These Analytical Ability items (Professional level) combine tables or short data with questions about what is shown, what can be concluded, and what is merely assumed. On the CSE-PPT, careful reading of the chart beats flashy computation.
How to approach
- Read titles, units, and footnotes first. “In thousands,” “% of row,” and year labels change answers.
- Answer only what is asked. “Highest” is not “highest percent growth.”
- Separate data vs. conclusion. A conclusion must be forced by the numbers; an assumption is an unstated extra belief.
- Compute only the needed cells. Don’t average the whole table if one comparison suffices.
- Watch percent vs. count. A category can lead in percent while trailing in headcount.
Worked example
Table (original): Applicants served at a CSC field desk (one Saturday)
| City | Morning | Afternoon |
|---|---|---|
| Cebu | 40 | 55 |
| Davao | 35 | 50 |
| Iloilo | 45 | 30 |
Question: Which city served the most applicants that day?
- A.Cebu
- B.Davao
- C.Iloilo
- D.Cannot be determined
Work: Totals: Cebu 95, Davao 85, Iloilo 75. Answer: A. Cebu. (Iloilo led the morning only.)
Common traps
- Row/column mix-up — Comparing morning Cebu to afternoon Davao as if they were totals.
- Percent of wrong base — Dividing by the grand total when the stem means “percent of that city’s applicants.”
- Over-conclusion — Claiming “Iloilo is least prepared nationally” from one desk’s Saturday counts.
- Assumption disguised as fact — Options that add motives (“because of traffic”) not in the data.
- Graph optical tricks — Bars that start above zero or pictograms that aren’t one-to-one with counts.
Quick practice
- Using the table above, how many more did Cebu serve than Davao all day?
- A.5 B. 10 C. 15 D. 20
Answer: B — 95 − 85 = 10.
- Which statement is a safe conclusion from the table alone?
- A.Iloilo’s staff is undertrained.
- B.Davao’s afternoon count exceeded its morning count.
- C.Cebu always leads every Saturday.
- D.Nationwide turnout fell.
Answer: B — 50 > 35; A/C/D go beyond the data.
