Master the essential of hypothesis testing.
Analysis of Variance or ANOVA is a type of significance test in hypothesis testing where we make decisions on population based on the sample data. It is an extension of the t-test. This article covers… Read More »What is the Analysis of Variance (ANOVA) Test
T distribution table is a table that shows the critical values of the t-distribution or critical t score. The critical t-value defines the threshold for significance for the hypothesis test. You can decide to accept… Read More »How to use the t distribution table
Z score table is a standard normal distribution table. It tells us what percentage of values fall below a certain z-score in a normal distribution. We use the z-table to calculate the p-value or critical… Read More »How to use the Z score table?
What is Z Test A z test is a statistical test in hypothesis testing to determine whether two population means are different when the population variance is known and the sample size is large. Z-tests… Read More »Z Test – Formula, Definition, Examples, Types
During hypothesis testing, we need to judge whether we need One Tailed Test or Two Tailed Test to calculate the p-value and critical value. Therefore, we select or reject the null hypothesis based on whether… Read More »One tailed test vs Two tailed test
Paired t-test or Dependent sample t-test is a type of t-test that is used in machine learning for hypothesis testing. This article covers one sample t-test with examples and how we can implement this in… Read More »Paired t-test in hypothesis testing
Independent two sample t-test is a type of t-test that is used in machine learning for hypothesis testing. This article covers one sample t-test with examples and how we can implement this in Python. What… Read More »Independent Two Sample t-test for Hypothesis Testing
Hypothesis testing and confidence Interval are inferential techniques that use an approximation of sample distribution. Confidence intervals use sample data to estimate a population parameter. Whereas, hypothesis testing uses sample data to test a hypothesis.… Read More »Understand Confidence Interval with examples and Python Code
One sample t-test is a type of t-test that is used in machine learning for hypothesis testing. This article covers one sample t-test with examples and how we can implement this in Python. What is… Read More »One Sample T-test for Significance Testing
T-test is a type of significance test in hypothesis testing where we make decisions on population based on the sample data. This article covers different types of t tests, what type of t-test to use,… Read More »Types of T tests in Statistics
