What is hypothesis testing?
An example of an AI chatbot conversation about hypothesis testing in statistics.
Can you explain what hypothesis testing is?
Sure! Hypothesis testing is a statistical method used to make decisions based on data. It involves formulating a null hypothesis and an alternative hypothesis.
What are the steps involved in hypothesis testing?
The main steps are: 1) State the hypotheses, 2) Choose a significance level, 3) Collect data, 4) Calculate the test statistic, and 5) Make a decision based on the p-value.
What is a null hypothesis?
The null hypothesis is a statement that there is no effect or no difference, and it serves as the default assumption in hypothesis testing.
Can you give me an example of hypothesis testing?
Certainly! For instance, if you want to test if a new drug is more effective than an existing one, your null hypothesis might state that there is no difference in effectiveness.
