Data & Analytics

The skills a Data & Analytics assessment can cover, how the assessment runs, and a sample question to try.

Skills covered

Candidates declare the skills they have, and each sitting is generated for their target role and those skills. These are skills from this field that an assessment can cover.

  • SQL
  • Data Modeling
  • Data Cleaning
  • Data Visualization
  • Excel
  • Statistics
  • A/B Testing
  • Business Intelligence
  • Reporting
  • Cohort Analysis

Sample question

After one day and very few visitors, variant B of an A/B test shows a higher conversion rate. What is the best conclusion?

  1. AVariant B is better and should be shipped now
  2. BThe difference may be noise, so keep the test running until the planned sample size is reached
  3. CVariant A is broken and should be removed
  4. DA/B tests cannot measure conversion
Show the answer

B. The difference may be noise, so keep the test running until the planned sample size is reached

With a small sample, random variation can easily produce a gap. Deciding the sample size up front and waiting for it avoids acting on a result that will not hold.

A sample only. Real questions are generated fresh for each sitting, so this exact question will not appear.
