STAT 02.260 - Statistics I

CATALOG DESCRIPTION:

STAT 02.260 - Statistics I - 3 s.h.

Prerequisites: Equivalent of College Algebra

Students learn to use various graphical displays and measures of location and variability to describe data. The course considers elementary probability and sampling distributions, and uses the normal and t-distributions in estimation and hypotheses testing. It includes descriptive techniques for simple linear regression and correlation. Use of a graphing calculator is required; computer software may be used. Students are expected to have completed an equivalent of College Algebra.


OBJECTIVES:

The objectives of this course are to familiarize students with basic statistical terminology and tools for describing data sets. Students will also obtain a knowledge of basic concepts in data description, hypothesis testing, statistical inference and obtain a firm basis for further statistical study. Students will be exposed to the importance of the basic assumptions underlying all statistical calculations
