Answer 1

Classifies variables into two or more mutually exclusive categories based on a common set of characteristics

Question 2

Ordinal scale

Answer 2

Classifies and ranks variables or score in terms of the degree to which they possess a common characteristic

Question 3

Interval scale

Answer 3

Classifies and ranks variables or scores based on predetermined equal intervals (does not have a true zero)

Question 4

Ratio scale

Answer 4

Classifies and ranks variables or scores based on equal intervals and a true zero point

Question 5

Regression equation

Answer 5

Predicts how much the dependent variable will change given a specific change in the independent variable

Question 6

Null hypothesis

Answer 6

States that no relationship exists between variable

Question 7

Null hypothesis rejected

Answer 7

Significant difference was observed between groups or treatments

Question 8

Null hypothesis accepted

Answer 8

No significant difference was observed between groups or treatments

Question 9

Research hypothesis

Answer 9

Relationship between variables exists and manipulating the independent variable will bring about a change in the dependent variable (may be directional or nondirectional)

Question 10

Face validity

Answer 10

Assumption of validity based on the appearance of an instrument as a reasonable measure of a variable

Question 11

Internal validity

Answer 11

Degree to which the observed differences on the dependent variable are the direct result of manipulation of the independent variable

Question 12

External validity

Answer 12

Degree to which the results are generalizable to individuals or environmental settings outside the experimental study

Question 13

Content validity

Answer 13

Degree to which an instrument measures an intended content area

Question 14

Concurrent validity

Answer 14

Degree to which scores on one test are related to the scores on another criterion test (usually the gold standard)

Sensitivity

Answer 16

Tests ability to identify a true positive

Question 17

Specificity

Answer 17

Tests ability to correctly identify a true negative

Question 18

Predictive value

Answer 18

Tests ability to estimate the likelihood that an individual will test positive or negative for a target condition

Question 19
