STAT2800: Midterm Review
MIDTERM REVIEW
1. Chapter 1 is pretty straight forward. Please make sure you
understand your simple summary statistics of a raw data set
x
(i.e., x, s 2 , ~ , quartiles, etc). Also, please understand the three
graphical summaries:
CARTESIAN VECTORS AND
THEIR ADDITION & SUBTRACTION
Todays Objectives:
Students will be able to:
a) Represent a 3-D vector in a
Cartesian coordinate system.
b) Find the magnitude and
coordinate angles of a 3-D vector
c) Add vectors (forces) in 3-D
space
