What Do the Values in a Correlation Matrix Represent?
The values in a correlation matrix range from -1 to 1. A value of 1 indicates a perfect positive correlation, meaning as one variable increases, the other also increases. A value of -1 indicates a perfect negative correlation, meaning as one variable increases, the other decreases. A value of 0 indicates no correlation. In nanotechnology, these values can help identify which properties are most strongly related, guiding material design and experimentation.
