“Reading Measurement Scales”

MNI = marked number interval AMI = adjacent number interval

MNI = AMI = 1.0 units 0.5 units

MNI = AMI = 10.0 units 1.0 units

MNI = AMI = 10.0 units 2.0 units

MNI = ANI = 10.0 units 5.0 units

MNI = ANI = 50.0 units 10.0 units

“Volumes and Densities”

A 1. Volume = 2. Density = 2 g/cm cm 3

B 3. Volume = 4. Density = 27 cm g/cm 3

C 5. Volume = 6. Density = m kg/m 3

D 7. Volume = 8. Density = cm g/cm 3

E 9. Volume = 10. Density = 144 m kg/m 3

F 11. Volume = 12. Density = 40 cm g/cm 3
