The margin of error is usually defined as the ''radius'' (or half the width) of a confidence interval for a particular statistic from a survey. One example is the percent of people who prefer product A versus product B. When a single, global margin of error is reported for a survey, it refers to the maximum margin of error for all reported percentages using the full sample from the survey. If the statistic is a percentage, this maximum margin of error can be calculated as the radius of the confidence interval for a reported percentage of 50%.

Two months before filming, Lori Petty, Reeves and Swayze trained with former world class professional surfer Dennis Jarvis on the Hawaiian island of Kauai. Jarvis remembers, ''Patrick said he'd been on a board a couple of times, Keanu definitely had not surfed before, and Lori had never been in the ocean in her life.'' Shooting the surfing sequences proved to be challenging for both actors with Swayze cracking four of his ribs. For many of the surfing scenes he refused to use a stunt double as he never had one for fight scenes or car chases. He also did the skydiving scenes himself and the film's aerial jump instructor Jim Wallace found that the actor was a natural and took to it right away. The actor ended up making 55 jumps for the film. Swayze actually based aspects of his character after one of his stunt doubles, Darrick Doerner, a top big wave surfer. After learning to surf for the film, Reeves took a liking to it and took it up as a hobby.

did patrick swayze surf in the movie point break?

A: yes
