First, think about what “limitation of experimental measurements” really means. When we do experiments, we’re trying to measure something as accurately as possible, but there are things that limit how accurate our measurements can be. These are things that introduce errors or uncertainty into our results.
Systematic errors are definitely a limitation. These are consistent errors that shift all measurements in the same direction. For example, if your meter rule is wrongly marked and every measurement reads 0.5 cm too long, that’s a systematic error. It limits your accuracy because no matter how carefully you measure, your results are always off by the same amount.
Random errors are also a limitation. These are errors that happen by chance. Maybe your stopwatch sometimes lags a tiny bit when you press start, or a small gust of wind moves your experimental setup. These errors make measurements fluctuate and limit precision, because repeated measurements won’t always give exactly the same number.
Human error is another limitation. This is when mistakes by the experimenter—like reading the scale wrong, recording a value incorrectly, or misaligning the measuring tool—cause inaccurate results. That’s definitely a limitation of experimental measurements, and it’s something JAMB loves to test.
Now, instrument resolution is different. The resolution of an instrument is essentially its smallest division or smallest value it can detect. It’s not an error or limitation caused by mistakes; it’s a property of the instrument itself. If a digital thermometer can only read to the nearest 0.1°C, that’s its resolution. You can still take perfect readings with it, and knowing the resolution actually helps you quantify uncertainty, not limit it in the same sense as errors do. That’s why JAMB picks B as “not a limitation” in this question. It’s a subtle distinction, but important: resolution tells you what you can measure, errors tell you what you can’t measure accurately.
Here’s a trick to remember for exams: think “errors are bad, limitations are annoying, resolution is neutral.” Systematic errors, random errors, and human errors all annoy you and limit your results. Resolution is just part of the tool—it’s neutral.
Human error is the correct answer because it is a personal mistake, not a physical limitation of measurement
But AI told me that is a limitations l of experimental measurements,AI said that it's systematic error but you said that it's instrument resolution
the Ai and the my school answer are not same, and I seem to lain towards the ai, be resolve
