Given the first type of plot indicated in each pair, which of the second plots could not always be generated from it?

 stem and leaf, dot plot


 histogram, dot plot


 stem and leaf, histogram


 dot plot, histogram


To determine which of the second plots could not always be generated from the first type, let's analyze each pair:

1. **Stem and Leaf Plot → Dot Plot**: A stem and leaf plot shows the distribution of data and the exact values. A dot plot, which also shows individual data points, can typically be generated from a stem and leaf plot by translating each leaf value into a dot.

2. **Histogram → Dot Plot**: A histogram represents data in intervals (bins), but it doesn't show individual data points, only the frequency of data within intervals. To create a dot plot from a histogram, you'd need the individual data points, which are not provided by a histogram, so this cannot always be generated.

3. **Stem and Leaf Plot → Histogram**: A histogram shows the distribution of data across intervals. Since a stem and leaf plot gives the exact values, you can group them into intervals to create a histogram.

4. **Dot Plot → Histogram**: A dot plot displays individual data points, and a histogram can be generated by grouping these points into intervals.

**Conclusion**: The second plot that cannot always be generated from the first is **Dot Plot from Histogram**.
