How do you determine if the percent growth between two time periods is statistically significant? For example, the total population in 2000 was 180,000. It grew to 220,000 ten years later. How do you determine if this growth was significant? Similarly, group A (6,000 people) earned £50,000 last year. Group B (9,000 people) earned £65,000. Are Group B's earnings over Group A statistically significant?
