# EN330: Probability and Statistics with Ocean Applications

## Catalog Description

### EN330: Probability and Statistics with Ocean Applications (3-0-3)

The course is designed to give a basic understanding of probability and statistics, as related to engineering problem solving, with an emphasis on marine applications. Topics covered include basic descriptive statistics, probability analysis, probability distributions, uncertainty estimation, time-series analysis, confidence limits, and regression analysis. While the course involves a blend of theory and analytics, practical applications of probability and statistics to engineering in the marine environment will be emphasized. Additionally, this course covers the general topics of the Fundamentals of Engineering (FE) exam.

### Textbook

*Basic Statistics*(Lind, Marchal, and Wathen)

### Goals

- Understand and relate fundamental concepts of statistics and probability to real-world engineering applications, particularly those pertaining to the marine environment.
- Develop and implement computer algorithms to analyze and display random data (in the form of histograms, cumulative distributions, sea-surface elevations, etc.) for purposes of engineering decision-making.
- Assess uncertainties in data sampling through statistical inference techniques to develop point estimates and confidence intervals for estimation of the (population’s) mean and variance.
- Apply knowledge of probability and statistics to develop a statistical description of the random sea surface, including application of the Gaussian distribution to water surface elevation and the Rayleigh distribution to wave heights.
- Relate to all topics covered on the Fundamentals of Engineering (FE) exam – Probability and Statistics portion – including a familiarity with the FE reference manual and an ability to answer FE-approved sample problems in a time-efficient manner.
