• Post an explanation ofwhat a normal distribution means, including its shape and features.
• Using the 'Calculate Areas' calculator in the Lane Resource, specify a mean, SD, and the area 'above' and state what the area is.
• Do the same for an area 'Below'.
• Explain what both of these areas mean and how the area changes when its above versus below.
