[size=150]Use the slider to increase or reduce the number of values in the set of data values[br]Drag the [color=#6aa84f][b]green triangles △[/b][/color] on the horizontal axis to change the values in the data set.[br]Use the checkboxes to show the mean median or modal values and their positions.[/size]

[size=150][b]Instructions[br][br][/b]1. Move the slider to add 1 more value to the set of values. There should be 6 values now.[br][br]2. Move the [color=#6aa84f][b]green △[/b][/color] [br][br]3. Move the [color=#6aa84f][b]green △[/b][/color] so that this new value becomes very large. This value is now very far right from the rest, and is called an extreme value of the data set. [br][br]4. What is the effect of the outlier(extreme value) on:[br] a. Mean[br] b. Median[br] c. Mode[br][br]5. Repeat step 3 above, but this time, make the value become very small. This value is now a very far left extreme value[br][br]6. Again, what is the effect of the outlier (extreme value) on:[br] a. Mean[br] b. Median[br] c. Mode[br][br]7. Can you explain in your own words why extreme values affect one more than the other ? Which is most affected?[/size]
