Revision of Symmetric and Skewed Data

Learners will be able to:

• Identify the three main shapes of data distributions: symmetric, positively skewed (right-skewed), and negatively skewed (left-skewed). • Describe the characteristics of a symmetric distribution in terms of the mean, median, and mode. • Explain how a negatively skewed distribution affects the relationship between the mean, median, and mode. • Identify the effect of a positively skewed distribution on the position of the mean, median, and mode.
