Homework for Tuesday, Sept. 15

Coin Data:  Frequency Table and 3 Histograms
Never underestimate the power of being able to read and interpret graphs deeply.  We're practicing that, you know: deep interpretation.
Frequency Table -
*Your sheet should list all of the years from your oldest coin to 2015.
*You should have one color representing your tallies and another color representing your partner's tallies. 
*Tallies should be marked next to the appropriate year; there should be one tally per coin represented.
You will use this table to create your histograms.

3 Histograms -
Here is a visual of the set-up for the three histograms you are to create.  (note they are all on one piece of extra long graph paper turned sideways)

The super important things are that every year is represented, your scale is accurate, you have three colors designated in your legend, and that everything is labeled.
The histograms are stacked on top of one another with each histogram in a unique color as used in your frequency table.  But this time, there will also be a "combined" graph color.  Be sure to make a legend (key) on your histogram sheet with these labeled.
*Each coin should be represented twice:  once in the individual graph and once in the combined data graph. 
*Count your boxes - each individual graph should have 20 colored boxes and your combined graph should have 40.
Graphs are nothing if they are not accurate and not useful if you cannot interpret them.  Be prepared to dig deep tomorrow!
