Tap a fruit button to add "one friend who likes this fruit." As the pictures stack up, you'll see at a glance which fruit is the most popular.
If you just hear which fruits your classmates like, it's hard to tell at a glance which one is most popular. But what if you lined up one picture for each fruit and counted them? You'd instantly see which fruit came up the most. Showing data with pictures or symbols like this is called a picture graph.
The core idea of a picture graph is "sorting" and "counting." First you sort the data into categories (apple or banana?), then count how many are in each category, and line up that many pictures — that's it. This process is the very first step of statistics. Tap the fruit buttons and watch the pictures stack up one by one to see which fruit is the most popular.
