What are some examples of hypothesis testing?
Hypothesis testing is a statistical method used to make decisions based on data. For example, testing whether a new drug is more effective than an existing one.
Can you give me a specific example with numbers?
Sure! Suppose we want to test if a new teaching method improves student scores. We can set up a null hypothesis that states there is no difference in scores between the two methods.
What would the alternative hypothesis be?
The alternative hypothesis would state that the new teaching method does lead to higher scores than the traditional method.
How do we determine if we reject or fail to reject the null hypothesis?
We use a p-value to determine this. If the p-value is less than our significance level (commonly 0.05), we reject the null hypothesis.
