Investigators enrolled older adults into an exercise study that involved counseling, exercise classes, and reminders. Investigators are interested in several outcomes including "Physical activity at 6 months." At 6 months, the adults were questioned about their exercise activity in the last week, and their responses were categorized as "Low," "Moderate," or "High." For simplicity, we will call "Physical activity at 6 months" just "Activity." This table summarizes the proportion of participants in each category.
