The Challenger space shuttle disaster was blamed on faulty O-rings. How can probability calculations on random variables help predict the chances of this kind of failure?
Casinos are as well versed in probability as statisticians and probability models help them maintain the house advantage over gamblers.
Probability is the mathematics of chance behaviour - and can help predict events such as the daily weather, or whether an asteroid will collide with Earth.
A visit to the University of New Hampshire Survey Centre illustrates how pollsters create accurate surveys. They can then use details from their sample to make inferences about a whole population.
Does holding a heavier clipboard make you estimate that a jar of coins has more money in it than if you're holding a lighter clipboard? Psychologists use one-way ANOVA to analyse the data from this experiment.
Historical story of how statisticians built the case against DDT as the culprit behind plummeting peregrine falcon population numbers.
Host Dr Pardis Sabeti's own research examines possible genetic resistance to deadly Lassa fever in West Africa. Using inference for two-way tables helps untangle potential relationships.
Managers have no clue what conditions actually motivate their workers best, as shown by research conducted by Teresa Amabile, host of the original Against All Odds.
Comparing the activity and calorie expenditure levels of Western office workers and African hunter-gatherers adds some surprising new data to the science of obesity.
A brewer uses this technique to monitor quality differences in multiple batches of the same beer.
Is a newly discovered poem really written by William Shakespeare? Using statistical analysis of his known word use, researchers set up null and alternative hypotheses to investigate.
A battery manufacturer tests just a sample of its product to verify its claims about battery life. A margin of error and a confidence level help quantify its accuracy.
This quality control method helped Quest Diagnostics streamline and improve their system for processing and testing lab samples so they could meet their nightly deadlines.
Heights of third graders in one class. Quality scores for circuit boards at a factory. Taking multiple samples allows us to visualise the sampling distribution of the sample mean.
Sickle cell disease is an example of binomial distribution in families with two parents who are carriers for this genetic trait.
The US counts every resident every 10 years, or at least tries to. Statisticians use sampling from a population as an alternative to a complete count, as utilised at a potato chip factory.
We move beyond observational studies, like the one of marine life in the remote Line Islands, to designing experiments that manipulate various subject groups, as in the case of a medical study about osteoarthritis treatments.
This historical story describes how researchers untangled the relationship between smoking and lung cancer.
