Activity 3.2 – Resources for Engineering.

Question: Look at the following examples of a data sheet for a particular model of washing machine. Pick out two examples of quantitative data and two examples of qualitative data about the machine.

 

Quantitative.

  •       “Energy consumption 135kw h/annum, based on 220 standard washing cycles for cotton programmes at 60c and 40c at full and partial load, and the consumption of the low-power modes. Actual energy consumption will depend on how the appliance is used.”
  •       “Water consumption 9460 1/annum, based on 220 standard washing cycles for cotton programs at 60c and 40c at full and partial load. Actual water consumption will depend on how the appliance is used.”

 

Qualitative.

  •        “Free-standing”
  •        “Trade Mark – Bosch.”

Quantitative – Information involves numbers and deals with the numerical measurements of something.

Qualitative – information refers to the nature of something, may be more subjective for example “If your pet cat is black and has mass 4.1kg then the colour , black is a qualitative description while the mass 4.1kg, gives a quantitative measurement.

Data – Is a collection of information on a particular topic which may be quantitative or qualitative. – For Engineering purposes you are usually most interested in technical data, much of which is quantitative.
