These are three sample questions from Bryq’s Analytical Skills assessment, a test for hiring data analysts and other roles that rely on data-driven decisions. The full assessment covers three levels: beginner, intermediate, and advanced, from basic statistics to advanced analytical methods. Each question is multiple choice, with one correct answer out of four options.
Beginner
Question
In data analysis, what does the term “mean” refer to?
Select your answer
The sum of all values divided by the number of values.
The difference between the highest and lowest values.
The middle value in a dataset.
The most frequently occurring value.
WHY IS THIS THE CORECT ANSWER
The mean is the arithmetic average: total the values and divide by how many there are. The other options describe the median, mode and range.
Intermediate
Question
Which problem-solving tool is best suited for visually mapping the relationship between a problem and its potential causes?
Select your answer
Fishbone (Ishikawa) diagram.
Scatter plot.
Decision matrix.
Gantt chart.
WHY IS THIS THE CORECT ANSWER
A fishbone diagram arranges potential causes into categories branching from a central problem, making it a structured root-cause tool.

Select your answer
Monte Carlo simulation.
Pareto analysis.
Six Sigma methodology.
Linear regression modelling.
