  It convinced people that a strong federal government was needed.

Explanation:

 The Shays´ Rebellion was an armed uprising led by the American Revolutionary War veteran Daniel Shays against the purpose of the Massachusetts government to apply taxes on individuals and their trades.

  It showed the weakness that the Articles of Confederation gave to the central government because it could not afford funding troops to send as help to the State´s militia. Finally, the Rebellion was put down by the army of the State along with privately funded militia.

  It created a sense among the population that the Articles should be revised and reformed. Therefore a Constitutional Convention was created and a new government began.
