MATH 115  Probability and Statistics 



Catalog Desc: 

(Prerequisite: Math 103 or placement by the current assessment methods. Credit awarded for either Math 115 or STAT 115, but not both courses.)
An indepth introduction to probability and statistics appropriate for students in the math and life/earth science disciplines. Descriptive statistics, introduction to probability theory, probability distributions, data sampling, estimation, correlation, hypothesis testing. (CSU/UC) AA/AS Area E, CSU Area B4, IGETC Area 2, CID: MATH 110 



Expected Outcomes: 

1. Organize, display, and summarize a data set using appropriate graphical and numerical methods.
2. Determine the likelihood of events via enumeration methods and known distributions.
3. Make a qualitative or quantitative inference about a population based on a sample. 



Critical Thinking: 

Students must be able to analyze a problem; choose appropriate concepts and methods to be used in its solution; then apply these tools skillfully to solve the problem. "Evaluate", "synthesize", and "differentiate" are all terms applicable to the use of probability and statistics in problem solving.
