30.003 Introduction to Probability and Statistics

No. of Credits: 12 Subject Credits



The aim of this course is to introduce concepts of Probability and Statistics.

Learning Objectives

  • Apply key concepts of probability, including discrete and continuous random variables, probability distributions, conditioning, independence, expectations, and moments
  • Define and explain the different statistical distributions (e.g., normal, log-normal, Poisson) and the typical phenomena that each distribution often describes
  • Apply the basic rules and theorems in probability including Bayes’s theorem and the Central Limit Theorem (CLT)
  • Define and demonstrate the concepts of estimation and properties of estimators
  • Apply the concepts of interval estimation and confidence intervals
  • Apply the concepts of hypothesis testing and p-value
  • Apply the method of least squares to estimate the parameters in a regression model
  • Use software to facilitate statistical analysis

Measurable Outcomes

  • Evaluate the probabilities and conditional probabilities
  • Evaluate expectations and conditional expectations of random variables
  • Approximate the distribution of sum of random variables using CLT
  • Construct point estimators using the method of maximum likelihood
  • Calculate the number of samples needed to construct confidence levels on the mean and variance of a normal distribution
  • Design hypothesis tests for a given set of data and select the appropriate thresholds for the tests
  • Use linear regression analysis to develop an empirical model of experimental data.
  • Apply computer programs to facilitate the analysis of data.
