The experiment consists of spinning a spinner and recording the angle (measured clockwise from the starting position) and the sector number . The number of sectors in the spinner can be varied with the scrollbar. The probability of each sector (which is proportional to the area of the sector) can be set with the probability dialog. Type the probabilities into the textboxes, but be sure to press enter after typing each probability. The probability density function and moments of the random variable (the spinner score) are shown in blue in the distribution graph and recorded numerically in the distribution table. When the experiment runs, the empirical density function and moments are shown in red in the distribution graph and recorded in the distribution table. In single step mode, the spinner pointer actually spins, and a sound is played whose tone depends on the outcome.
