Data distributions

Question 1

Normal distribution

Answer 1

• has a classic bell shaped curve
• occurs when certain variables are measured
• distributed in a way where most of the scores are clustered close to the mid point — the mean, mode and median are all in the exact midpoint

Question 2

Skewed distribution

Answer 2

• not distributed equally around the mean
• one tail is longer than another which signifies that there are a number of extreme values to one side or the other of the mid score
