In this video I explain how to do the statistical analysis of a set of ungrouped data, determining the measures of central tendency (mean, median, mode), the quartiles, the frequency table, the measures of dispersion (variance, typical or standard deviation, coefficient of variation) and the main graphs (box and whisker diagram, bar diagram, frequency polygon and pie chart). At the end I show how to obtain those same results on the #Casio #Classwiz fx-991LA CW scientific calculator.
