    4. Insert a scatterplot with the scores on the y-axis and the students ages on the x-axis
    5. Select the data and calculate the correllation coefficient (it will be a number between -1 and 1)
      You will find this function from the top menu bar, select Tools, then select Data Analysis
      (IF You do not see Data Analysis under the Tool menu, you can add in by selecting Add-Ins from the Tool menu, and selecting the top two Add-ins. )
      Then select Correlation (select the data to be analyzed, and select where you would like the correlation to be displayed - by default it will insert a new worksheet with the correcation table, but you can specify a location on the sheet with your data (like cell A25)
    6. Compare your data with the data from other students, see if you can adjust your data to get negative correlation, and then adjust your data again to get a positive correlation.
    7. What does your scatterplot look like with the correleation coefficient is close to 0?

Agenda for Thursday September 29, 2011
Computer Lab Activity #1
Checking the Data Analysis Took Pack
Enable the Excel Data Analysis Tool Pack
  • Excel 2003 and earlier
    1. From the Tools menu bar select Add-Ins
    2. In the Add-Ins dialog box, make sure that the Analysis ToolPak check box under Add-Ins available is selected.
    3. Click OK.
  • From Excel/Office 2007 and later
    1. Click the Microsoft Office Button
    2. click Excel Options.
    3. Click the Add-Ins category.
    4. In the Manage list, select Excel Add-ins, and then click Go.
    5. In the Add-Ins dialog box, make sure that the Analysis ToolPak check box under Add-Ins available is selected.
    6. Click OK.
Accessing the Histogram Functions Adding a histogram is different than inserting other types of charts. The histogram function, along with other data analysis tools will be accessed from either the Data or Data Analysis tools.
  • Excel 2003 and earlier
    1. Select [Tools] from the top menu bar
    2. Select [Data Analysis]
  • From Excel 2007 and later
    1. From the top ribbon, select [Data]
    2. In the Analysis group, select [Data Analysis]

From there, select Histogram, and set the parameters according to the data you want to be displayed in your histogram. Keep in mind, that it is not necessary to have each data element represented in its own "bucket", but that your histogram will contain a series of "buckets" that represent a range of your data. For example, if we had a list of ages for all of the people who live in Wenham, we might show a histogram of buckets for ages 0-5, 6-12, 13-19, 20-30, 30-50, 50 and over.

Computer Lab Activity #2
Creating a Histogram
Save (and then open) the file Ch04_Sugar_in_cereals.xls
  • Notice that there are two columns with data - the name of the cereals, and the percentage of sugar.
  • We want to add a histogram, that will count the number of cereals that have 0-9% sugar, 10-19% sugar, 20-29% sugar, and more than 30% sugar. To do this, we can add the definitions of these "bins" to the spreadsheet. Add the following data to your spreadsheet. Column D is used just for spacing.
    D
    Bin
    9
    19
    29

    We'll now use the data analysis tool pack to add a histogram. We'll tell it where the data is, where the definitions of the bins are, and where we want the output to go. We'll tell Excel that we want the histogram to go on the same spreadsheet, staring at position F4.

    1. In the Data Analysis dialog box, click Histogram, and then click OK.
    2. In the input range, enter (or select) B2 to B50 ($B$2:$B$50)
    3. In the bin range, enter (or select) D1 to D4 ($D$1:$D$4)
    4. Check the box that says Label - notice that we selected the name Bin in our bin range
    5. In the output options, select Output Range F4
    6. Click [OK]

    Things to notice and experiment with

    • we didn't need to add a bin for more than 29, Excel added the "more" row for us.
    • You can add more bins as needed, or make the bins more meaningful.
    • Select Histogram again, change the Output range to "F14" and check the box Chart Output
    • Try some of the other histogram options
    • Sometimes it may help to sort the data to determin the best bins to use.
