Assignment: Box-and-Whisker Plot Practice (link!)
Use your notes as needed to complete these five-number summaries and create your box plots.
*Focus on the medians: first find your actual median, then the median of the upper and lower sets of data.
*If you can't remember what to do with data that does not divide easily into four equal sets (quartiles), please use this link that is also available on the Mo'Help tab of this blog.
*If you have questions about how to draw the box plots you can use this link. (also available on my blog).
Be accurate and tidy in your work.

Assignment: Central Tendency ws 14 - link!
There are easier parts to this assignment and ones that will require more careful and critical thinking.
*For questions 1 - 4, use the table and be careful to answer all parts of the questions. Be sure to show and attach all of your math work!
*For question 5, after you have your answer work through the problem and see if your "solution" fits the wording. This is not a trick question, but you do need to make sure you understand Gina's situation.
*For question 6, note that you will have to determine that IF the median is "10" after 6 calls, you will need to make an ordered list to determine what that call length was. They do not GIVE you the call length, you have to figure it out based on the information you have been given.
*For question 7, you only get one chance to answer this question (multiple choice), so again be sure that your answer works with the opening statement as well as the quotes from each of the girls.
Checking your answers back with the original question for all of the problems will help you to catch any misunderstandings before you turn it in for credit!

Assignment: Sodas WS - link!
Using the histogram provided, answer the questions on the page.
*When it asks you to explain, explain. Seriously. How did you use the data?
*If you need/want to draw more horizontal lines to read the graph better, I certainly recommend it. You will be responsible for being accurate ... don't guess.
*The numbers will all be whole numbers: no half students or partially consumed (thanks, Sophie!) sodas.
*Gabriel noticed that the labels on the left side of the grade could be misleading ... they represent the number of students who answered that question in that category (number of sodas) much like we do on our graphs in class. Thanks Gabriel!
Like I told you in class, this worksheet looks simpler than it is. On the other hand, if you work backwards and create your organized list, these questions WILL be easy to answer. Just take your time and be thorough.

Assignment: Slugville! (link)
In this assignment you need to read the story and then answer questions a through f.
*You MUST calculate the mean, median, and mode for these problems. You will calculate them again for question "f."
*Show your work for the calculations either on the page or another sheet of paper. You may NOT use a calculator.
*Explain your reasoning thoroughly as I cannot read your mind. Just giving the answer is not enough if you do not back it up with an explanation of how you came up with your answer.
*For question "e," be convincing. I am asking for YOUR opinion. There is no one "right" answer, but you do need to convince me that you are right!
Extra Challenge: Can you identify the three current 8th grade NOVA students running for mayor in Slugville!??!?!

Assignment: Flea Market Frequencies (link!)
On this worksheet you will see a list of 40 sale prices for items that sold at the imaginary flea market. They are in random chaos order, but fortunately you are not required to organize them for this assignment! You will, however, be responsible for tallying each of the sold items in the appropriate boxes of the given frequency table.
*Note, the tallies for the items selling between $16 - $20 has been completed by the worksheet designer, so mark those items off the list before you begin!
One you have them all tallied, complete the Histogram (once again, the $16 - $20 category is completed already) by shading in the appropriate boxes, then answer questions 3 and 4.
You may use color if you would like it to look interesting, but it is not required. ACCURACY of your tallies and histogram making is what matters.

Assignment: Mean, Median, Mode, pg 51 (link!)
This IS a longer assignment, so take your time to be accurate as it will save you more time in the future. You must turn in your work with this assignment whether it is on the front or back of the worksheet OR on another sheet of paper that you staple to the worksheet.
*First, create your ordered list.
*Count carefully the number of numbers in each set of data; you want to divide by the correct number.
*Add carefully when determining your mean, otherwise you will end up with crazy numbers as answers. Please note that crazy numbers as answers mean you did something incorrectly, so rather than divide incessantly, add the numbers up again.
*Note that the "mean" may be a decimal; you may also write it as a fraction or with a remainder if you need to. As a hint, this only applies to the "Test Scores" and "Homerun" mean categories. The only mode with a decimal answer is "Hourly Wages."
Accuracy is extremely important in math, so work carefully with no distractions. Again, you may not use calculators and all of your work must be turned in with the assignment.

Assignment: Perfect 10 (link to worksheet)
In this assignment, you have been given "10" as the answer to the question. Your job is to figure out which of the central tendencies "10" represents in each of the given number sets. Then using the central tendency that you determine is the answer, fill in the blanks for the "Fun Fact" with the corresponding letter to the problem number at the bottom of the page. The answer will be two actors that you most likely do not know, so ask your parents if your answer looks reasonable!
*Definitions for each of the central tendencies are given at the top of the worksheet; you should also have the definitions we recreated in class today in your notes.
No calculators are allowed for this assignment and you need to show your work (any needed math computations) on either the front or back of the worksheet, OR on another sheet of paper that you attach to this worksheet. Be efficient! ;-)

Homework for Tuesday, September 13
Coin Data: Frequency Table and 3 Histograms
Never underestimate the power of being able to read and interpret graphs deeply. We will be practicing that, you know: deep interpretation.
Frequency Table -
*Your sheet should list all of the years from 2016 to your oldest coin.
*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)
.JPG)
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!

Assignment: Coin Data
Today in class you received a random sample of 20 pennies from my home stash.
1) Your first task was to predict, in one minute, what the years for your sample of pennies would be and why you thought that. You might have spoken in terms of range, or clusters, or even specifics, but the point was to let me know how you think.
2) Your next task was to organize your second paper by dividing the page in half down the middle.
-On the left side your heading should be Random Chaos.
-On the right side your heading should be Organized List
*Your next task was to go through your pennies one-by-one in random form, writing down the year of each penny as they occur in the left column. You should have twenty different data points, meaning you should write each year every time it occurs.
*On the right side of the page, you create your organized list from your random chaos data. Begin with the newest penny at the top and work down to the oldest. Again, you should have twenty different data points, meaning you should write each year every time it occurs.
3) Finally, on your prediction page, you are to make a three minute observation regarding your data. Make it interesting, use examples, make it detailed, and show me your awesome math mind. Let me know how you are thinking ... I want to see how your mind works and I will only know if you tell me. ;-)
Your Prediction, Lists, and Observation are due on Tuesday, September 13.
