Maria wants to know the average arrival time
of the students at her school. She arrives one
morning at 8:30 a.m. and records the arrival
times of the students that arrive between
8:30 a.m. and 9:00 a.m. Explain why Maria's
sample is not a representative sample.

  • Maria arrived at 8:30
  • It's can't be told that no one have arrived before her
  • She registered the times between 8:30 to 9:30 .
  • She hasn't registered the data of students who came before her .
  • So it's not a representative sample
