SQL> SELECT a.sper_status_text, COUNT ( * )
2 FROM (SELECT sper.assettxt,
3 CASE
4 WHEN sper.sper_status_text = 'Affirmed Evaluation'
5 THEN
6 'Affirmed Evaluation'
7 WHEN sper.sper_status_text LIKE 'Updated - Evaluated Up%'

15 END
16 sper_status_text
17 FROM zzcus.zzcus_sper_data sper
18 WHERE sper.sper_dates = '20100801--20100831'

You can get it like this. By using MODEL clause,
SQL>
SQL> CREATE TABLE ZZCUS_SPER_DATA1
  2  (
  3     SPER_STATUS_TEXT VARCHAR2 (30)
  4    ,TASK_INQUIRY_TYPE VARCHAR2 (100)
  5  );
Table created.
SQL>
SQL> INSERT INTO ZZCUS_SPER_DATA1
  2       VALUES (
  3                 'Data Updated', 'Descriptive Data Challenge - Maturity date / Redemption date');
1 row created.
SQL>
SQL> INSERT INTO ZZCUS_SPER_DATA1
  2       VALUES ('Data Updated', 'Descriptive Data Challenge - Ticker / Local Code');
1 row created.
SQL>
SQL> SELECT *
  2    FROM (  SELECT A.SPER_STATUS_TEXT, COUNT (*) CNT
  3              FROM (SELECT CASE
  4                              WHEN SPER.SPER_STATUS_TEXT = 'Data Confirmed'
  5                              THEN
  6                                 'Data Item Confirmed'
  7                              WHEN SPER.SPER_STATUS_TEXT LIKE 'Data Updated'
  8                              THEN
  9                                 'Data Item Updated'
10                              ELSE
11                                 'Other Responses'
12                           END
13                              SPER_STATUS_TEXT
14                      FROM ZZCUS_SPER_DATA1 SPER
15                     WHERE 1 = 1
16                           AND SPER.TASK_INQUIRY_TYPE LIKE 'Descriptive Data Challenge%') A
17          GROUP BY A.SPER_STATUS_TEXT
18          ORDER BY (CASE
19                       WHEN A.SPER_STATUS_TEXT = 'Data Item Confirmed' THEN 1
20                       WHEN A.SPER_STATUS_TEXT = 'Data Item Updated' THEN 2
21                       WHEN A.SPER_STATUS_TEXT = 'Other Responses' THEN 3
22                       ELSE 4
23                    END))
24  MODEL
25     DIMENSION BY (SPER_STATUS_TEXT)
