SC511 Verifying the truth of numerical statements using the fx-82/100AU PLUS

This short video shows how to verify the truth, or otherwise, of numerical statements, using a Casio fx-82/100AU PLUS. The verification is performed on an exact trigonometric ratio and a surd simplification.


SC322 Equation of exponential model of ‘best fit’

This short video shows how to calculate the equation of the exponential model of ‘best fit’, using a Casio fx-82/100AU PLUS. This calculation is performed on atmospheric carbon data. Comparison is made with a linear model using Pearson’s r.


SC321 Equation of regression line of best fit using fx82/100AU PLUS

This short video shows how to calculate the equation of the regression line of ‘best fit’, using a Casio fx-82/100AU PLUS. This calculation is performed on length of spring under suspension data. An extrapolation is made.


SC312 Summary statistics frequency table using fx82/100AU PLUS

This short video shows how to calculate univariate summary statistics using a Casio fx-82/100AU PLUS. Calculated are the mean, standard deviation and five number summary of the outcomes of a probability experiment in a frequency table form.


SC311 Summary statistics raw data using fx82/100AU PLUS

This short video shows how to calculate univariate summary statistics using a Casio fx-82/100AU PLUS. Calculated are the mean and median of raw rental data.  


SC121 Generating random numbers using the fx-82/100AU PLUS

This short video shows how to generate random numbers, using a Casio fx-82/100AU PLUS. The generation of uniformly distributed pseudo random integers is used to investigate a probabilistic scenario, the outcome of summing three four-sided dice repeatedly.
