    How to Calculate Standard Deviation in NumPy (np.std with ddof, axis, and Population/Sample Examples)

    March 18, 2021

    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.

    How to Calculate Deciles in Python Using statistics.quantiles (Decile Definition and Example)

    March 2, 2021

    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.

    How to Calculate Multimode in Python Using the statistics Module (Mode vs Multimode Explained)

    March 2, 2021

    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…
