Graph of a Probability Distribution. A probability distribution can be graphed, and sometimes this helps to show us features of the distribution that were not apparent from just reading the list of probabilities. The random variable is plotted along the x-axis, and the corresponding probability is plotted along the y-axis.
Manic-depression: Alternating moods of abnormal highs (mania) and lows (depression). Called bipolar disorder because of the swings between these opposing poles in mood. A type of depressive disease.

Bipolar disorder, also known as manic depression, is a treatable illness involving extreme changes in mood, thought, energy, and behavior. A person with bipolar disorder has moods that usually alternate between mania, or extremely âupâ mood, and depression, or extremely âdownâ mood. This change or âmood swingâ can last for hours, days, weeks, or even months. Typically, someone with bipolar disorder experiences one or two cycles a year, with manic episodes generally occurring in the spring or fall.
