14 – Assessment and Evaluation
Calculated questions allow the use
of variables, and if you scan this
code you will notice the variables
by looking for braces, e.g., { }. Using
the variable feature of calculated
questions enables you to
generate hundreds of examples
from one question.
Given the following population distribution, what is the probability calculation of (to 3 decimal places):
P (B and S)
 
The population under study is
a jar of marbles with the following composition:
COLOUR
LARGE
SMALL
RED
{r2}
{r3}
GREEN
{g2}
{g3}
BLUE
{b2}
{b3}
ORANGE
{o2}
{o3}
I created this code in the HTML
editor Dreamweaver, which gives a
WYSIWYG view of the variables.
