Preparation Guide Numerical Analysis
This preparation guide helps you to prepare for numerical aptitude assessments. It provides guidance on how best to approach the assessment, allowing you to give your best possible performance.

Why are Aptitude Assessments used?
Employers often use aptitude assessments as part of their assessment procedures for the selection and development of staff. Research has shown that they are powerful predictors of performance at work.

- demonstrate your strengths - be assessed fairly on job relevant criteria - find out more about your strengths and development needs - make future career decisions based on your abilities

Assessments help employers to:
- select people best suited to the demands of the job - identify areas where individuals might benefit from further development - obtain objective information about people’s abilities

Instructions
On the following pages are some practice questions which are similar to those you will be asked in the assessment. Completing these will help you understand the types of questions used and gain experience in taking ability tests. These questions are designed to assess your ability to understand numerical information. You will be presented with a series of tables and graphs, each followed by several questions. Your task is to choose the best answer to each question from the options given. Have a pen and paper to hand to indicate your answers and make notes. You may use a calculator. The actual test is strictly timed. Try to complete each set of 4 questions within 3 minutes.
