Question 1 · 1 mark · Difficulty 1/3
During an investigation into water quality in a Jamaican river, a student collected data on pH levels at five different sites. The pH values recorded were: 6.8, 7.2, 6.5, 7.0, and 6.5. What is the mode of this data set?
- 7.2
- 6.5
- 6.8
- 7.0
Show answer & explanation
✓ Answer: B — 6.5
5). Award 1 mark for correctly identifying 6.5 as the mode. The mode is the value that occurs most frequently in a data set. 6.5 appears twice while all other values appear only once. C, D, and A are incorrect as these values each occur only once.
Question 2 · 1 mark · Difficulty 1/3
Students at a secondary school in Guyana surveyed the types of renewable energy sources used in their community. They found: solar (35 households), wind (10 households), hydroelectric (5 households), and biomass (15 households). Which type of graph would be MOST suitable to show the proportion of each energy source used?
- Line graph
- Histogram
- Pie chart
- Scatter graph
Show answer & explanation
✓ Answer: C — Pie chart
Award 1 mark for identifying pie chart as appropriate for showing proportions of a whole. A is incorrect — line graphs show continuous change over time. B is incorrect — histograms show frequency distribution of continuous data. D is incorrect — scatter graphs show relationships between two variables.
CXC CSEC Integrated Science: Scientific Method and Skills FAQ
Is Kramizo free for CXC CSEC students preparing for Integrated Science?
Yes — completely free. Every student gets 45 questions a day on the free plan, with no card required and no trial countdown. That free quota works across every subject and every topic in our bank, so you can mix Scientific Method and Skills practice with other Integrated Science topics or even switch to a totally different CXC subject without paying anything. Kramizo's optional Pro plan removes the daily cap and adds detailed progress analytics, but the free tier is the real product — used by thousands of GCSE, IGCSE and CSEC students.
Are the Scientific Method and Skills questions aligned to the official CXC CSEC Integrated Science syllabus?
Every question is written against the published CXC CSEC Integrated Science specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real CXC paper. Explanations are written in the style of official examiner mark schemes — they tell you what is being awarded marks and why distractors are wrong, not just whether you got it right. The bank is continually refined to match the latest syllabus updates from CXC.
How is Scientific Method and Skills typically tested on CXC CSEC Integrated Science papers?
Scientific Method and Skills appears across multiple question types on real CXC CSEC Integrated Science papers — most commonly as multiple-choice questions in the objective section, structured short-answer questions in the main paper, and occasionally as part of an extended response. Kramizo's practice bank reflects that mix: 4-option MCQs, true/false statements, fill-in-the-blank key terms, multi-select questions, and ordering questions. Working through the bank gives you exposure to every question style examiners actually use.
