WebNow you can use NumPy, SciPy, and pandas correlation functions and methods to effectively calculate these (and other) statistics, even when you work with large datasets. You also know how to visualize data, … WebApr 11, 2024 · In this example, we create two sample datasets x and y, and then use the corrcoef() function from NumPy to calculate the correlation between the two datasets. The [0, 1] indexing is used to select the correlation value between the first and second datasets. The corrcoef() function returns the correlation value as a float.
