Statistics & Probability

What you'll learn

Representing data with dot diagrams, histograms, and stem-and-leaf diagrams, finding the mean/mode/median, and working out the probability of a single event.

• The same data can be pictured three ways
• Read every bar (or every leaf) to find the total
• The mean is the total shared out equally
• The median is the middle value once the data is in order
• The mode is the value that occurs most often
• Probability of a single event, always in simplest form
