I think the program is very useful and convenient. It doesn't need program installment and on some pages, I could finish my assignment. With some mouse click, the program gives me various charts and graphs for me to understand data visually. Number Analytics, also, offers intelligent functions. When I want to find out a relationship in each data or compare each data, the program recommends statistical methods like T-test or Anova test. I'm a statistic major student. During searching for a data software program, I entered the site by chance. However, I still use the software program even after a free trial. If you do not pick a data software program, I confidently recommend the program.
