Correction to "Effects of Wall and Freespace Damping Levels on Virtual Wall Stiffness Classification"

Area of Science:

• Data visualization
• Scientific plotting
• MATLAB scripting

Background:

• Accurate data representation is crucial in scientific publications.
• Figure 5 in reference [1] presented specific data visualizations.
• Potential for errors in data transcription and plotting exists.

Purpose of the Study:

• To identify and correct a data plotting error in a published figure.
• To clarify the accurate representation of Information Technology (IT) metrics.
• To ensure the integrity of scientific data presentation.

Main Methods:

• Code review and analysis of plotting scripts in MATLAB.
• Comparison of intended data with plotted data in Figure 5.
• Identification of data assignment errors in plot generation.

Main Results:

• Figure 5 inadvertently plotted Information Technology (IT) metrics incorrectly.
• Subplots (b)-(d) displayed swapped data, with IT multiplied by 100 instead of the correct fraction.
• The error was a transcription mistake in assigning data to plot windows.

Conclusions:

• The identified error was limited to the visual representation in Figure 5.
• No underlying statistical analyses or other research findings were compromised.
• Correction of the visual error ensures accurate interpretation of IT performance metrics.
