This test is a valuable tool for identifying candidates who possess the skills needed to contribute meaningfully to data-driven decision-making. It helps to gauge theoretical understanding and practical application, saving valuable time in the hiring process.

The questions in the Statistics Test are crafted to evaluate skills across a spectrum of statistical concepts. It assesses the candidate's grasp of basic statistical methods, probabilistic reasoning, and the ability to interpret data. Questions address understanding of different statistical distributions, the formulation and testing of hypotheses, and an aptitude for exploring and summarizing datasets. Skills in probability calculations, inference using confidence intervals, and drawing conclusions from sample data are also evaluated. Further, the test probes understanding of basic regression techniques and their application, as well as familiarity with exploratory data analysis techniques.

Upon completion of the test, you'll receive a detailed scorecard for each candidate. This scorecard provides a clear breakdown of their performance across various statistical skills, allowing you to benchmark candidates and identify top performers for your open positions.

What topics are covered in the Statistics Test?

This Statistics Test is designed to evaluate a candidate's competence across a range of statistical concepts and techniques, key to data-driven decision-making. The assessment begins with Statistics Fundamentals, confirming a solid understanding of basic statistical principles.

It also gauges proficiency in Inference: p-values and confidence intervals, important for interpreting research findings and drawing valid conclusions from data. Strong skills in this area allow candidates to make informed decisions under uncertainty.

Data Sampling is evaluated to determine if candidates understand how to collect representative data, which underpins the validity of subsequent analyses. The test also evaluates Regression, assessing the ability to model relationships between variables for prediction and understanding.

Candidates are tested on Sampling Distributions, important for understanding the behavior of statistics calculated from different samples. Furthermore, the assessment measures Exploratory Data Analysis, confirming skills in summarizing data, identifying patterns, and generating hypotheses. This skill provides a critical first step in any analysis.

The test covers Non-parametric statistics, revealing the candidate's ability to analyze data when standard assumptions are not met. A solid grasp of Probability is assessed, checking ability to quantify uncertainty and make probabilistic predictions. Lastly, the test assesses Data Analysis, confirming competence in transforming, cleaning, and interpreting datasets, which ensures they can extract actionable insights.

How do I interpret test scores?

The primary thing to keep in mind is that an assessment is an elimination tool, not a selection tool. A skills assessment is optimized to help you eliminate candidates who are not technically qualified for the role, it is not optimized to help you find the best candidate for the role. So the ideal way to use an assessment is to decide a threshold score (typically 55%, we help you benchmark) and invite all candidates who score above the threshold for the next rounds of interview.

What experience level can I use this test for?

Each Adaface assessment is customized to your job description/ ideal candidate persona (our subject matter experts will pick the right questions for your assessment from our library of 10000+ questions). This assessment can be customized for any experience level.

Does every candidate get the same questions?

Yes, it makes it much easier for you to compare candidates. Options for MCQ questions and the order of questions are randomized. We have anti-cheating/ proctoring features in place. In our enterprise plan, we also have the option to create multiple versions of the same assessment with questions of similar difficulty levels.

I'm a candidate. Can I try a practice test?

No. Unfortunately, we do not support practice tests at the moment. However, you can use our sample questions for practice.

What is the cost of using this test?

You can check out our pricing plans.

Can I get a free trial?

Yes, you can sign up for free and preview this test.
