which of the following can be observed from a histogram? more than one answer may be correct.
the shape of the distribution.
the approximate number of observations.
the relationship between two variables.
the spread of the data.

Explanation:

• A histogram visually displays the frequency distribution of a single variable, so its shape (e.g., symmetric, skewed) is directly observable.
• By summing the frequencies of all bars, the approximate total number of observations can be found.
• Histograms only represent one variable, so they cannot show relationships between two variables (this is done with scatterplots).
• The spread of the data (range, how spread out bars are) is visible from the x-axis scale and bar placement.

Answer:

• The shape of the distribution.
• The approximate number of observations.
• The spread of the data.
