ACI2604 Assignment 2 Solutions 2026
UNISA
Due Date: 12 June 2026
, QUESTION 1: MEASURABLE ATTRIBUTES OF PHENOMENA
Selected Object:
Classroom Chair
Measurable Appropriate measuring Suitable unit of
attribute instrument measurement
Length Measuring tape Centimetres (cm)
Mass Bathroom scale or balance Kilograms (kg)
Temperature Thermometer Degrees Celsius (°C)
Width Measuring tape or ruler Centimetres (cm)
Explanation
A numerical value must always be written together with a unit of measurement because
the unit explains the type and size of the measurement. Without a unit, the number
becomes meaningless and can easily cause confusion. For example, if a learner says
the chair measures “80”, it is not clear whether the measurement is in centimetres,
millimetres or metres. Units make communication accurate and help people compare
measurements properly. Standard units are also important because they ensure that
measurements are consistent and understood in the same way by everyone.
