Verified step by step guidance

1. Understand the types of data: Qualitative data refers to categorical data that describes qualities or characteristics, while quantitative data refers to numerical data that can be measured or counted.
2. Recall the purpose of a line chart: Line charts are typically used to display data points connected over a continuous interval or time, making them ideal for showing trends in quantitative or continuous data over time.
3. Consider the nature of qualitative data: Since qualitative data represents categories without inherent numerical order or continuity, it does not suit the continuous or ordered nature required for line charts.
4. Compare with other chart types: For qualitative data, bar charts or pie charts are more appropriate because they effectively display categorical differences without implying continuity.
5. Conclude that line charts are not recommended for qualitative data because they are designed to show trends or changes over continuous or ordered numerical data, which qualitative data lacks.
