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.
The White House's reluctance to admit how much time the president is really spending on the golf course may be related to Trump's many comments criticizing Barack Obama for playing golf. I love golf, I think it's one of the greats, but I don't have time, Trump said during the campaign. Two hundred and fifty rounds, that's more than a guy who plays in the PGA Tour plays, Trump said of Obama in December 2015. He played more golf last year than Tiger Woods. We don't have time for this.
