IB Mathematics Internal Assessment
No correlation, no trend, a model that fits badly, a test that comes back with nothing to report. Students read that as failure and start looking for a new topic. Often it is neither the end of the IA nor a reason to fake a result. It is a decision point.
The reassurance: the IA does not reward a tidy result. It rewards mathematics that is chosen, understood and honestly evaluated. An outcome that surprised you can give you more to say about reflection and use of mathematics than a clean one ever would.
The warning: "the results show nothing" only helps you if you can explain why. A flat result with no diagnosis reads as an unfinished piece of work. A flat result with a careful diagnosis reads as a student who thinks like a mathematician.
There are four different situations hiding behind the same feeling. Each needs a different response, so sort yours before you touch anything.
You asked a fair question, collected sound data, and the answer is that the two things are not linked in any way your method can detect. This is a genuine finding. Your job is to show it is not an accident of the method.
Too few points, too narrow a range, values rounded so coarsely that variation disappears, or a measure that does not capture what you meant. The relationship may exist. Your data was never in a position to show it.
A linear model on something curved, a test whose conditions your data does not meet, a variable treated as continuous when it is really a set of categories. The nothing comes from the tool, not the world.
A unit mismatch, a column shifted by one row, a formula dragged down a spreadsheet with a reference that moved. Check this before anything dramatic. It is more common than students like to admit.
Each criterion asks something different, and a flat result touches them differently.
Dropping the awkward points without a stated reason, or trying test after test until one gives a result, is bad practice and it shows. Removing a value needs a justification you can defend, given in the work.
Drawing a line through a shapeless cloud and calling it a trend will be spotted by any experienced reader. Say what the data shows, not what you hoped it would.
The dead end is often the most valuable material you have. Cutting it to make the work look smooth throws away your best evidence of thinking.
Sometimes the honest answer is that the question cannot be rescued in the time left. Signs of that: the data cannot be collected again, the method that would suit it is far beyond your course, and there is no version of the question you still care about. Then narrow or change the question, keep the mathematics you have already built, and carry the lessons from the first attempt into the new one. Tell your teacher early. A change made with weeks to spare is a plan. A change made in the last few days is a rescue.
Stuck with a result that goes nowhere?
Send me your question, what you did and what came out. I read real submitted explorations every year and I will tell you which kind of nothing you have, and whether it can be rescued.

These pages are free and stay free, but they are general and your IA is not. Send me your research question, or whatever exists so far, and I will tell you in writing whether the topic has a ceiling on it, where the marks are going, and what to change first. That costs nothing and it comes back within 24 hours.

If you then want the whole draft reviewed properly against all five criteria, that is the paid one, and it is refunded if it does not name at least three specific things to fix.

I never write any part of it. Not a sentence, not a calculation, not your data. Under 18: a parent buys this and the thread is with them. I do not work with students at my own school.
