Honest investigation work sorts evidence into three piles: what you collected, what you were given and what you do not have. Writing only from the first two keeps every sentence defensible.
This page supports geographical investigation in SPM Geography. Your school sets the task, so confirm requirements with your subject teacher.
What does this look like in real life?
A student might say: “The group took the measurements, I was absent, and now I have to write the report.” Another says: “Our numbers looked odd, so I changed a few to make a neat pattern.”
Both feel like small problems, yet each turns the report into something the evidence does not support. The honest alternatives are easy to state.
Why does the pressure appear?
Three situations tend to cause it.
- Time is short, so writing a plausible result seems faster than explaining a gap.
- The data does not show the pattern the textbook promised.
- A missing day or site visit leaves a hole in the method.
A three-pile evidence plan
Before writing, sort every statement you want to make.
| Pile | Meaning | How to write it |
|---|---|---|
| Collected | You recorded it yourself | “I counted 27 pieces of litter at stretch A.” |
| Supplied | Your teacher or a source gave it | “The supplied table shows 12 pieces at stretch B.” |
| Not available | No data exists for it | “Weather was not recorded, so its effect cannot be judged.” |
Worked example
This is a worked example. A student was absent on the day a class measured soil moisture at two sites. The teacher supplied the class results: site X 38% and site Y 24%.
An honest paragraph reads: “The class data supplied by my teacher shows that site X had soil moisture of 38% and site Y had 24%, a difference of 14 percentage points (38 − 24). I did not take these readings myself. The data covers one day only, so a pattern across different days is not shown.”
A fabricated version might read: “I measured the soil at 9.00 a.m. and saw that it had rained the night before.” Neither the time nor the rain was recorded by this student, so the sentence invents observations.
What can you do this week?
- Write your question and method in one paragraph before touching the results.
- Mark every number as collected or supplied, in brackets.
- Draw your graph with the graph evidence and fair-comparison lab as a guide to fair comparison.
- Write two limitations using the pattern in explaining limitations without inventing observations.
When could one-to-one tuition help?
A teacher can explain how to word a question, choose a sampling method and read a graph, which are skills you need before the report. The fieldwork and the final write-up remain your own, and your school decides how it is assessed.
