A movie to show how the probability that a standard normal random variable lies within plus or minus a multiple of its standard deviation (that is, 1) varies with the value of the multiple.

normal_areas_movie(starting_multiple = 1, delta_multiple = 1, ndec = 3)

Arguments

starting_multiple

A non-negative numeric scalar. The value of the multiple used in the first plot.

delta_multiple

A numeric scalar. The amount by which the value of the multiple is increased/decreased after one click of the +/- button.

ndec

The number of decimal places to which to round the probability that is superimposed on the plot.

Value

Nothing is returned, only the animation is produced.

Details

The value of the multiple can be changed using the +/i buttons in the panel. For the purposes of this movie, the multiple cannot be increased above a value of 5.
