ADVANTAGE
They help a researcher to carry out hundreds or thousands of hypothesis tests in a very short time.
They calculate dozens of regression models in a very short time and then choose the most appropriate one.
In operations research problems, a statistical program is capable of performing thousands of iterations per second of an algorithm in which a person would take several minutes in each one of them.
• They have the ability to choose among thousands of possible outcomes which one of them is optimal.
They allow solving statistical problems applied by brute force or by testing thousands of combinations to finally stay with the one that is believed to be the best for use
DISADVANTAGES
More complex programs require programming skills, as well as more time-consuming calculations.
In statistics, contradictory results can often come out between different tests.
It does not provide the expected results in the expected time.
Sometimes leads to unnecessary sophistication by allowing the use of complex techniques to answer simple questions.
If the user has no previous experience using SPSS or if their statistical knowledge is not up to date, it is difficult to understand which options to select.
Results reports contain an excessive level of information.
