Many firms that offer statistical help often allow the students to download a sample data analysis. This gives the student a good idea on what type of work the statisticians at the company have done. In most cases, the students simply have to give their name, phone number and their e-mail id to the company, and the sample data analysis will be given to them. The students can then look through the data analysis and judge for themselves as to how good or bad the work is. If they find the work satisfactory, they can hire the services of the firm.
