How to be careful before using free statistical help in private companies?

There are a few things to consider when using free statistical help from private companies:

1. Check the company’s reputation: Look for reviews or testimonials from other users to get an idea of the company’s reputation. If the company has a good reputation, it is more likely that the help they provide will be reliable and accurate.
2. Be wary of guarantees: Some companies may make guarantees about the quality of their help. While these guarantees may be tempting, it’s important to be aware that there are no guarantees in statistical analysis. The results of statistical analyses can depend on many factors, and it’s not always possible to predict the outcome with certainty.
3. Understand the limitations of free help: Keep in mind that free statistical help is often limited in scope. It may not be as comprehensive as paid help, and you may not be able to get as much individualized attention.
4. Consider the source of the help: Make sure that the statistical help you are using is coming from a reputable source. If you are unsure about the credibility of a resource, you may want to consult with your instructor or TA before using it.

It’s always a good idea to be cautious when seeking statistical help, especially from private companies. Make sure to do your research and consider all of your options before making a decision.
