Answer 1

diiferent types of the data

Nominal basically refers to categorically discrete data such as name of your school, type of car you drive or name of a book. This one is easy to remember because nominal sounds like name (they have the same Latin root).

Ordinal refers to quantities that have a natural ordering. The ranking of favorite sports, the order of people's place in a line, the order of runners finishing a race or more often the choice on a rating scale from 1 to 5.

Interval data is like ordinal except we can say the intervals between each value are equally split.

Ratio data is interval data with a natural zero point. For example, time is ratio since 0 time is meaningful.

1) Rating of textbook ( poor fair good excellent)

Here it is Ordinal data becuase it has order but we cannot disgunish them between using a numeric value.

2) The number of ads on a one hour tevevision show:

Here value can be 0,1,2,3,4,..............

And 0 is true zero. zero means absence.

So it is Ratio level

Answer:- Ratio level

25.6−0.05=25.55 Lower boundary

Here it is 25. 5 5& 25.65 are boundaries 25.6
