bookChallenge: Explore Voltage and Current Relationship

In engineering analysis, understanding the relationship between two variables—such as voltage and current in a circuit—is a key application of correlation analysis and scatter plotting. Correlation quantifies the degree to which changes in one variable are associated with changes in another. A scatter plot visually displays this relationship, allowing you to quickly assess whether the variables move together in a predictable way. In this challenge, you will explore the relationship between voltage and current using real-world engineering data.

Swipe to start coding

You are given two lists: voltage_data and current_data, which represent voltage and current measurements from a circuit. Your task is to:

  • Calculate the correlation coefficient between voltage_data and current_data.
  • Create a scatter plot of voltage_data (x-axis) versus current_data (y-axis).
  • Return both the correlation coefficient and a string describing the relationship as "strong", "weak", or "negligible" based on the absolute value of the correlation coefficient.

Steps:

  • Compute the correlation coefficient between voltage_data and current_data.
  • Plot the data using a scatter plot with appropriate axis labels and a title.
  • Determine if the relationship is "strong" (absolute correlation > 0.7), "weak" (absolute correlation > 0.3), or "negligible" (absolute correlation ≤ 0.3).
  • Return the correlation coefficient and the relationship description as a tuple.
