In this video, I pretend to be a gym owner who is tracking the ages of people using the gym. I use this data and represent it on a stem and leaf diagram. We then interpret the data, working out what we how we can optimise the experiences of all in the gym.
I also calculate some basic statistics like mean, median and mode in this video.
