Understanding Basic Statistics
Statistics is the science of collecting, organizing, and making sense of information. It's like being a detective with numbers! When looking at a group of numbers, there are several ways to describe what's typical.
The mean (also called average) is found by adding up all values and dividing by how many values you have. The median is the middle value when all numbers are arranged in order. The mode is the value that shows up most often in your data.
The range tells you how spread out your data is by finding the difference between the highest and lowest values. For more advanced statistics (which you'll learn later), standard deviation measures how much values typically differ from the mean, while margin of error tells how accurate a statistical measurement might be.
Quick Tip: When data contains outliers (values much higher or lower than most), the median often gives a better picture of what's typical than the mean.
