Mat 6/7
1) Finished quiz over the graphs we have learned.
2) Worked on p. 300-301 #2, 5, 6, 10, 12, 14. It deals with mean, median, mode, range and outliers. You may use a calculator on your homework. Please bring that calculator to class. We will be using them for the next few days.
HW: Finish p. 300-301 #2, 5, 6, 10, 12, 14.
All portfolios and presentations are due on Monday, August 31!!!! If you would like to print off your graphs, I will be in the Mac Lab tomorrow morning from 8:15-8:50. You must have a pass in order to come to the lab. So if you decided to come then print this blog and show it to the study hall monitor.
I have pasted the directions below if you need them.
Histogram:
A Histogram is a useful graphing tool when you want to analyze groups of data, based on the frequency at given intervals. The graphing technique allows you to group the data into ‘bins’ so that it can be easily plotted
Often, a computer will not have a histogram option in Excel’s Chart Wizard. A simple 1- time set up is possible so that Histogram analysis of data will be possible.
1. Open an Excel spreadsheet
2. Go to TOOLS in the menu bar
3. Select ADD INS
4. From the drop down bar pick ANALYSIS TOOL PAK (check this box) and click OK
On your excel spreadsheet, that contains your data, you will need to make a column for the number of bins that you will need. The ‘bin’ is the grouping of data based on the range of data you have. The range of data is often best seen when you use the sorting option from the tool bar:
1. Go to Data in the menu bar
2. Select Sort
3. Choose the column you want to sort and then choose ascending/descending
order. This allows you to see the range of values and helps you determine the number of bins that you will need. (The number of bins should cover the range of your data values)
4. Pick a new column on your spreadsheet and add the bins
5. Go to TOOLS, DATA ANALYSIS and choose Histogram
6. For INPUT RANGE, click on the small box to the right. Highlight the column on your
spreadsheet that contains the data to be binned. This will become the frequency value
7. For the BIN RANGE highlight the bins column
8. Under OUTPUT OPTIONS, select NEW WORKSHEET PLY: and name the worksheet.
This will be set up with a new, titled spreadsheet with 2 columns: bin and frequency
9. Highlight the frequency column of data and go to CHART WIZARD, pick column graph
10. To be sure your x- axis is labeled as BIN, click on SERIES
tab, CATEGORY (X) LABELS. Click on the small box and highlight
your bins column)
11. Complete the column graph as usual
Pictograph
How to Make a Pictograph in Excel
i. This means each picture is one thing (example:1 glass of lemonade)
ii. If the number is 2, then each picture means two things (example: 2 glasses of lemonade) and so on
iii. Check with your teacher before using any number except 1
NOTE: To see the graph better (and to print the graph) click on the graph to show the handles, and go to FILE, PRINT PREVIEW.

We finished up in the Mac Lab today. If you did not get all your graphs printed then you will need to finish them at home. The graphs can be done by hand or if you know how to graph in word or power point then you may do so. I will need a copy of all the graphs and the paragraphs in your portfolio.
HW: Review WS for the quiz
Quiz is tomorrow over frequency tables, line plots, line graphs, bar graphs and histograms.

Today we went to the Mac Lab to retrieve data for our upcoming port
folio project. The guidelines will be posted at the end of this blog in black ink. I hope you found all the data you need because tomorrow we will begin graphing:)))
HW: Double check to make sure your data matches your graphs and that you have data for each graph. If you are planning on printing please bring in 10 pieces of computer paper to due so.
Quiz on Wednesday over graphs we have learned so far. (line plot, bar graph, line graph, histogram, pictograph and frequency tables)

Math 6/7
1) Great Wall of China–How long, in length, is the Great Wall of China?
2) Numerical and categorical data.
Numerical data is when the choices are numbers.
Categorical data is when the choices are categories.
To collect the data, you will need to use a frequency table or line plot to organize the data.
HW: Write a question that requires categorical data and write a question that requires numerical data. Use a frequency table and/or line plot to organize your data. Make sure you have a title on each graph.
