OHST Exam Prep: Statistics Made Simple | Mean, Mode, Probability

OHST Exam Prep Series | Field2Compliance Welcome to the Field2Compliance OHST Exam Prep Series, your focused guide to mastering every domain of the Occupational Health and Safety Technologist (OHST) certification. In this full-length video, “Statistics Made Simple | Mean, Mode, Probability,” we break down one of the most challenging OHST math topics—statistics and probability—into clear, job-focused lessons designed for both exam mastery and field application. Drawing inspiration from OHST Exam Secrets by Mometrix and The Safety Professional’s Reference & Study Guide by Yates (not affiliated), this video bridges textbook formulas with real-world decision-making tools used in safety management, exposure tracking, and environmental compliance. What You’ll Learn • Measures of Central Tendency (Mean, Median, Mode) • Measures of Dispersion (Range, Standard Deviation, Variance) • Probability & Sample Spaces (Permutations, Combinations, Multiplication Rules) • Z-Scores & Confidence Intervals • Applying statistics to workplace safety analysis and compliance reviews Each concept is explained step by step using OHST-style examples — inspection times, exposure rates, and PPE performance data — so you can understand not just how to calculate but also how to interpret data in the field. Why This Lesson Matters The OHST exam tests not only knowledge but application. Understanding data trends and probability helps safety professionals: • Analyze incident rates and predict potential outcomes • Quantify exposure limits with confidence • Identify trends in compliance and operational safety metrics • Support data-driven recommendations for hazard reduction By the end, you’ll understand how statistical reasoning supports safety performance and environmental compliance — essential for both passing the OHST exam and applying your skills on the job.
