arris a 1D NumPy array containing the values[2, 7, 5, 8, 9, 4]. Thenumpy.mean()function is then applied to calculate the arithmetic mean of the elements in the 1D array, and the result is stored in the variablearr1. Finally, the mean value is printed on the console....
Python’s statistics module provides built-in functions for calculating different types of averages such as mean, median, and mode. Let’s take a look at an example that demonstrates the usage of the mean() function from the statistics module to calculate the average of a given list of numb...

The NumPy variance function,numpy.var(), is used to calculate the variance of a dataset. Variance measures the dispersion or spread of a set of values. In statistics, it is the average of the squared differences from the Mean. Can numpy.var() handle multi-dimensional arrays?
