Hypothesis testing is a formal procedure for investigating our ideas about the world using statistics . It is most often used by scientists to test specific predictions, called hypotheses, that arise from theories. There are 5 main steps in hypothesis testing: State your research hypothesis as a null hypothesis and alternate hypothesis (H o ) and (H a or H 1 ). Collect data in a way designed to test the hypothesis. Perform an appropriate statistical test . Decide whether to reject or fail to reject your null hypothesis. Present the findings in your results and discussion section. Though the specific details might vary, the procedure you will use when testing a hypothesis will always follow some version of these steps.

The alternate hypothesis is usually your initial hypothesis that predicts a relationship between variables. The null hypothesis is a prediction of no relationship between the variables you are interested in.  H 0 : Men are, on average, not taller than women. H a : Men are, on average, taller than women.

Test strategies outline the overall approach to testing, including the scope, objectives, resources, and timelines. They provide a high-level view of how testing will be conducted to achieve desired outcomes. 🎯 On the other hand, test plans are detailed documents that define the specific tests to be conducted, the test environment setup, the test cases, and any risks or issues that need to be addressed during testing. 📝 Constantly Facing Software Glitches and Unexpected Downtime? Discover seamless functionality with our specialized testing services. 📌 Test Strategy Overview: A test strategy guides testing with methodologies and best practices, considering project goals and risks. 📌 Key Elements: It includes testing objectives, scope, approach, environment, defect management, automation, risk assessment, and reporting. 📌 Influencing Factors: Project requirements, methodology, technical setup, and organizational culture shape the test strategy. 📌 Benefits: Alignment with goals, structured testing, enhanced coverage, early defect detection, and resolution. 📌 Strategy vs. Plan: The strategy guides, while the plan details specific testing activities. 📌 Best Practices: Define objectives clearly, tailor to project needs, align with standards, involve stakeholders, and update regularly. What is a Test Plan? A test plan serves as a detailed roadmap outlining the approach, scope, and objectives of software testing . It defines the scope of testing, including various aspects such as performance testing , security testing , and regression testing. The testing team, comprising developers and testers, collaborates on a robust test plan meeting project specs and quality standards. This includes aspects of the testing strategy like unit, integration, manual, and load testing ⚙️ for thorough coverage and effective execution.

A t test is a statistical test that is used to compare the means of two groups. It is often used in hypothesis testing to determine whether a process or treatment actually has an effect on the population of interest, or whether two groups are different from one another.  The null hypothesis ( H 0 ) is that the true difference between these group means is zero. The alternate hypothesis ( H a ) is that the true difference is different from zero.

If you want to compare more than two groups, or if you want to do multiple pairwise comparisons, use an ANOVA test or a post-hoc test. The t test is a parametric test of difference, meaning that it makes the same assumptions about your data as other parametric tests. The t test assumes your data: are independent are (approximately) normally distributed have a similar amount of variance within each group being compared (a.k.a. homogeneity of variance) If your data do not fit these assumptions, you can try a nonparametric alternative to the t test, such as the Wilcoxon Signed-Rank test for data with unequal variances .

Statistical tests work by calculating a test statistic – a number that describes how much the relationship between variables in your test differs from the null hypothesis of no relationship. It then calculates a p value (probability value). The p -value estimates how likely it is that you would see the difference described by the test statistic if the null hypothesis of no relationship were true.
