What is t-test?

Accepted Answer

t-test is a statistical test used to determine if there is a significant difference between the means of two groups.

It compares the means of two groups and assesses if the difference is statistically significant.
It is commonly used in hypothesis testing and comparing the effectiveness of different treatments or interventions.
There are different types of t-tests, such as independent samples t-test and paired samples t-test.
The t-test calculates a t-value and p-value, where the p-value indicates the probability of obtaining the observed difference by chance.
If the p-value is below a predetermined significance level (e.g., 0.05), the difference is considered statistically significant.
