Professional Data Analysis Practice Test

Master the Modern Data Stack: Python, Excel, Power BI, Tableau and R - Interview & Certification Prep

IMPORTANT: This course contains Practice Tests only. It does not contain video tutorials. These tests are designed to assess your Data Analytics skills across the most popular industry tools.

Data is the new currency. But tools are just the means to an end.

In the modern job market, being an "Excel expert" is no longer enough. Companies demand Full-Stack Data Analysts. They want professionals who can clean data in Python, analyze it in SQL/R, and present stunning dashboards in Power BI or Tableau.

Are you ready for your Data Analyst Technical Interview?

Can you write a DAX measure to calculate Year-over-Year growth? Do you know how to handle missing values in a Pandas DataFrame? Can you choose the right chart in Tableau to represent a time series?

Welcome to the MOHNAS Data Analytics Competency Exam.

This course is designed to test your versatility. Whether you are aiming for a Business Intelligence (BI) role, a Data Analyst position, or a specialized certification (like the PL-300), these tests will verify your readiness.

What to expect in this course:
This course consists of 3 Full-Length Practice Tests (60 Questions Total) covering the essential Analyst toolkit.

• Spreadsheets & Statistics. (Advanced Excel, Pivot Tables, VLOOKUP/XLOOKUP, and Descriptive Statistics).

• Programming for Data. (Python, Pandas, R Basics, Data Cleaning, and Manipulation).

• Business Intelligence & Visualization. (Power BI, Tableau, DAX, Power Query, and Dashboard Design).

Topics covered in these questions:

• Excel Mastery: Conditional Formatting, Data Validation, Lookups, and Pivot Charts.

• Python & R: Using pandas for dataframes, matplotlib for plotting, and basic R syntax for statistical analysis.

• Power BI: Understanding the Data Model, Star Schema, Relationships, and writing basic DAX functions (CALCULATE, FILTER).

• Data Process: The ETL Pipeline (Extract, Transform, Load), Data Cleaning, and Handling Null Values.

Why take these Practice Tests?

1. Interview Preparation: Technical screenings for Data Analyst jobs often jump between tools. One minute you are answering an Excel question, the next a Python question. We simulate this environment.

2. Identify Weaknesses: You might be a Tableau wizard but weak in Python. These tests will expose your gaps so you can fix them before applying for jobs.

3. Tool Agnosticism: We teach you to focus on the analysis logic, regardless of which tool is being used.

• Aspiring Data Analysts building their portfolio.

• Excel Users looking to transition into Business Intelligence.
