Measurement and Data>Distinguishing Between Situations with and Without Variability in Data(TEKS.Math.6.13.B) Practice Test

Four scenarios are described.

A. Each carton contains exactly 12 identical eggs, counted perfectly by a machine.

B. Times it takes students to run one lap around the track.

C. Every identical box is filled to exactly 500 g with no tolerance by a precise machine.

D. Daily high temperatures in a city during one week.

Which scenarios show data with variability?

Consider these scenarios.

A. Lengths of pencils taken from different boxes.

B. The teacher records a participation score of 10 for every student today.

C. The result of rolling a fair number cube once per student.

D. Every identical can is filled by a machine to exactly 300 g with no tolerance.

Which scenarios would most likely yield no variability?
