What is hypothesis testing?
An example of an AI chatbot conversation about hypothesis testing and its applications.
What is hypothesis testing?
Hypothesis testing is a statistical method used to make decisions based on data. It involves formulating a null hypothesis and an alternative hypothesis.
Can you give me an example of a hypothesis test?
Sure! For instance, if a company claims that their light bulbs last 1000 hours, you could test this by sampling a few bulbs and checking their average lifespan.
How do you determine if the results are statistically significant?
You typically use a p-value to determine significance. If the p-value is less than a predetermined threshold (like 0.05), you reject the null hypothesis.
What are some common types of hypothesis tests?
Common types include t-tests, chi-square tests, and ANOVA, each suited for different types of data and research questions.
