<u>Positive Economists'</u> purpose is to create an explanation of a certain economic phenomena.
These economists use statistics in order to find out the aggregate behavior of the people because of a certain economic decisions. From this, they can developed an understanding to explain the economic phenomena.
<u>The normative economists' </u>purpose is to find out whether a certain economic decision achieve its original purpose.
They used statistic as a quantitative measurements. They determine the goals of a certain economic policy and They compared the statistic before the economic policy was implemented to the condition after the implementation .
This will help them know whether the policy achieve its original goals.
