The mean age of all the U. S Vice Presidents when they took office would be a parameter sample population or statistic

Holding the least understood, most ridiculed, and most often ignored constitutional office in the federal government, American vice presidents have included some remarkable individuals. Fourteen of the former vice presidents became president of the United States—more than half of them after a president had died. One defeated the sitting president with whom he served. One murdered a man and became a fugitive. One joined the Confederate army and led an invasion of Washington, D.C. One was the wealthiest banker of his era. Three received the Nobel Peace Prize and one composed a popular melody. One served as a corporal in the Coast Guard while vice president. One had cities in Oregon and Texas named after him. Two resigned from the office. Two were never elected by the people. One was the target of a failed assassination plot. Another was mobbed in his car while on a goodwill mission. Seven died in office—one in his room in the U.S. Capitol and two fatally stricken while on their way to preside over the Senate. And one piano-playing vice president suffered political repercussions from a photograph showing him playing that instrument while a famous movie actress posed seductively on top of it.
