An integer is like a whole number (28 is an integer).
Irrational means the decimal goes on forever.......and cannot be written as a fraction (0.9857... is irrational).
A number that is not real is the squareroot of a negative, or something times i, or dividing by zero (5/0 is unreal).
A rational number can be written as a fraction (like 8 and 1/7).

Volgvan

Answer:

a) Participants in Tai Chi course

b) Nominal

c) Magnitude of arthritis pain

d) Ordinal

Step-by-step explanation:

TYPES OF VARIABLES:

  • Independent Variable:

An independent variable is the one controlled or changed in an experiment to test the effects on the dependent variable. If this variable is changed, there shall be effects on the experiment.

In this case, number of participants in the course was independent.

  • Dependent Variable:

Dependent variable is the one being tested and measured. If the independent variable changes, this variable will show the effect of the changes.

<em>The variables can be determined by their cause and effect on the experiment.</em>

TYPES OF SCALES:

<em>There are two variations in types of scales; Quantitative and Qualitative.</em>

<em>Qualitative variables are measured by either nominal or ordinal scale, while quantitative variables are measured by ratio or interval.</em>

  • Nominal scale:

Nominal scales assign identifiers as labels to objects or classes of objects. The  assigned numbers carry no additional meaning except as identifiers for example: patient A, patient B etc.  

  • Ordinal scale:

Ordinal scales assign numbers to objects to rank  an attribute. For example: Level of pain 1 - 10, Level of satisfaction etc.

  • Interval:

In an interval scale, numbers are  assigned to objects such that the interval helps in interpretation of the variables. For example: age of patients: 30 - 40, 40 - 50 etc.

  • Ratio:

Ratio scales includes an absolute “zero” point. For example, Rate of arthritis in patients of a particular age etc.
