Understand the concept of hypothesis testing: Hypothesis testing is a statistical method used to determine whether there is enough evidence to support a specific claim or assumption about a population parameter, such as financial ratios.
Recognize the purpose in financial analysis: Financial analysts use hypothesis testing to assess whether observed differences in financial ratios between companies or over time are statistically significant, meaning they are unlikely to have occurred due to random chance.
Formulate hypotheses: Analysts typically set up a null hypothesis (H₀), which assumes no significant difference in the financial ratios, and an alternative hypothesis (H₁), which suggests there is a significant difference.
Perform statistical tests: Analysts collect data on financial ratios and apply appropriate statistical tests, such as t-tests or ANOVA, to evaluate the hypotheses. These tests help determine whether the null hypothesis can be rejected based on the data.
Interpret results: Based on the p-value or test statistic obtained, analysts decide whether the observed differences in financial ratios are statistically significant. This helps them make informed decisions about the financial health or performance of companies.
