Definition of 'T-Test'

The t-test is a statistical test that is used to determine if there is a significant difference between the mean or average scores of two groups and is commonly used when the variances of two normal distributions are unknown and when an experiment uses a small sample size.

T-Test formula:

Where,

• x₁ is the mean of first data set
• x₂ is the mean of first data set
• S₁² is the standard deviation of first data set
• S₂² is the standard deviation of first data set
• N₁ is the number of elements in the first data set
• N₂ is the number of elements in the first data set
