CTC Data Analysis & Reporting 3

Question 1

A root cause analysis on escaped defects reveals 60% originated during requirements phase. Which action best addresses this finding?

Accepted Answer

Strengthen requirements review and static testing early in the lifecycle

Answer

Since the defects originate in requirements, the highest leverage is shifting quality activities left to catch issues at that phase.

Question 2

In IEEE 829-style test reporting, which document provides the formal record of test execution results for individual test cases?

Accepted Answer

Test log

Answer

The test log (or test execution log) chronologically records each test case run, its outcome, and any anomalies observed during execution.

Question 3

A data analyst computes the correlation coefficient between test execution hours and defects found as r = 0.08. What does this indicate?

Accepted Answer

Virtually no linear relationship between hours spent and defects found

Answer

An r value near zero indicates negligible linear correlation, meaning effort hours alone do not predict defect discovery in this dataset.

Question 4

Which visualization is most effective for comparing defect counts across five different product modules simultaneously?

Accepted Answer

Clustered bar chart

Answer

A clustered bar chart allows direct side-by-side magnitude comparison across multiple discrete categories such as modules.

Question 5

A test conductor must report test progress to both technical leads and executive sponsors. What is the best practice?

Accepted Answer

Create two reports: a detailed technical report and a high-level executive dashboard

Answer

Tailoring reporting depth and terminology to each audience ensures the information is actionable and appropriate for their decision-making needs.
