Answer 1

1. It is learned that It is easy to interpret the output of independent samples under t-test. The output of t-test is useful to determine how different the mean of one sample is from the mean of another sample.

2. It is also understandable that t-test provides all the necessary information which is needed to know about the population.

3. After exercise, it is learned that t-test leads to good control of the individual differences because only one group is sufficient for testing.

4. But t-test is ineffective in case of multiple comparisons because it results in type I error.

5. It is also learned that realiability of data is another area of concern under t-test.
