Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment Statistics Test in your hiring process is that it is an elimination tool, not a selection tool. In other words: you want to use the test to eliminate the candidates who do poorly on the test, not to select the candidates who come out at the top. While they are super valuable, pre-employment tests do not paint the entire picture of a candidate’s abilities, knowledge, and motivations. Multiple easy questions are more predictive of a candidate's ability than fewer hard questions. Harder questions are often "trick" based questions, which do not provide any meaningful signal about the candidate's skillset.

What topics are covered in the Statistics Test?

  • Statistics Fundamentals

    Statistics Fundamentals involves the basic concepts and principles of statistics, such as measures of central tendency, measures of variability, and probability theory. This skill is measured in the test to assess a candidate's understanding of the foundational concepts required for further statistical analysis.

  • Inference: p-values and confidence intervals

    Inference: p-values and confidence intervals focus on statistical inference, which involves making conclusions or predictions about a population based on sample data. This skill is measured in the test to evaluate a candidate's ability to perform hypothesis testing and determine the significance or confidence level of statistical results.

  • Data Sampling

    Data Sampling refers to the process of selecting a subset of observations from a larger population for statistical analysis. This skill is measured in the test to gauge a candidate's knowledge of different sampling techniques, understanding of sampling bias, and ability to effectively collect representative data.

  • Regression

    Regression analysis is a statistical technique used to model and analyze the relationships between variables. This skill is measured in the test to assess a candidate's proficiency in fitting regression models, interpreting coefficients, and making predictions based on the model.

  • Sampling Distributions

    Sampling Distributions involve the theoretical distributions of statistics calculated from different samples of the same population. This skill is measured in the test to evaluate a candidate's understanding of sampling distributions, including the central limit theorem and the concept of standard error.

  • Exploratory Data Analysis

    Exploratory Data Analysis (EDA) involves the process of summarizing, visualizing, and interpreting data to gain insights and identify patterns or trends. This skill is measured in the test to assess a candidate's ability to perform data exploration techniques, such as plotting graphs, calculating summary statistics, and detecting outliers or missing values.

  • Non-parametric statistics

    Non-parametric statistics are statistical methods that do not make any assumptions about the underlying population distribution. This skill is measured in the test to evaluate a candidate's knowledge and application of non-parametric tests, such as Mann-Whitney U test or Wilcoxon signed-rank test, when dealing with data that does not meet normality assumptions.

  • Probability

    Probability refers to the measure of the likelihood of an event occurring, based on the ratio of favorable outcomes to the total possible outcomes. This skill is measured in the test to assess a candidate's understanding of probability theory, including conditional probability, independent events, and probability distributions.

  • Data Analysis

    Data Analysis encompasses the process of inspecting, cleaning, transforming, and modeling data to discover useful insights and support decision-making. This skill is measured in the test to evaluate a candidate's proficiency in applying statistical techniques and interpreting results for practical data-driven problem-solving.

Do you have any anti-cheating or proctoring features in place?

We have the following anti-cheating features in place:

  • Non-googleable questions
  • IP proctoring
  • Screen proctoring
  • Web proctoring
  • Webcam proctoring
  • Plagiarism detection
  • Secure browser
  • Copy paste protection

Read more about the proctoring features.

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.
