PART B:  Complete Descriptive Statistic analysis of your data

You will now be working with your partner(s) for the remainder of the Final Project.

• You will choose ONE data from Part A to move forward with.  Be sure everyone in the group understands the data!
• Working together does NOT mean "divide and conquer."  EVERY member of the group is responsible for EVERY part of the project.  Your work together should be similar to the work you do on the Unit Projects: everyone does the work and double-checks each other's work.
• You will be submitting ONE "Part B" for the group, and everyone in the group will receive the same grade UNLESS it comes to the professor's attention that not everyone contributed equally.  Group members are responsible for communicating with the professor if there are issues.

In this portion of your project you will be using the strategies of Descriptive Statistics to begin the analysis of the data you gathered in Part A.  A couple of key points to keep in mind:

• You are expected to use correct statistical notation and terminology, and you should be using statistical concepts as they were covered in our class.
• Any large numbers that your calculator gives to you in scientific notation must be written out in standard form (for example, 3.2E5 needs to be written as 320,000). If numbers are more than 4 digits, you must use commas when writing the numbers (for example, 320,000 not 320000).
• When describing/explaining your data and results, be sure to include appropriate units (for example, dollars or degrees Fahrenheit per year or deaths per 10,000 people)

For this part of your project, you will complete the work on SEPARATE PAPER and attach it as a SINGLE .pdf file.  You will probably have multiple pages, so be sure to put all the pages together into a SINGLE submission.  This free online tool from Adobe will help you put multiple pdfs together into a single document:  https://www.adobe.com/acrobat/online/merge-pdf.htmlLinks to an external site. 

Below is what needs to be submitted for part B.

1. PAGE 1:  DATA  : You have already submitted your sample data with Part A, but please submit again.
   1. If you made any changes to your original data submission, please make note of any changes made.
   2. Be sure your data table has an appropriate title and the that columns are clearly headed with the relevant information for each.
   3. The data should be on the first page by itself, and should all fit on a single page.  Do not begin the histograms & other descriptive statistics until page 2. 
2. HISTOGRAMS  Create two frequency histograms, one for each of your samples.  (These can be CAREFULLY hand-drawn images or made with technology.)
   • Note you’ll need to create a frequency distribution table in order to create your histograms.
   • Use 6 classes for your histograms. (If your data does not work with 6 classes, please use a number of classes that makes sense: you need at least 5, but no more than 10).
   • Just as you did for the Unit 1 Project, be sure you are using the same classes for BOTH histograms so you can easily compare them! (This means using the LOWER of the  two minimums and the HIGHER of the two maximums to create your classes.)
   • Be sure to include an appropriate title and scaling as we have discussed in class (WARNING: many technology options don't label histograms as we talked about in class.  You need to use the standards we talked about in class for your horizontal axis scale/labeling.)

1. BOXPLOTS  Create side-by-side box plots for your samples; make sure these use the same scale and are in fact side-by-side. (These can be CAREFULLY hand-drawn images or made with technology.)
   • Each boxplot must have the 5-number summary values listed in the appropriate location on the boxplot.
   • Be sure to include an appropriate title and scaling.
   • Be sure to check for outliers and show them appropriately on the boxplots.

1. NUMERICAL ANALYSIS:   State the sample mean and sample standard deviation for each of your samples.  (We will be using these measures of center and spread for our data...the reason will become clearer as we move into Inferential Statistics).
   • Use correct statistical notation.
   • Be sure to include appropriate units.
   • Be clear which statistics go with which samples.

1. INITIAL SUMMARY  Do an initial summary of what you are seeing with your descriptive statistics.
   • Talk about any similarities and differences you detect between the groups.
   • Talk about what the mean and standard deviation tell you about the data sets.
   • Be sure you discuss the shape, center, and spread of the data.
   • What initial conclusions, if any, can you can draw from the descriptive statistics from parts 2, 3, and 4?
