scipy chi square goodness of fit
https://youtu.be/Fv-U-pZ4HbI#The Chi-Squared test determines whether there’s a significant association between categorical variables.#It compares the observed frequencies (counts) to the expected frequencies, calculated under the null hypothesis that the variables are independent or that the observed distribution fits a given distribution. #Chi-Squared Goodness-of-Fit Test#This test assesses if the observed frequencies for a single categorical variable match […]

two sample z test scipy
#Example 1 More Manual – From Slides Quicker way to test it – Not Entirely preciseThe ztest function in statsmodels.stats.weightstatsdoes not explicitly allow for directlypassing the population standard deviation. Instead, it estimates the standard error based on thesample standard deviations unless the sample variance is explicitly pooled example 2 marathon times of two running clubs […]

Python One-Sample T-Test
One-Sample T-Test Used to compare the mean of a single sample to a known value (usually a population mean). Example 1 Manual Calculation Step 5: Degrees of freedom and p-value Example 2 – Shoes Two Tail Example 3 – Rookie Batting Average One Tail rookie batting average is the same as the population mean (0.250)Rookie […]
