Portfolio assignments are extended assignments that typically take about an hour to complete. If you are spending a lot more time than that, you are taking too long. Don't hesitate to reach out for help. I often do one-on-one LiveLessons regarding portfolio assignments. Find on this page helpful instructions and resources to explain any changes to the assignments and provide assistance.
Unit 1 - Graphs
In this assignment you are given a table of 64 survey responses with "Agree", "Disagree", and "No Opinion" as possible responses. Your task is to create two graphs, a bar graph and a pie chart. Bar graphs are useful for comparison, while pie charts show the part of the whole. Both are useful, but reveal different things. In the following video, I have chosen to create the graphs in Microsoft Excel. If you are using a Connections Academy computer, you should have Excel installed on your computer. If you do not have Microsoft Excel, the same thing may be done in Google Sheets or any other spreadsheet program, such as Open Office. Only the menu choices and steps would be different in each of these. Do note, you may choose to make these graphs by hand, on graph paper. That is perfectly fine. For the pie chart, it will be important to use a ratio to calculate the central angle of each pie slice, and carefully measure those angles with a protractor.
Unit 2 - Interpretation of Data
In this assignment, you are to calculate the mean, median, mode, range, variance, and standard deviation of a list of 24 numbers. Complete work includes a table showing the calculations. All steps for variance and standard deviation need to be shown in the table. This may be done on paper, in Word, or, as in the video below, in a spreadsheet, such as Excel.
Unit 3 - Collection of Data
In this assignment, you are to design a questionnaire for a survey. The questionnaire must have at least 5 questions, and be given to 10 people. I would also like for you to use at least three types of questions: open response, numerical response, multiple choice, etc.. Additionally, summarize your results. Be specific on each of the 5 questions.
Unit 4a - Uses of Data Portfolio
In this assignment, we create a scatter plot from bivariate data, draw the line of best fit, write the equation of that line, and use the equation to make prediction. Do not use the data in the video. It is only an example. Use the data you were given in the lesson. You may submit your work on paper, or in Word or, as I have done, in Autodesk Sketchbook.
Unit 4b - Uses of Data Activity
This portfolio outlines 7 steps for doing a statistical study. Use the lesson materials to walk through each of the 7 steps. Remember, this is a writing assignment. So thorough answers for each of the 7 steps are expected. In this video, I walk through an example for Tyrel's T's. This is an example. Make sure to make your own example with it's own data.
Unit 6 - Probability Models
In this portfolio, you are given a list of 20 data points (numbers) and are asked to determine if they are normally distributed. In the video below, I take a similar list, calculate the standard deviation, and use that to determine if my list is normally distributed. Make sure not to use the list I use in the video, but use the list given you in the portfolio assignment.
