In this Python tutorial, you will learn how to 1) perform Bartlett’s Test, and 2) Levene’s Test. Both are tests that are testing the assumption of equal variances. Equality of variances (also known as homogeneity of variance, and homoscedasticity) in population samples is assumed in commonly used comparison of means tests, such as Student’s t-test

Here we learn how to do simplify our data preprocessing work using the Python package Pyjanitor. In fact, we are going to learn how to:
> Add a column to a Pandas dataframe
> Remove missing values
> Remove an empty column
> Cleaning up column names
And all of this using only a few lines of code (end of the post).

In this short post, I will show you a quick fix for the error “unsupported operand type(s) for +: ‘float’ and ‘NoneType’” with Pyvttbl. In earlier posts, I have shown how to carry out ANOVA using Pyvttbl (among other packages. See posts 1, 2, 3, and 4 for ANOVA using pyvttbl). However, Pyvttbl is not
