Some Details Of Data

Dear Collegues AoA!

As You Know that all of us are presently dealing with data, in one or other form.
For meaningful operation at the four levels of measurement, we must understand
that some data can only be catgorized but cannot be ordered, while other data can be categorized as well as oredered,Still there are some data which can be categorized, ordered and also subtracted.
There is another fourth type of data which in addition to the above levels of measurement can also be shown as multiple of another data

For Example

Level of measurement	Put data in categories	Arrange data in order	Subtract data value	Determine if one data is a multiple of another
Nominal	Yes	No	No	No
Ordinal	Yes	Yes	No	No
Interval	Yes	Yes	Yes	No
Ratio	Yes	Yes	Yes	Yes

	Example of data set	Meaningful Calculations
Nominal Level (Qualitative data)	Major PGA Tournaments The masters The US Open The British open Major PGA Championship	Put in category. For example there are four Categories of major PGA Tournaments.
Ordinal Level (Qualitative or Quantitative data)	Motion Picture Association of America Rating Description G General Audience PG Parents Guidance Suggested PG-13 Parents strongly Cautioned R Restricted NC-17 17 & Under not Permitted	Put in Categories and put in Order For instance a PG Rating Has A Stronger Restriction than G Rating
Interval Level (Quantitative data)	Average Monthly Temperature (F) For Karachi January 20 Feb 25 March 30 April 35 May 40	Put in categories put in order and find the differences in values For instance 25-20= 5 which means that February was 5 degrees warmer than January
Ratio Level (Quantitative data)	Average monthly Raining of Karachi(in inches) Jan 0.3 Feb 3.9 March 4 April 5 May 6 inches	Put in categories put in order, find differences and find Ratios For instance 6/4 = 1.5 which means that there was 1.5 times more rain in May than in March
