Halloween Twitter Problem
(@dmarain)
Treats__Kids
1 ___4
2____5
3____4
4____4
Mπan treats/child? Mπdian?
COREFLECTIONS
(1) This question fits where in Common Core? Grade levels?
(2) What questions could you ask before calculation to develop number sense/conceptual thinking?
Some ideas...
Why is this sometimes referred to as a frequency table?
OR
Which is easier to determine -- mean or median? OR
If frequency = 4 kids for all # of treats, mean = ? Mental Math!!
OR
Explain to your partner why mean > median.
HAPPY HALLOWEEN!!

Basically mean is easy to find but for even numbers median is difficult little bit just select middle two values and add them and divide it by 2 the given answer is median.
