Daily phone screen time-Kids vs Adults
This is a chart that shows the daily phone screen time of 50 adults, 22 and over, and 50 kids, 21 and above. As shown, the kids graph (blue) is longer than most of the red lines (representing the adults daily phone use). This means that majority of kids spend more time on their phones than the majority of adults in hours per day.

Adults Vs. Kids Phone Screen Time
This graph represents a random sample of kids ,21 or below, and adults, 22 and above, screen time on their cell phone per day. As you can see, the kids graph has a higher median and mean than the adults in hours. Also the kids dot plot has the highest phone screen time per day, 12 hours. The range is the same for both. Finally the distribution for the kids graph is mostly symmetrical whilst the adult graph is skewed right meaning there are more adults that spend less time on their phone.
