Applets (website or
disk)
Under Student Categories or Student tools, choose "Statistical
Applets."
I know we'll use these:
One-variable Statistical Calculator,
Mean & Median,
Normal Density,
Correlation/Regression,
Simple Random Sample: For example, To pick
a sample from a "Population" list labeled 1 to 138, enter 138 in the
top
box, hit Reset. Put the size of the desired sample in the bottom
box.
Hit Sample. The sample numbers move to the right-hand
column.
To pick a different sample, hit Reset, then Sample.
This can be used to allocate units for an experiment like
this;
Suppose 12 units and 3 treatments. Each treatment should get 12/3
= 4 units. Put 12 in the population box, 4 in the sample box. Hit
Sample to choose the 4 numbers for the units to get treatment 1.
Hit Sample again (don't Reset) and it will choose the 4 from the
remaining
pool to get treatment 2. The remaining 4 will get treatment
3.
You can select and copy (Ctrl-c) the sample numbers into a Word
document.
Probability For a fair coin,
leave
probability at .5. It accumulates tosses until you hit Reset.
