MATH221 Statistics for Decision Making
Week 2 Lab
Name: _______________________
Statistical Concepts that you will learn after completing this iLab:
• Using Excel for Statistics
• Graphics
• Descriptive Statistics
• Empirical Rule
Week 2 Lab Instructions-BEGIN
? Data have already been formatted and entered into an Excel worksheet.
? Obtain the data file for this lab from your instructor.
? Use the Week 1 spreadsheet (available from the top of the Week 1 Lesson) for graphs
and calculations. You will need to copy data from the data file into the calculations
spreadsheet to answer some questions.
? The names of each variable from the survey are in the first row of the Worksheet.
This row has a background color of gray to identify it as the variable names. All other
rows of the Worksheet represent a certain students’ answers to the survey questions.
Therefore, the rows are called observations and the columns are called variables. On
page 6 of this lab, you will find a code sheet that identifies the correspondence
between the variable names and the survey questions.
? Follow the directions below and then paste the graphs from Excel in the grey areas
for question 1 through 3. You will be using the Week 1 Excel Sheet for many of the
calculations. Type your answers to questions 4 through 11 where noted in the grey
areas. When asked for explanations, please give thorough, multi-sentence or
paragraph length explanations.
? The completed Lab Word Document with your responses to the 11 questions will be
the ONE and only document submitted to the Week 2: Lab. When saving and
submitting the document, you are required to use the following format: Last Name_
First Name_Week2Lab.
Week 2 Lab Instructions-END

Creating Graphs
1. Create a pie chart for the variable Car Color: Select the column with the Car variable,
including the title of Car Color. Click on Insert, and then Recommended Charts. It
should show a clustered column and click OK. Once the chart is shown, right click
on the chart (main area) and select Change Chart Type. Select Pie and OK. Click
on the pie slices, right click Add Data Labels, and select Add Data Callouts. Add
an appropriate title. Copy and paste the chart here.
2. Create a scatter plot with the variables of Drive and Money. Copy the Drive variable
from the data file and paste it into the x column in the Scatter Plot worksheet of the
Week 1 Excel file. Copy the Money variable from the data file and paste it into the y
column. Copy and paste the scatter plot below.
3. Create a histogram for the variable Drive. You need to create a frequency distribution
for the data by hand. Use 5 classes, find the class width, and then create the classes.
Once you have the classes, count how many data points fall within each class. It may
be helpful to sort the data based on the Drive variable first. Once you have the
classes and the frequency counts, put those data into the table in the Freq Distribution
worksheet of the Week 1 Excel file. Copy and paste the graph here.
Calculating Descriptive Statistics
4. Calculate descriptive statistics for the variable Sleep by Gender. Sort the data by
gender by clicking on Data and then Sort. Copy the Sleep of the males from the data
file into the Descriptive Statistics worksheet of the Week 1 Excel file. Type the mean
and standard deviation below. These are sample data. Then, copy and paste the
female data into the Descriptive Statistics workbook and do the same. Keep three
decimal places.
Mean
Females
Males
Standard deviation

Short Answer Writing Assignment
All answers should be complete sentences.
5. What is the most common color of car for students who participated in this survey?
Explain how you arrived at your answer.
6. What is seen in the scatter plot for the Drive and Money variables? Explain your
answer.
7. What is seen in the histogram created for the driving distance of students in this class
(include the shape)? Explain your answer.
8. Compare the mean hours of sleep for males and the mean for females in these data.
Compare the values and explain what can be concluded based on the numbers.
9. Compare the standard deviation for the sleep of males and the standard deviation for
the sleep of females in the class. Compare the values and explain what can be concluded
based on the numbers.
10. Using the empirical rule, 95% of female sleep amounts should be between what two
values? Either show work or explain how your answer was calculated.
11. Using the empirical rule, 68% of male sleep amounts should be between what two
values? Either show work or explain how your answer was calculated.
