When to Use Slider vs Number Input

Use Slider when you want annotators to make quick, intuitive selections on a continuous scale
Use Number Input when you need precise values or when the range is very large

Best Practices

Set sensible defaults - Place the default at a meaningful position (often the midpoint)
Use endpoint labels - Help annotators understand what the scale represents
Choose appropriate step sizes - Smaller steps for fine-grained distinctions, larger for coarse ratings
Keep ranges intuitive - 0-100 or 1-10 are familiar to most annotators
