distribution
This cell prints descriptive statistics and plots a frequency distribution of the samples currently in the text field of cell "data".
There are ten bins in the frequency distribution. The plot shows the percentage of numbers falling within each bin versus the bin number.
|
exponential
This cell generates Num random numbers that are exponentially distributed with the exponential distribution parameter lambda.
The numbers are written to the text field of cell data, which is the input field for the script in cell distribution, which plots the distribution function and prints descriptive statistics.
For a different collection of numbers, change the seed in the first call to the Rand() function.
WARNING: The execution of this script overwrites the contents ofthe text field of cell data. But first it copies the contents of the text field of that cell to the cell backup.

This web provides some handy statistical tools.
Enter a collection of numbers into the text field of cell "data", and you can get descriptive statistics, and a plot of frequency distribution by executing the script of cell "distribution".
For descriptive statistics only, execute cell "stats".
To generate random numbers from known probability distributions, execute the scripts of cells "uniform","normal", or "exponential". These scripts will overwrite the contents of the text field of cell "data", so save them first if you want to keep them.

normal
This cell generates Num random numbers that are normally distributed with a mean close to the value in cell normMean, and a standard deviation that is close to the value in cell normSigma.
The numbers are written to the text field of cell data, which is the input field for the script in cell distribution, which plots the distribution function and prints descriptive statistics.
For a different collection of numbers, change the seed in the first call to the Rand() function.
WARNING: The execution of this script overwrites the contents ofthe text field of cell data.

normMean
This is the mean to use in the generation of normally distributed random numbers

normSigma
This is the standard deviation to use in the generation of normaly distributed random numbers (see cell normal)

Num
The value field of this cell contains the number of data items to write into the text field of cell "data" from the normal, exponential, or uniform cells.

uniform
This cell generates Num random numbers that are uniformly distributed on the interval [uniMin,uniMax]
The numbers are written to the text field of cell data, which is the input field for the script in cell distribution, which plots the distribution function and prints descriptive statistics.
For a different collection of numbers, change the seed in the first call to the Rand() function.
WARNING: The execution of this script overwrites the contents ofthe data cell text field.
