A team must show how a speech model's error rate varies across 12 recording conditions, and they want the audience to see both the typical value and the spread within each condition. Which chart form fits?
選択肢
- A box plot per condition, which shows the median and the spread side by side.
- A pie chart of the share of errors by condition, so each slice shows how much of the total error that condition contributed.
- A line chart with condition on the horizontal axis, so the 12 conditions join into a trend the audience can follow.
- A bar chart of the mean error rate per condition, with the bars ordered from lowest to highest so that the audience can immediately identify the conditions that need attention and compare their heights against each other.
