Unpack the potential biases in a survey about movie-watching habits based on its design and constraints. Learn how limiting to residential phones and specific time frames can affect results. Recommendations are made to ensure a broader, more accurate perspective.
Evaluating Tornado Length Claims: A Statistical Breakdown
Want To Learn More? To watch the entire video and ALL of the videos in the series:
Explore a statistical approach to analyze the claim about average tornado lengths. Understand the nuances of hypothesis testing, from setting null and alternative hypotheses to interpreting P-values. Witness a comprehensive breakdown of the evidence from a sample of 500 tornadoes.
Comparing Stock Returns & Volatility: T-test and F-test Insights
Want To Learn More? To watch the entire video and ALL of the videos in the series:
Compare the mean returns and volatilities of two stocks using t-test and F-test methods. Through the application of hypothesis testing and P-value calculations, we determine which stock provides higher returns and which is riskier.
