Getting into NumPy Basics

bookBasic Statistical Operations

NumPy offers a suite of functions for executing basic statistical operations on NumPy arrays, making it indispensable for data analysis. Key functions include:

  • mean(): Computes the mean (average) of array elements;
  • median(): Determines the median (middle value) of array elements;
  • std(): Calculates the standard deviation, measuring the spread of the array elements;
  • var(): Assesses the variance, indicating the variability of array elements;
  • min(): Identifies the minimum value within an array;
  • max(): Locates the maximum value within an array;
  • argmin(): Finds the index of the minimum value in an array;
  • argmax(): Discovers the index of the maximum value in an array.
