✔️ [Comp] Analytical Aptitude Flashcards
Delphi technique
Technique that progressively collects information from a group of anonymous respondents.
- This technique progressively collects information from a group on a preselected issue. The first respondent proposes information, the next respondent adds something different, and so on, until a list can be compiled. The respondents are anonymous. In the second round, the researcher circulates the list and asks each respondent in turn to refine previous ideas, to comment on each idea’s strengths and weaknesses for addressing the issue, and to identify new ideas.
- This technique is designed to facilitate group involvement, problem solving, and individual thinking while avoiding “group think,” where participants can be influenced by what others say.
Statistical method used to determine whether a relationship exists between variables and the strength of the relationship.
Regression 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.
Trend Analysis
Compares the relative size of two variables and yields a percentage
- Ex: turnover rate
Comparing the sizes of two variables to produce an index or percentage; commonly used to analyze financial statements.
Ratio Analysis
Type of analysis that starts with a result and then works backward to identify fundamental cause.
Root-Cause Analysis:
Distance of any data point from the center of a distribution when data is distributed in a “normal” or expected pattern.
Standard Deviation
Data Cleansing:
- AKA “data wrangling”—a process by which incomplete sets, anomalies, errors, and gaps in the data are identified and addressed.
- Cleansing data is connected to validation and identifying bias, as these processes assess how useful and correct the data is. By cleansing the data collected, you can ensure that decisions are made based on better-quality data.
Reflects the ability of a data-gathering instrument or tool, such as a survey or a rater’s observation or physical measurement, to provide results that are consistent
Extent to which a measurement instrument provides consistent results.
Reliability
Extent to which a measurement instrument measures what it is intended to measure.
- answers: what does this instrument measure? how well does the instrument measure it?
- Validity reflects the degree to which a tool measures attributes that are relevant to the measurement’s intention.
Validity
Statistical Sampling
- Sampling is often used when the population to be analyzed is very large or when data cannot be obtained from the entire population.
- The sample must be representative; it must accurately reflect the key characteristics of the entire population being studied.
- For example, the sample used in a wage survey of employees in a certain job should include the same ratio of genders and years of experience as for all employees in that job.
Being able to apply the results of data gathering and analysis to make better busniess decisions
Evidence-based decision making EBDM
examining an idea, a process, or an event with an open, objective, and inquiring mind. It’s a critical skill in EBDM using sound data to hypothesize, assess, and select solutions. refers to

EBDM
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
Objective measurements that can be verified and used in statistical analysis.
Quantitative data
Data-sorting technique in which group members add related ideas and indicate logical connections, eventually grouping similar ideas.
