Question: Do people who go to bars and pubs a lot

Do people who go to bars and pubs a lot tend to have more friends? A recent GSS asked, “How often do you go to a bar or tavern?” The table shows results of ANOVA for comparing the mean number of good friends at three levels of this variable. The very often group reported going to a bar at least several times a week. The occasional group reported going occasionally, but not as often as several times a week.
