Q: How do I try a free CXC Mathematics question?

Just tap any of the four options on this page — no signup, no card, nothing to install. You'll see the correct answer and a full mark-scheme-style explanation within a second. Each visit shows a fresh randomly-picked question from the live CXC CSEC Mathematics bank, so you can keep refreshing to try different ones before deciding whether to create a free account for daily access.

Q: Is Kramizo really free for CXC Mathematics students?

Yes — completely free. Every student gets 45 questions a day on the free plan, across any board and any subject, with no card required and no trial countdown. Kramizo's optional Pro plan removes the daily cap and adds analytics, but the free plan is genuinely free forever. We make money from the small percentage of students who choose to upgrade — not from selling data or ads.

Q: Are the Mathematics questions aligned to the CXC CSEC syllabus?

Every question is written against the published CXC CSEC Mathematics syllabus and reviewed for accuracy before being added to the bank. We match the command words (state, describe, explain, evaluate), mark allocations, and difficulty tier you'll see on real CXC past papers. Explanations are written in the style of official examiner mark schemes so students learn exactly what marks are being awarded for.

Question

A student in Trinidad surveyed 30 households about their monthly electricity consumption in kilowatt-hours (kWh). The consumption values ranged from 145 kWh to 890 kWh. What type of data has the student collected?

Accepted Answer

Continuous quantitative data — Award 1 mark for recognizing that electricity consumption measured in kWh can take any value within a range and is numerical. A is incorrect — while numerical, consumption can be measured to any degree of precision (e.g., 145.7 kWh), making it continuous not discrete. C is incorrect — nominal data involves categories without numerical value. D is incorrect — ordinal data involves ranked categories, not measured numerical values.

Answer

Continuous quantitative data

Answer

Nominal qualitative data

Answer

Discrete quantitative data

Answer

Ordinal qualitative data
