Join Carlos, a Warwick undergraduate student, on a deep dive into a simple yet effective approach to hypothesis testing using Wolfram Mathematica. From everyday claims like marriage affecting wages to the intricacies of correlation versus causation, embark on a statistical adventure that merges intuition with rigorous analysis. Watch a real-life hypothesis testing problem be solved using an interactive graphical model coded with the Wolfram Language’s Manipulate function.
This video explains the 5 steps for hypothesis testing, which are:
(1) state the null hypothesis and alternative hypothesis
(2) set the significance level
(3) calculate the test statistic from the data
(4) find the critical value from the degrees of freedom and significance level
(5) make a decision: either reject the null hypothesis or do not reject the null hypothesis
Start your journey in coding your way through basic statistics with this introductory video.
