A boxplot would be the best choice to determine if the data is normally distributed. A boxplot displays the median, quartiles, and outliers of the data, allowing for easy identification of any skewness or symmetry in the distribution. This is more effective in identifying a distributional pattern than a bar chart, scatter plot, or time-series plot.
