Cuartiles, Deciles y Percentiles | Datos agrupados en intervalos | Ejemplo 2

Summary

This video tutorial explains how to calculate quartiles, deciles, and percentiles using grouped frequency tables. The instructor demonstrates step-by-step how to find these measures of position, using a real-life example based on exam scores of 100 students. The video covers key concepts like absolute frequencies, cumulative frequencies, and how to apply the formulas for each measure. The instructor emphasizes the importance of identifying the correct position in the cumulative frequency table, handling cases where values are found directly in the table, and using the right limits and amplitudes for accurate calculations. The tutorial ends with a practical exercise for the viewers to try on their own.
