STT215 Learning Outcome Describe the variability inherent in univariate and bivariate data in numerical, graphical and written form. Explain the role randomization plays in designed experiments and in standard sampling methods. Compute and interpret probabilities of events in everyday random phenomena and of common sampling distributions. Compute and interpret confidence intervals in one-sample and two- sample cases. Construct hypotheses testing in one-sample and two-sample cases, and interpret the results utilizing p-values to draw statistical/non- statistical conclusions.

STT215 Learning Outcome We covered the most fundamental backgrounds for Probability and Statistics. You have solid foundation on Statistics and Probability. You are well prepared for any advanced graduate level statistics/probability courses. You are ready to work alone on statistical data analysis and scientific hypothesis testing. STT215

Summary to STT215 class It is a fundamental and useful class. Steep learning curve. Reasoning makes it challenging. Twisted with algebra. It has its realm of notations and ideas, which are totally different from most Mathematical courses. Critical thinking is challenging! Logical thinking is even challenging! STT215
