one that affects, or influences

another variable

Answer 22

Question 24

determines the
algebraic operations that can be performed and the statistical
tool to be used in such data.

Answer 24

The level of measurement

Question 25

is used when we want to distinguish one

object from another for identification purposes

Answer 25

nominal scale

Question 26

We can only
say that one object is different from another, but the amount if
difference cannot be determined

Answer 26

nominal scale

Question 27

examples of nominal level of measurement

Answer 27

Gender, Nationality, Civil Status

Question 28

If the categories can be put in order, the scale is called an

Answer 28

ordinal scale.

Question 29

If the categories of a qualitative variable are unordered, then
the qualitative variable is said to be defined on a

In the _____ level, data are arranged in some specific

order or rank.

Answer 30

ordinal

Question 31

When objects are measured in this level, we

Answer 31

ordinal

Question 32

examples of ordinal

Answer 32

Ranking of contestants in a beauty contest, of

siblings in a family, of honor students

Question 33

If one can compare the differences between
measurements of the variable meaningfully, but not the
ratio of the measurements, then the quantitative variable is
defined on

not only one is greater or less than the other, but can
also specify the amount or difference,

Answer 34

interval

Question 35

If one can compare both the
differences between measurements of the variable and the
ratio of the measurements meaningfully, then the
quantitative variable is defined on
