It is used when you want to test if the mean of the population from which the sample is drawn is of a hypothesized value. The ‘One sample T Test’ is one of the 3 types of T Tests.

Get FREE pass to my next webinar where I teach how to approach a real ‘Netflix’ business problem, and how to transition to a successful data science career. You sample 10 cars from the dealership, measure their mileage and use the T-test to determine if the manufacturer’s claim is true.īy end of this, you will know when and how to do the T-Test, the concept, math, how to set the null and alternate hypothesis, how to use the T-tables, how to understand the one-tailed and two-tailed T-Test and see how to implement in R and Python using a practical example.
If it is found from the test that the means are statistically different, we infer that the sample is unlikely to have come from the population.įor example: If you want to test a car manufacturer’s claim that their cars give a highway mileage of 20kmpl on an average. One sample T-Test tests if the given sample of observations could have been generated from a population with a specified mean.
