1) Below are the scores (out of \(10\) points) for the first quiz in your math class.
1a) Drag the "Items" slider and populate the dot-plot. What trends do you see?
1b) Slide "Items" back to zero. Check the Median and Mean boxes. Slide the "Items" so "Items=2", why do the Median and Mean outputs make sense?
1c) Slide "Items" half way so "Items=12" record the Median and the Mean. Then slide "Items" to "Items=24" why do they both increase?
