- When a researcher uses a random sample of 400 to make conclusions about a larger population, this is an example of:
-
- Descriptive statistics
-
- Demographics
-
- Inferential statistics
-
- Dependent variables
- 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.

-
- Interval
-
- Ordinal
-

- 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.
-
- External and internal influences within a study that can affect the validity and reliability of the outcomes.
- External and internal influences within a study that can affect the validity and reliability of outcomes is called:
-
- Continuous variables
-
- Demographics
-
- Bias
-
- Standard deviation
- The subset of the population to be studied is called:
-
- Sample
-
- Variable
-
- Population
- Demographic
