Which of the following statements are true related with GIS?
Natural phenomena are usually fields
Man-made phenomena are usually objects
Both ‘1’ & ‘2’ are true
None of the above
Which of the following is true about ‘Nominal Data Values’
They are values that provide a name or identifier so that we can discriminate between different values
True computations cannot be done with these values
When the values assigned are sorted according to some set of non-overlapping categories, they are called ‘categorical data’
All of the above
Which of the following is true about ‘Ordinal Data Values’
They are date values that can be put in some natural sequence but that do not allow any other type of computation
An example of Ordinal data value is classifying household income as ‘low’, ‘average’ or ‘high’
None of the above
Both ‘1’ & ‘2’
Which of the following is true about ‘ Ratio Data Values’
They allow most, if not all, forms of arithmetic computation

They have a natural zero value
Continuous fields can have ratio data values
All of the above
