In the initial topic in basic physics in school and college, the concept of analysing a measurement error needs to be understood by students. This paper proposes the use of various sensors on smartphones for statistical error analysis which usually uses the classical method with repeated measurements. The smartphone sensors used were light, acceleration, and magnetometer sensors. The data from the sensor recording fluctuations for 10 s were analysed for the simple statistical figures and error. The experiment used three different conditions, namely placing the smartphone on a stable table, holding it with your hand, and bringing it closer to a notebook that played a 650 Hz tones. The experimental findings, the experimental conditions (environmental and blunder), and the specifications of the instrument affect the error. Students also can tell that the sensor takes repeated measurements so that it shows fluctuation data. This research contributes to offering the use of the latest technology, namely smartphones, for statistical error analysis for physics students. © 2021 IOP Publishing Ltd.
