Let’s see how to reshape array in NumPy using the np.reshape() method, which changes array dimensions while preserving total elements and supports order and copy parameters.
-
NumPy’s np.sqrt() function makes it easy to calculate square root in NumPy for entire arrays, applying the square root operation element-wise to 1D or multi-dimensional arrays. Let’s see how to calculate square root in Numpy Python module.

This guide shows how to calculate standard deviation in NumPy using np.std(), supporting both population standard deviation (default ddof=0) and sample standard deviation (ddof=1). Standard deviation is a statistical measure that quantifies the dispersion or spread of a dataset around its mean (average) value. A low standard deviation indicates that the data points tend to be close to the mean, while a high standard deviation signifies that the data points are spread out over a wider range.
-
This guide shows how to calculate variance in NumPy using the np.var() function, which handles both population variance (default) and sample variance with the ddof parameter. Variance is a key statistical measure that helps to understand how data points are spread out.

Let’s see how to add a button in Python Tkinter using the Button widget, which is the standard way to create clickable buttons in Python GUI applications.

Deciles divide a dataset into ten equal parts, each representing 10% of the data. For example, the first decile represents the point below which 10% of the data falls, the second decile represents the point below which 20% of the data falls, and so on. Let’s see how to calculate deciles in Python using the statistics.quantiles function with n=10, which returns the cut points that split your data into ten equal parts.
-
Let’s see how to calculate quartiles in Python using the statistics.quantiles function for Q1, Q2, and Q3, and NumPy to compute the interquartile range (IQR).

Mode represents the single most frequent value in a list, while multimode provides a list of all the values that occur with the highest frequency. In statistical analysis, the mode is a measure of central tendency that identifies the most frequently occurring value in a dataset. However, datasets can sometimes exhibit multiple modes, where two or more values share the highest frequency. In such cases, the multimode becomes a valuable descriptive statistic, providing a more complete picture of the data’s distribution by highlighting all values that achieve this maximum frequency. This tutorial shows how to calculate multimode in Python using…

This guide shows how to calculate geometric mean in Python using the statistics module, NumPy logarithmic method, or SciPy’s gmean function for data analysis tasks. The geometric mean is a measure of central tendency that is useful for dealing with data that has a wide range of values and is often used in finance, biology, and other fields.
-
The harmonic mean is a type of average useful for rates and ratios, and this guide shows how to calculate harmonic mean in Python using the built-in statistics module, SciPy, or manual formulas. Let’s see how to calculate harmonic mean in Python.
