It can be used to demonstrate your ability to make data-driven decisions, a crucial skill in many industries.

Hypothesis testing is a fundamental statistical method used to infer the characteristics of a population based on a sample of data. It involves formulating a hypothesis (or assumption), testing it using sample data, and deciding whether to accept or reject the hypothesis. This method is widely used in scientific research, data analysis, business decision-making, and quality control.

The five steps of hypothesis testing are:

1. State the Hypotheses: Formulate the null hypothesis (H₀) and the alternative hypothesis (H₁) based on the research question.
2. Set the Significance Level (α): Decide on the threshold for rejecting the null hypothesis, commonly set at 0.05.
3. Choose the Appropriate Test: Select the statistical test that best fits the data (e.g., t-test, Z-test).
4. Calculate the Test Statistic: Compute the test statistic based on sample data and the chosen test.
5. Make a Decision: Compare the test statistic with the critical value or p-value to determine whether to reject or fail to reject the null hypothesis.

Type 1 and Type 2 errors in hypothesis testing are defined as:

• Type 1 Error (False Positive): Occurs when the null hypothesis is incorrectly rejected, meaning we mistakenly conclude there is an effect or relationship when there is none.
• Type 2 Error (False Negative): Happens when the null hypothesis is not rejected, meaning we fail to detect an effect or relationship that exists.

These errors represent the risks in decision-making, and understanding them is critical for accurate hypothesis testing.

Yes! Hypothesis testing is widely used in data-driven decision-making across various industries, including healthcare, marketing, finance, business analytics, and research. If your job involves analyzing data, making strategic decisions, or interpreting results, this course will equip you with the necessary skills to apply hypothesis testing effectively in your role.

No prior experience is required to take this course. It is designed to be beginner-friendly, starting from the basics and progressively building your understanding of hypothesis testing. Whether you are new to statistics or looking to refresh your knowledge, this course will guide you step-by-step through the core concepts.

You will learn to apply hypothesis testing methods using tools like Python and Excel. These tools will help you perform statistical analyses and implement hypothesis testing techniques in real-world scenarios. The course emphasizes practical applications, ensuring you gain valuable hands-on experience with the tools commonly used in data analysis and decision-making.
