Question 2

Answer 2

Time-series

Quasi experimental design

Question 3

Answer 3

Internal validity

Question 4

Ability to measure phenomenon it intends to measure

Answer 4

Relevance or validity

Question 5

Test whether or not a generalization can be made from the study to a larger population

Answer 5

External validity

Question 6

ANOVA; Tool used to evaluate validity
Answers the question are there one or more significant differences anywhere among the samples. Used when several products compete against one another

Answer 6

Analysis of variance

Question 7

Consistency or reproducibility of test results

Answer 7

Reliability

Question 8

Amount of variation that occurs randomly. Less random variation results in greater precision in the measurement and greater reliability

Answer 8

Precision

Answer 25

Inferential statistics

Question 26

Test whether or not there is a real difference between categories; used with attributes that have more than two categories; compares the frequency with which we’d expect certain observations to occur with the frequency that actually occurred

Answer 26
