Abstract
In this work, a descriptive statistics study will be carried out based on the practice of a simple pendulum, for which statistical analysis of the gravity relationship will be implemented based on the measurement of the period of a pendulum. To do this, the values of acceleration of gravity will be measured analytically and graphically, and sufficient data will be taken to make different statistical calculations including standard deviations, measures of central tendency, measures of dispersion, percentile, quartile, and graphing. as histogram and ogive. The results show that the calculated values of gravity present percentage errors about the established value of gravity, and it can also be seen that statistics contribute to the calculation of physical parameters.
Keywords: Simple pendulum, acceleration of gravity, descriptive statistics, timer with sensors, Arduino.
