Statistical Estimation
Statistical estimation is a method used to make educated guesses about a larger group based on a smaller sample. For example, if you want to know the average height of students in a school, you might measure just a few students instead of everyone. Using calculations, you then estimate the average height for all students. This process helps us draw conclusions and make informed decisions when collecting data from an entire population is impractical. Estimation relies on mathematical formulas and principles to ensure that the guesses are as accurate and reliable as possible.

Statistical estimation is a method used to infer information about a larger group (population) based on a smaller sample. By analyzing the sample data, statisticians can make educated guesses (estimates) about unknown parameters, such as average income or the percentage of people supporting a policy. This approach relies on the idea that the sample reflects the population's characteristics. Two common types of estimates are point estimates, which provide a single value (like an average), and interval estimates, which provide a range (like confidence intervals) to express uncertainty around the estimate.
