Question

suppose you have a histogram that is symmetric with no outliers. what metric(s) are \best\ to report?
□ variance
□ median
■ standard deviation
□ iqr
□ mean

Explanation:

For a symmetric histogram with no outliers, the mean equals the median (both measure central tendency well), and standard deviation (not variance alone) is a good measure of spread (since it uses all data points, appropriate for symmetric distributions without outliers). Variance is less intuitive (squared units), IQR is better for skewed data/outliers.

Answer:

Mean, Standard Deviation
