Explanation:

1. Independent Variable

The independent variable is the one manipulated in an experiment. Here, the number of wire wraps (or coils) around a core is controlled, so it’s the independent variable.

2. Dependent Variable

The dependent variable depends on the independent variable. The magnetic strength (measured by paperclips picked up) changes with the number of coils, so it’s the dependent variable.

3. Possible Research Question

A research question connects the variables: “How does the number of wire wraps (coils) around a core affect the magnetic strength (number of paperclips picked up)?”

4. Trend in the Data

From the scatter plot, as the number of coils (x - axis) increases, the number of paperclips (y - axis) generally increases. This shows a positive correlation—more coils correlate with stronger magnetic strength (more paperclips picked up).

5. Label for the Y - Axis

The y - axis measures the magnetic strength via “Number of Paperclips Picked Up” (since paperclips are a proxy for magnetic pull).

6. Control (from “What control [from ‘No Core’?]”)

Assuming a “no core” condition is a control, the control would be a setup with 0 wire wraps (or no coil) around the core, to compare against setups with coils. This isolates the effect of coils on magnetic strength.

Answer:

s:

• Independent Variable: Number of wire wraps (coils) around the core
• Dependent Variable: Number of paperclips picked up (magnetic strength)
• Possible Research Question: How does the number of wire wraps around a core affect the number of paperclips it can pick up (magnetic strength)?
• Trend: As the number of wire wraps (coils) increases, the number of paperclips picked up (magnetic strength) generally increases (positive correlation).
• Y - Axis Label: Number of Paperclips Picked Up
• Control (if “No Core” is the control): A setup with 0 wire wraps (or no coil) around the core (to compare magnetic strength without coils).
