Data parameters can now be created with bivariate data. $b=data((11,12)(15,19)(21,28)(13.2,19.4),(8,16)) Bivariate data is entered as separate data points, wrapped in parentheses, which are then (optionally) separated with your normal separator. New RandBivariate Parameter Often, the best way to create random … Continue reading →

Data parameters can now support grouped data. $g=data(10~20:2,20~30:6,30~40:4,40~50:2) This data parameter is equivalent to this frequency table. Data Frequency 10 < x <= 20 2 20 < x <= 30 6 30 < x <= 40 4 40 < x … Continue reading →

Data parameters can now support frequency tables. $p=data(10:1, 11:3, 12:5, 13:4, 14:3, 15:2) This data parameter is equivalent to this frequency table. Data Frequency 10 1 11 3 12 5 13 4 14 3 15 2 Each entry in the … Continue reading →

The inclusion of data parameters and random number generating parameters has prompted more statistical functions which can calculate summary statistics. For example. If $p=randnormal(50,15,30), $p will return a data parameter with 30 random numbers which have been taken from a … Continue reading →

We have implemented a new parameter and a number of new calculator commands that allow you to work with words. These allow you to implement probability questions like: If you randomly select a letter from the word MISSISSIPPI, what is … Continue reading →
