z-test: Definition, Assumptions, Advantages, Disadvantages, and Real-Life Example

Definition: The z-test is a statistical hypothesis test used to assess whether the means of two populations are significantly different when the population standard deviation is known. It’s particularly suitable for large sample sizes. The test statistic follows a standard normal distribution (z-distribution), and it’s calculated by comparing the difference between sample means to the […]

t-test – Definition, Assumptions, Advantages, Disadvantages, Application, and Real-life Example

Definition The t-test is a statistical method used to compare the means of two groups and determine if the observed differences between them are statistically significant. It assesses whether the means of the two groups are different enough to conclude that the observed difference is not due to random chance. The t-test is calculated as:

F-test: Definition, Assumptions, Advantages, Disadvantages, Application, and Real-Life Example

Definition The F-test is a statistical test used to compare the variances of two or more samples. It is based on the F-distribution, which arises when the ratio of two independent chi-squared distributions (each divided by its degrees of freedom) follows an F-distribution. The F-test is often used to determine if the variability within groups
