## Project Description:

You are a teaching assistant for Dr. Elizabeth Croghan’s BUS 101 Introduction to Business class. You have maintained her gradebook all semester, entering three test scores for each student and calculating the final average. You created a section called Final Grade Distribution that contains calculations to identify the number of students who earned an A, B, C, D, or F. Dr. Croghan wants you to create a chart that shows the percentage of students who earn each letter grade. Therefore, you decide to create and format a pie chart. You will also create a bar chart to show a sample of the students’ test scores. Furthermore, Dr. Croghan wants to see if a correlation exists between attendance and students’ final grades; therefore, you will create a scatter chart depicting each student’s percentage of attendance with his or her respective final grade average.

A pie chart is an effective way   to visually illustrate the percentage of the class that earned A, B, C, D,   and F grades.
Use the Insert tab to create a pie chart from the Final Grade Distribution   data located below the student data in the range F35:G39 and move the pie   chart to its own sheet named Final Grade Distribution.

You should enter a chart title   to describe the purpose of the chart. You will customize the pie chart to   focus on particular slices.
•Apply the Style 12 chart style.
•Type BUS   101 Final Grades: Fall 2021 for the chart title.
•Explode the A grade slice by 7%.
•Change the F grade slice to Dark Red.
•Remove the legend.

A best practice is to add Alt   Text for accessibility compliance.
Add Alt Text: The pie chart shows percentage of students who earned   each letter grade. Most students earned B and C grades. (including the period).

You want to add data labels to   indicate the category and percentage of the class that earned each letter   grade
Add centered data labels. Select data label options to display Percentage and   Category Name in the Inside End position. Remove the Values data labels.

Apply 20-pt size and apply   Black, Text 1 font color to the data labels.

You want to create a bar chart   to depict grades for a sample of the students in the class.
Create a clustered bar chart using the ranges A5:D5 and A18:D23 in the Grades   worksheet. Move the bar chart to its own sheet named Sample   Student Scores

Customize the bar chart with   these specifications: Style 5 chart style, legend on the right side in 11 pt   font size, and Light Gradient – Accent 2 fill color for the plot area.

Type Sample Student Test Scores for the chart title.

Displaying the exact scores   would help clarify the data in the chart.
Add data labels in the Outside End position for all data series. Format the   Final Exam data series with Blue-Gray, Text 2 fill color.

Select the category axis and   display the categories in reverse order in the Format Axis task pane so that O’Hair is listed at the top and Sager is listed at the bottom of the   bar chart.
Add Alt Text: The chart shows test scores for six students in the   middle of the list. (including   the period).

You want to create a scatter   chart to see if the combination of attendance and final averages are related.
Display the Grades worksheet. Select the range E5:F31 and create a scatter   chart. Cut the chart and paste it in cell A42. Set a height of 5.5″ and a width of 5.96″.

Add Alt Text: The scatter   chart shows the relationship of each student’s final grade and his or her   attendance record. (including   the period).

Titles will help people   understand what is being plotted in the horizontal and vertical axes, as well   as the overall chart purpose.
Make sure the scatter chart is selected. Type Final Average-Attendance Relationship as the chart title, type Percentage of   Attendance as   the primary horizontal axis title, and type Student Final Averages as the primary vertical axis   title.

To distinguish the points   better, you can start the plotting at 40 rather than 0.
Make sure the scatter chart is selected. Apply these settings to the vertical   axis of the scatter chart: 40 minimum bound, 100 maximum bound, 10 major units, and a number format with zero decimal places.

Make sure the scatter chart is   selected. Apply these settings to the horizontal axis: 40 minimum bound, 100 maximum bound, automatic units.

Adding a fill to the plot area   will add a touch of color to the chart.
Make sure the scatter chart is selected. Add the Parchment texture fill to   the plot area.

You want to insert a trendline   to determine trends.
Make sure the scatter chart is selected and insert a linear trendline.

You want to add sparklines to   detect trends for each student.
Select the range B6:D31 on the Grades sheet, create a column Sparkline, and   type H6:H31 in the Location Range box.   Display the Low Point. Set the Vertical Axis Minimum and Maximum Values to be   the same for all Sparklines.

To make the Sparklines more effective   and easier to read, you will increase the row height.
Change the row height to 22 for rows 6 through 31.

Insert a footer with Exploring   Series on the   left, the sheet name code in the center, and the file name code on the right   on all the sheets. Group the two chart sheets together to insert the footer.   Then insert the footer on the Grades sheet. Change to Normal view
