Applets designed for use with D.S.Moore textbooks, but good anywhere:
  http://bcs.whfreeman.com/scc or http://bcs.whfreeman.com/ips4e,.   http://bcs.whfreeman.com/ips5e. Under Student Categories or Student tools,  choose "Statistical Applets."
Mean & Median, Day4 (probably)
Normal Density, Days7, 8, 9 (probably)
Correlation/Regression, Days 11, 13,  14, 16, 17, 18 (probably)
Simple Random Sample:  Day 22.(probably)  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 Day 23, HW Day 26.  For a fair coin, leave probability at .5.  It accumulates tosses until you hit Reset.

ActivStats tools:
AS5-3, click on top righmost button (red dots on yellow background, "Tool1")  After the Dotplot Tool opens, right-click to get menu. In it,  Click on (choose)  Show Buttons, Centers, Spreads, Mean Graphically, Standard Deviation Graphically.   Then you can click in the yellow area to add points.  You can drag points. Check that the dark band shown goes from 1 s.d. below the mean to 1 s.d. above the mean. Experiment, especially  with the results of outliers on the S.D. & IQR (You can show only one middle, one spread graphically at a time but you can right click and change which one at any time.) Day6 (probably)

AS6 Normal Density tool: Use AS30-2 "Normal distribution based Confidence Intervals" tool for best setup.CAUTION: Don't hit the Enter key! It closes the tool-box!   To use it from Tool1 from the menu bar in Ch. 6:  Right click for menu. Choose Show Buttons.  Choose Show Flag Values, Mean, StandardDeviation; Real Values.  Now you can type in mean and s.d. and  the mean + 1,2,3 s.d.'s will show on the axis.  CAUTION: Don't hit the Enter key! It closes the tool-box!  To register a typed number, click in a different box.   Days7,8, 9(probably)

ActivStats 7-3, correlation:  2nd activity:  Slider to see shapes ~~ r's.  3rd activity: non-linear data and r's. 4th: center and scale change.
Activstats has some  scatterplot tools, (ch. 8)  like the Correlation/Regression one on the Moore websites above.  It Doesn't allow the Xbar, Ybar lines, so for correlation I prefer the Moore tool.

ActivStats Least Squares tool:AS8-3, rightmost button, with line and red dots. "Show" button.  Checkmark all possibilities. Uncheck "ShowLS Line". Choose number of points, Do "Regenerate". Move green line to minimize Sum of Squares (red bar), and observe residuals as you do.  Confirm your result by checking "ShowLSLine".
"Regenerate" created "good clouds" of data.  To use your own data, do "Reset"; click in the picture to make dots (but not too close to the green line or it will think you're dragging that.).  Day 17, 18?(probably)

HANDOUTS (not all handouts are web-able.  Look in the white folder outside my door for paper.)
Optional SPSS handout to create new computed variables.   Days7 (probably)
, Using SPSS to find a Simple Random Sample. Day19 (probably)
