For instance, if you take an average of a 0,1 variable, the result is the proportion of 1s in the distribution. To illustrate dummy variables, consider the simple regression model for a posttest-only two-group randomized experiment.
President Barack Obama has already played nearly eight times as many rounds of golf during his presidency as President George W. Bush did throughout his eight years in office, according to noted presidential chronicler of all things numerical, CBS Newsâ Mark Knoller.
Trump, who owns 17 golf courses worldwide, continued: âI donât have time for that. I love golf, I think itâs one of the greats, but I donât have time.â. Itâs unclear whether Trumpâs statement that Obama played more golf than Woods last year is true or not. Itâs likely, however, that a lot of golf aficionados played more rounds of golf than Woods over the last year, as the 39-year-old pro spent much of his time recovering from injury. Not counting practice rounds, Woods played only 32 rounds on the PGA Tour in the 2015 calendar year.
