Critical Evaluation Flashcards
Extent to which a measurement instrument provides consistent results.
Reliability
Average of data that adds factors to reflect the importance of different values.
Weighted mean
Raw average of data that gives equal weight to all values, with no regard for other factors.
Unweighted mean
Comparing the sizes of two variables to produce an index or percentage; commonly used to analyze financial statements.
Ratio analysis
Small group of invited persons (typically six to twelve) who actively participate in a structured discussion, led by a facilitator, for the purpose of eliciting their input.
Focus group
Type of analysis that starts with a result and then works backward to identify fundamental cause.
Root-cause analysis
Statistical method used to test the possible effects of altering the details of a strategy to see if the likely outcome can be improved.
Scenario/what-if analysis
Data-sorting technique in which a group categorizes and subcategorizes data until relationships are clearly drawn.
Affinity diagramming
Trend analysis
Statistical method that examines data from different points in time to determine if a variance is an isolated event or if it is part of a longer trend.
Statistical method used to determine whether a relationship exists between variables and the strength of the relationship.
Regression analysis
Data-sorting technique in which group members add related ideas and indicate logical connections, eventually grouping similar ideas.
Mind mapping
Technique that progressively collects information from a group of anonymous respondents.
Delphi technique
Statistical method for identifying the degree of difference between planned and actual performance or outcomes.
Variance analysis
Extent to which a measurement instrument measures what it is intended to measure.
Validity
Distance of any data point from the center of a distribution when data is distributed in a “normal” or expected pattern.
Standard deviation
