One Sample t-Test

Explore how to conduct a one sample t-test to determine if a sample mean differs significantly from a population mean. Learn to use Python's scipy.stats module with real data, interpret p-values, and make decisions about null hypotheses under a 95% confidence level.

We'll cover the following...

One-sample t-test

A One sample t-test checks whether a population mean differs from the sample mean or not. We can use the function ttest_1samp from the scipy.stats module.

We will be using the Student Alcohol Consumption Dataset. We will take a sample from the data and find the mean grade. We will check if the population mean grade (μ\mu) differs from the sample mean grade (xˉ\bar{x}) or not.
