Explore the principles of statistics and probability, equipping high school students with essential skills for data analysis and informed decision-making.
In real life, we can't always study everyone, so we take samples—smaller groups that represent the whole population.
We use data from samples to make predictions about the whole population. This process is called statistical inference.
Because samples are only part of the population, our results may be a little off. The margin of error tells us how much.
