u03a2 Project – Charts, Graphs, and Data Sets
Scott Macdonald

The third step in the process of your statistical project is to determine how the data should be displayed. Depending on the emphasis you are trying to make, bar graphs, pie charts, tables, or another type of display may be used.

Complete the third step in the Statistical Survey Direction Document. Consult the Charts, Graphs, and Data Sets Scoring Guide and the Statistical Survey Project Description and Scoring Guide prior to submitting your assignment. Submit your completed assignment in the assignment tool by the end of Unit 3.

If you would like feedback from your peers prior to submission, post your completed paper in the Optional – Project – Charts, Graphs, and Data Sets Draft discussion.


Activity

This portion of the project has two parts, both involving the graphical representation of data. Histograms are good for representing quantitative data, while pie charts can often be used to represent qualitative data.

Part One: Select Histograms

Complete the following:

  1. Consider the data listed for Question 1 (that is, How old are you?), as found in the file Survey Data. Organize this data, and draw a histogram on a sheet of paper.
    Constructed Historgram Ages histogram for u03a2
    Selected File "Ages3"

    Chosen Ages histrogram #3

    Ages 3 Histogram was selected from the available 4 choices


  2. Do the same thing for Question 5 (that is, How much money do you usually spend per month on soft drinks?).
    Constructed Historgram Spending histogram
    Selected File "Spend2"

    Spend 2 choice histogram

    Spend2 Histrogram was selected from the available 4 choices


Part Two: Select Pie Charts

Complete the following:

  1. Consider the data listed for Question 2, Question 3, and Question 4, as listed in the Description section.
  2. Calculate the percentage of survey responses to each answer for each question.
  3. Gender: Male = 34%, Female = 66%
    Favorite Soft Drink: Tango Soda = 32%, Toca-Cola = 24%, Limon Bubble = 19%, Major Pepper = 11%, Other = 9%, Root Beer = 5%.
    Changed Favorite Soft Drink?: Yes = 29%, No = 71%

  4. Draw pie charts on a sheet of paper to represent the responses for each question.
  5. Gender of People Surveyed:
    Male = 34%, Female = 66%

    Constructed Pie Chart Selected File "Gender3"
    Gender of surveyed Gender #3

    Favorite Soft Drink:
    Tango Soda = 32%, Toca-Cola = 24%, Limon Bubble = 19%, Major Pepper = 11%, Other = 9%, Root Beer = 5%.

    Constructed Pie Chart Selected File "Fav4"
    Favorite Soft Drink Favorite #3

    Changed Favorite Soft Drink?:
    29% "Yes", 71% "No"

    Constructed Pie Chart Selected File "Change2"
    Favorite changed? Change #2
