Distribution and Measures of Center

What are the three main aspects to consider when describing the distribution of quantitative data?

• Shape, color, and size

• Shape, center, and spread

• Mean, median, and mode

• Outliers, gaps, and clusters

What does it mean for quantitative data to be "skewed right"?

• The data is evenly distributed across all values.

• The tail of the distribution extends towards the left side.

• The tail of the distribution extends towards the right side.

• The data forms a perfect bell curve.

Which measure of center is generally preferred for describing skewed quantitative data?

• Mean

• Median

• Mode

• Range

Which measure of spread is typically used for symmetric quantitative data?

• Range

• InterQuartile Range (IQR)

• Standard Deviation

• Median
