1. a visual representation showing the relationship between scale and frequency in wavelet analysis or signal processing
Usage: technical; mathematics
2. a diagram or chart used in psychology to display the scalability of test items or responses
Usage: psychology; statistics

Examples

• The researcher created a scalogram to analyze the frequency components of the audio signal.
• The scalogram revealed distinct patterns in the wavelet coefficients across different time intervals.
• Psychologists use a scalogram to determine if survey items form a proper scale.
• The scalogram analysis showed that the test items were arranged in order of difficulty.
• Engineers examined the scalogram to identify noise patterns in the data.
• The scalogram displayed clear time-frequency relationships in the seismic data.
