Answer 13

Interval Ratio

Question 14

level of measurement in which data is classified into mutually exclusive categories

Answer 14

Nominal

Question 15

level of measurement in which data is classified into mutually exclusive categories however, ranking or ordering is imposed on categories

Answer 15

Ordinal

Question 16

level of measurement in which data is classified into categories with ranking and are mutually exclusive as in ordinal level of measurement but additionally, specific meanings are applied to the distances between categories- distances are assumed to be equal and can be measured

Answer 16

Interval

Question 17

Which level of measurement lacks an absolute zero point?

Answer 17

Interval

Question 18

level of measurement that is interval measurement with the addition of a meaningful zero

Answer 18

Ratio

Question 19

statistics that summarize the data from a sample, instrument, or scale such as tendency or variation

Answer 19

Descriptive Statistics

Question 20

statistics that allow a researcher to generalize about a population based on the results from the sample

Answer 20

Inferential Statistics

Question 21

variables that may influence the relationship between the variables in the study or could compete with the independent variable in explaining the outcome

Answer 21

Confounding Variable (aka Intervening, Extraneous, Controlled, Hidden)

Question 22

extent to which assessments are consistent

Answer 22

Reliability

Question 23

refers to how well a test measures what it intends to measure

Answer 23

Validity

Question 24

a variable that takes on one of only two possible values when observed or measured. The value is most often a representation for a measured variable (e.g., age: under 65/65 and over) or an attribute (e.g., gender: male/female).

Answer 24

Dichotomous Variable

Question 25

a variable that can be counted and has a finite and fixed number of possible values (i.e. every value is assigned to a particular group or category...variables measured at the nominal and ordinal level

Answer 25

Categorical Variable

Question 26

variables that have every possible value on a continuum

Answer 26

Continuous Variable

Question 27

variables that have values that are countable but do not include numeric values between countable categories

Answer 27

Discrete Variable
