1.2 - The 7 Step Process of Statistical Hypothesis Testing | STAT 502

: Researchers use statistics to determine if a new medical treatment is more effective than a placebo.

Probability provides the mathematical framework for quantifying the likelihood of events. Vjerojatnost i statistika

(Probability and Statistics) is a foundational mathematical discipline focused on understanding uncertainty and making sense of data. While related, they approach problems from opposite directions: probability uses a known model to predict future outcomes, while statistics uses observed data to build or verify a model. 1. Probability (Vjerojatnost)

: Uses sample data to make predictions about a whole group. This includes Hypothesis Testing (using a 7-step process to see if a claim holds up) and Confidence Intervals (estimating a range where a true value likely falls). This includes Hypothesis Testing (using a 7-step process

: Common models used to describe data include the Normal (Gaussian) distribution , Binomial , and Poisson . 2. Statistics (Statistika)

: Techniques used to find relationships between different variables, such as how education levels might correlate with income. 3. Real-World Applications and Poisson . 2.

: Teams use statistics (like "Moneyball" or sabermetrics) for player drafting and strategy.
