Designed to work with CAS TI-Nspire calculators, this document is a quick and easy way to find seasonal indices, correct for seasonality, deseasonalise data, reseasonalise data, and find percentage changes for a range of different question styles. Specifically created for the VCE General Maths Units 1 - 4 study design, save this file to your CAS to save minutes of working out time during SACs and exams.

Designed to work with CAS TI-Nspire calculators, these documents provide a quick and easy way to find: Upper and lower fences to prove outliers Linear equations from 2 co-ordinates, from the r, sy, sx, x mean, and y mean, and predict values from the y-intercept and gradient (interpolation and extrapolation) Z-scores, the mean, standard deviation, and actual scores Normal distribution values from the mean and standard deviation Transformed data using quadratic, logarithmic, and reciprocal transformations on both the x and y axis’, and the relevant equations, correlation coefficients, and coefficients of determination Residual values, predicted values, and actual values Smoothed data using mean smoothing (2, 3, 4, 5, 6, 7, 8, and 9 mean smoothing) with and without centering Seasonal indices, correct for seasonality, deseasonalise data, reseasonalise data, and find percentage changes for 4, 5, 7, and 12 seasons, for up to 5 years Specifically created for the VCE General Maths Units 1 - 4 study design, save these files to your CAS to save minutes of working out time during SACs and exams.
