If a study is comparing number of falls by age, age is considered what type of variable?

Interval

Ordinal

Ratio

Nominal Validity is:

A data item, such as characteristics, numbers, properties, or quantities, that can be measured or counted.

The extent to which an idea or measurement is well-founded and an accurate representation of the real world.

A measurement level with equal distances between the points and a zero-starting point.

Raw unorganized information from which conclusions can be made.

Descriptive statistics

Demographics

Inferential statistics

Dependent variables

A variable is considered:

A data item, such as characteristics, numbers, properties, or quantities, that can be measured or counted.

A component of mathematics that looks at gathered data.

Statistics designed to allow the researcher to infer characteristics regarding a population from sample population.
