Why is the Student t-test good?
Various degrees of freedom for Student’s T. The t test tells you how significant the differences between groups are; In other words it lets you know if those differences (measured in means) could have happened by chance.
How reliable are t-tests?
The T-test appears to be highly reliable and measures a combination of components, including leg speed, leg power, and agility, and may be used to differentiate between those of low and high levels of sports participation.
Does t test compare means?
Essentially, a t-test allows us to compare the average values of the two data sets and determine if they came from the same population.

The independent-samples t test evaluates the difference between the means of two independent. Independence is a methodological concern; it is dealt with (or should be dealt.
What is the assumption of normality in the independent t test?
The test (dependent) variable is normally distributed within each of the two populations (as defined by the grouping variable). This is commonly referred to as the assumption of normality. The variances of the test (dependent) variable in the two populations are equal. This is commonly referred to as the assumption of homogeneity of variance.
