Statistical Inference
Statistical Inference is a way of drawing conclusions about large groups by studying smaller samples. Think of it like tasting a spoonful of soup to judge the whole pot. When you see this on a resume, it means the person knows how to make reliable predictions and decisions using data. They can take information from a smaller group and figure out what it means for the bigger picture. This is important in market research, scientific studies, and business decision-making. Related terms include "data analysis," "statistical modeling," and "quantitative research."
