IIBA CBDA Exam - Topic 4 Question 16 Discussion

Actual exam question for IIBA's CBDA exam

Question #: 16
Topic #: 4

A job satisfaction study is being considered. Half of the employees of the company will be interviewed by senior managers and the other half of the employees will be interviewed by an external market research company, using the same set of questions. Which of the following might be a concern for using this approach to collect study data?

AReliability

BValidity

CTimeliness

DPrecision
Explanation:
Reliability is the degree to which a data collection method produces consistent results under the same conditions1. In this case, the reliability of the study data might be compromised by the different interviewers (senior managers vs. external market research company), who might have different biases, expectations, or rapport with the employees. This could affect how the employees respond to the same set of questions, and thus introduce variability in the dat
a.Validity, timeliness, and precision are not directly affected by the choice of interviewers, as they depend more on the quality, relevance, and accuracy of the questions and the data analysis.

Show Suggested Answer

Suggested Answer: A

Summary statistics are numerical measures that describe certain characteristics of a data set, such as the mean, median, mode, standard deviation, range, or quartiles. Summary statistics can help simplify and communicate complex data, but they can also obscure or distort important information, such as the distribution, shape, outliers, or trends of the data. Contextualization is the process of providing relevant background information, assumptions, limitations, or explanations for the data analysis and its results. Contextualization can help avoid misinterpretation, confusion, or bias when using summary statistics. Contextualization can also help connect the data analysis to the business problem, objectives, and stakeholders.

I wonder if timeliness could be a factor too, but it seems like the main issue would be the reliability of the data collected by different interviewers.

This reminds me of a practice question we did about bias in surveys. I think reliability is definitely the main concern in this scenario.

I'm not entirely sure, but I think validity might also be an issue since the context of the interviewers could affect how employees feel about their answers.

Reliability is the way to go on this one. I'll explain how the senior managers and external researchers might have different biases that could affect how the employees answer the questions.

While the other options are important, reliability is the clear winner here. This approach sounds like a recipe for a data smoothie, with each interviewer adding their own 'special' ingredient.
