For sample adults who had participated in tennis in the past 2 weeks (EXTENNIS), EXTENNISMIN reports the average number of minutes respondents had spent playing tennis each time they had engaged in that activity over the past 2 weeks.

After determining that a respondent participated in tennis, respondents were first asked, "How many times in the past 2 weeks did you play tennis?" (EXTENNISNO). They were then asked, "On the average, about how many minutes did you spend playing tennis each time?" EXTENNISMIN reports the answer to this last question.
