Chapter 3 Assessment Part 1

Complete the following problems on a separate sheet of paper using your own handwriting (no typing or

digital graphics). Make sure that you show ALL of the steps required to solve each problem. You ARE

allowed to use notes, formula sheets, the book, internet resources, and a calculator. You ARE NOT

allowed to use other human beings to help. When you are finished then upload ONE file with all of your

work. You can do this using the app Adobe Scan (free with your burbankusd credentials) or by uploading

images of your work to different pages in a google doc. Make sure that your pictures are clear, legible,

and that there is not a bunch of extra space around the edges of your paper in the picture.

1. Qualitative Data

a. Create a question you can ask 20 people that has an answer that would be considered a

qualitative variable. Write your question down.

b. Ask 20 people the question you came up with in part a and record their responses. If you

cannot ask 20 people, make up reasonable answers and CLEARLY label you made up the

responses (you can still get full credit). You can label the ones you made up either by

highlighting or making a separate column, see the example below.

c. Represent the data using a Pareto Chart and a Pie Chart. Include the calculations to find

the angle measures and the percentages for the Pie Chart.

2. Quantitative Data

a. Ask 19 students and yourself, “At what age would you first consider someone to be old?”.

Write the responses below. If you cannot ask 19 students, make up reasonable answers and

CLEARLY label you made up the responses (you can still get full credit). Label them the

same way you did in question 1.

b. Represent the data using a frequency Table, use a minimum of 5 classes.

c. Use your frequency table to construct a histogram and a frequency polygon for the age

data. Make sure you show or explain how you determined the class width and what value

you started the first class with.

d. Calculate the mean, median, mode, range, and standard deviation of your data. Show your

work and all of the steps for each of these. You can organize it into a table just like we did

in the notes and independent work.

3. Quantitative Data Part 2

a. Create a question you can ask 20 people that has an answer that would be considered a

quantitative variable. Write your question down.
