Google Analytics Google Analytics Individual Qualification (IQ) Free Practice Test — 30 Questions
This practice bank exercises knowledge of GA4's data processing under consent, cross-device tracking, and session attribution. It tests decisions about diagnosing conversion declines, interpreting sampled data, and applying behavioral competencies like adaptability and problem-solving. Mastery requires understanding how consent affects data collection, how User-ID enables cross-device unification, and how to use reports like user flow and conversion funnels to identify friction points.

Data Privacy and Consent in GA4
Consent management directly impacts data collection. When a user declines cookies, no analytics data is recorded for that session. Subsequent acceptance creates a new session, and prior interactions are lost. Understanding this is crucial for accurate attribution and interpreting reported metrics. The practice bank tests this through scenarios where users deny then grant consent, requiring analysts to recognize that only post-consent activity is captured.
- Declining consent means no session data is recorded.
- Granting consent later starts a new, separate user session.
- Attribution models cannot credit pre-consent interactions if data was never collected.
Cross-Device and User Identification
GA4's User-ID feature allows associating authenticated sessions across multiple devices into a single user profile. Without it, each device is tracked as a separate user. The practice bank includes scenarios where a user visits on mobile then desktop after logging in; the correct answer emphasizes implementing User-ID to unify the journey. This enables accurate cross-device attribution and a complete view of the customer path.
- User-ID links sessions across devices for logged-in users.
- Client-ID is device-specific and cannot cross devices.
- Cross-device attribution requires User-ID or Google signals.
Behavioral Competencies in Analytics
Several questions assess adaptability, problem-solving, and data analysis capabilities when facing declining performance. The correct answers emphasize systematic investigation (e.g., analyzing user flow, segmentation, A/B testing) rather than reactive actions like increasing ad spend. The practice bank validates that analysts should pivot strategies based on data insights, diagnose root causes through funnel analysis, and avoid jumping to conclusions.
- Adaptability: quickly pivot strategies when data suggests a new approach.
- Problem-solving: systematically identify root causes using GA reports.
- Data interpretation: distinguish between metric fluctuations and genuine issues.
Data Sampling and Attribution Models
GA4 may sample data when queries are complex or high-volume, leading to estimated results. The practice bank includes a question about custom report sampling vs. 100% data in standard reports. Additionally, attribution models (e.g., last-click vs. position-based) affect how credit is assigned to touchpoints. Questions test the ability to choose the right model for understanding early-funnel contributions and to recognize when sampled data might mislead conclusions.
- Sampling occurs when query complexity exceeds processing limits; indicated by sampling rate.
- Position-based attribution gives 40% credit each to first and last touch, 20% to middle.
- Last-click model undervalues early interactions like social media exposure.

Consider a scenario where a potential client visits an e-commerce website for the first time, browses several product pages, but declines the cookie consent banner for analytics and advertising. Subsequently, the same user returns to the website a week later, this time accepting all cookies. During this second visit, they add an item to their cart and complete a purchase. According to Google Analytics 4\'s data processing and attribution principles, which session would typically receive credit for the conversion if the website\'s primary attribution model is set to \"Data-driven attribution\"?
Study workflow
Turn one IQ attempt into a study plan
- 1
Audit Consent Implementation
Verify that your consent management platform (CMP) correctly blocks GA4 tags before consent and fires them after. Use Google Tag Assistant to confirm tag behavior. This ensures you understand which sessions are recorded and avoid misattributing conversions.
- 2
Set Up User-ID for Cross-Device Tracking
Implement User-ID by sending a unique, persistent ID when users log in. Configure the User-ID view in GA4 to unify sessions across devices. This enables accurate cross-device attribution and user-centric reporting.
- 3
Analyze Conversion Funnels with Path Exploration
In GA4, use the Path Exploration technique to visualize user journeys. Add events like 'add_to_cart' and 'purchase' as steps. Identify where drop-offs occur and segment by traffic source, device, or consent status to diagnose issues.
- 4
Compare Attribution Models in Model Comparison
Use the Model Comparison tool in GA4's Advertising workspace. Select models like last-click, position-based, and data-driven. Compare how conversion credit shifts across channels to inform budget allocation and campaign optimization.
- 5
Detect and Validate Data Sampling
When running custom reports, check for a sampling indicator (e.g., 'based on X% of sessions'). To reduce sampling, narrow the date range, use fewer dimensions, or export data to BigQuery. Always verify critical findings with unsampled reports.
FAQ
Questions about this IQ practice page
Clear boundaries on what the bank covers, how to use it, and where official vendor information still matters.
What happens to GA4 data when a user declines consent?+
No data is collected for that session. GA4 tags do not fire. If the user later accepts consent, a new session starts with data recorded from that point. Previous interactions are lost.
How does User-ID improve cross-device tracking?+
User-ID associates sessions from different devices to the same authenticated user, enabling a unified view of the customer journey. Without it, each device is treated as a separate user.
What is data sampling in GA4 and when does it occur?+
Data sampling occurs when a query exceeds processing limits. GA4 uses a subset of sessions to estimate results, indicated by a sampling percentage. It can affect accuracy for complex or high-traffic queries.
Why might conversion rates drop even if traffic is stable?+
Possible causes include landing page UX issues, checkout friction, or targeting mismatch. Use user flow and funnel analysis to identify drop-off points, and consider segmentation by device or source.
Which attribution model gives credit to early touchpoints?+
Position-based (40% to first and last touch) and linear (equal credit) models value early interactions. Last-click only credits the final touchpoint, undervaluing awareness-stage channels.
