THE BASICS; how are scores on the ultrasound board exams
!| !| !| !| !| !| !| !| !| !|
related to study time? - ✔✔directly ;!| !| !| !| !| !|
two variables are related when changes in one variable result in
!| !| !| !| !| !| !| !| !| !| !|
changes in the other. when the changes go in the same direction
!| !| !| !| !| !| !| !| !| !| !|
(both increase or both decrease), variables are directly related.
!| !| !| !| !| !| !| !| !| !|
Since scores increase as study time increases, these variables

!| !| !| !| !| !| !| !| !| !| !| !| !| !|
pounds.

!| !| !| !| !| !| !| !| !| !| !| !|
units of distance !| !|
squared. For example, a rectangle's area is !| !| !| !| !| !|
its length multiplied by its width, and can be reported in square
