Name _____________________________________Due May 3, 2016 Data Analysis Project (Late projects lose 10 points per day) Task: You will conduct an investigation to describe characteristics of the typical 9th grade student at Penncrest HS. You will collect data for both a quantitative and a qualitative variable, analyze the data, and display the data in the following ways. 1. Come up with a quantitative survey question and submit for teacher approval. You must have at least 4 different numerical responses. Quantitative examples include: How tall are you in inches? How many members are in your family? How many siblings do you have? How many hours a week do you work? How many letters long is your first name? How many friends do you have on Facebook? How many times do you text during the day? 2. Come up with a qualitative survey question and submit for teacher approval. You must have at least 4 categorical responses. Qualitative examples include: What is your favorite sport? What is your favorite subject in school? What is your eye color? What is your favorite type of music? What is your favorite snack? 3. Collect data for 40 students. You must turn this in with your final project. You may use the same 40 people for both questions. 4. Analyze your quantitative data. You may use the organization handout given to you in class or you may come up with your own way of presenting the data. -Determine the mean, median, and mode -Calculate the range and standard deviation -Make a box and whisker plot -Determine the interquartile range and determine if there are any outliers -Make a frequency table and probability distribution chart (*See me if you want to make a grouped frequency chart) -Make a histogram -Make a stem and leaf plot (See me if you have too many stems). 5. Analyze your qualitative data. You may use the organization handout given to you in class or you may come up with your own way of presenting the data. -Create a frequency table -Determine the mode -Create a bar graph -Create a circle graph 6. Write a short paragraph (4-6 sentences) describing what you’ve learned about the outcome of your survey questions. Using your data, how would you describe the typical 9th grade student? Use mathematical terms.
