 0.35

.95 Percentile = X13 + 0.35 * (X14 - X13) = 0:11:30 + 0.35 * (0:16:46 - 0:11:30) = 0:13:21

Calculating change rates in a multi-dimension metrics panel

The percentage below each metric represents the change rate between the values of the metric in two consecutive periods. To calculate the change rates of the metrics, Contact Center and Analytics Studio compares the values of the metrics in period N and period N-1.

Contact Center and Analytics Studio calculates the change rates of the metrics based on the following formula:

     100 * (metric in period 2 - metric in period 1)
% =  ----------------------------------------------
                  metric in period 1

In the following image, the metric panel shows the number of visits, pages requests, and unique visitors of the documentation site during the month of February 2025.
