Please have your instructor or TA initial each level as you
complete it. If you need additional help, ask the TAs or use the
help guide within Excel.
Once you master Excel Levels I through IV, you can note Excel
as a skill on your resume!
Please see D2L Content for this week for your Excel Homework

Level I: Basic Functions Initials
_______
1. Calculating an Average: Calculate the arithmetic average
of the 5 values listed below. Enter the values in cells A2
through A6. Place a descriptive label in cell A1.
3.6, 3.8, 3.5, 3.7, 3.6
First, calculate the average the long way, by summing the
values and dividing by 5:
You will enter the following formula into a blank cell to
accomplish this:
=(A2+A3+A4+A5+A6)/5
Second, calculate the average using Excel’s AVERAGE( )
function by entering the following formula in a cell:
=AVERAGE(cellrange)
Replace the “cellrange” with the actual addresses in your
spreadsheet of the range of cells holding the five values (i.e.,
for this problem, the cell range is A2:A6).
2. Determining Velocities (in kph): Some friends at the
University of Calgary are coming south for spring break. Help
them avoid a speeding ticket by completing a velocity
conversion worksheet that calculates the conversion from mph

2. to kph in increments of 10 from 10 to 100. A conversion factor
you will need is 0.62 miles/km; you will need this factor to
convert from miles/hour to km/hour. Place the conversion factor
in its own cell and then reference it in your conversion
calculations using absolute cell referencing (e.g., $C$2). Refer
to the CBT video on Absolute and Relative Cell Referencing
from the “Preparation for the Excel Workshop” assignment if
you don’t remember how to do this.
Level II: Advanced Functions Initials
_______
1. Projectile Motion I: (See following page for Fig. 1 Excel
chart) A projectile is launched at the angle 35o from the
horizontal with a velocity equal to 30 m/s. Neglecting air
resistance and assuming a horizontal surface, determine how far
away from the launch site the projectile will land.
To answer this problem, you will need:
1. Excel’s trigonometry functions to handle the 35o angle, and
2. Equations relating distance to velocity and acceleration
When velocity is constant, as in the horizontal motion of our
particle (since we’re neglecting air resistance), the distance
traveled is simply the initial horizontal velocity times the time
of flight:
(Equation 1)
What keeps the projectile from flying forever is gravity. Since
the gravitational acceleration is constant, the vertical distance
traveled becomes
(Equation 2)
Because the projectile ends up back on the ground, the final
value of y is zero (a horizontal surface was specified), so
Equation 2 can be used to determine the time of flight, t:
t = 2(voy)/g, where g = 9.8 m/s2 (Equation 3)
The initial velocity components in the horizontal and vertical
directions can be determined with Excel’s trigonometry
functions, as shown in Figure 1 (following page).

3. In Figure 1, Cells C6 and C7 must contain the following
formulas:
Cell C6: =C4*SIN(RADIANS(C3))
Cell C7: =C4*COS(RADIANS(C3))
The RADIANS( ) function has been used to convert 35o to
radians for compatibility with Excel’s trigonometric functions.
Once your spreadsheet has calculated V0y and V0x, you can use
Equation 3 to solve for the time of flight in Figure 1. The time
of flight can then be used in Equation 1 to find the horizontal
distance traveled.

Checking your answers:
Given the information above, your spreadsheet should calculate

6. that for V0 = 30 m/s and the launch angle = 35 degrees, V0y =
17.21 m/s and V0x = 24.57 m/s. In addition, your spreadsheet
should calculate that t = 3.51 s and x = 86.30 m.
If your spreadsheet is not giving you these results, your
formulas are likely incorrect, so keep working.
2. Projectile Motion II: How do the flight time and horizontal
distance traveled change if the launch angle is decreased to 30
degrees (launch speed is unchanged)?
Level III: Using Excel for Statistics
Initials _______
1. Statistics: Sixty transducers are tested to see how long
they work without failure in a given environment. Rather than
typing in the data, use Excel’s random number generator to
generate 60 data points between 0 and 3 (one way to do this is
to type “=RAND()*3”).
You may notice that the sixty randomly-generated values
change each time you make changes to other areas of your
worksheet. You should “freeze” these values by copying them
and then using “Paste Options: Values” to paste the random
number values into an adjacent column.
Use Excel’s statistical functions—AVERAGE, MEDIAN, MAX,
MIN, STDEV.S, and QUARTILE.INC—to calculate statistics
for your “frozen” data (calculate the 1st, 2nd, and 3rd quartiles;
check to see whether your calculated 2nd Quartile = median).
2. Statistics, continued: For the data you generated in (1.)
above, generate a histogram, which is a type of graph that
shows the relative frequency of occurrences:
Decrease the number of decimal places for your data to two.
Use the “Number” tab on Excel’s ribbon to accomplish this.
Determine a suitable X-axis range for the histogram. In general,

7. you could find the range for your X-axis by subtracting the MIN
value from the MAX value. In this particular case, you know
your data ranges from 0 to 3, so use this as your range.
Determine the number of “bins” – recall that a good rule of
thumb is that the number of bins should roughly equal the
square root of n. What is the value of n in this case? Now take
the square root of n and round it to the nearest odd number.
Divide the range by the number of bins to determine the size of
each bin. Since you now know the range and the number and
size of the bins, you can set up a table from which your
histogram can be constructed. Your table will have two
columns: ‘Bin” and “Number of Occurrences.” The value in the
“Bin” column will be equal to the high value of each bin range.
Populate this table using an analysis of your sixty values. You
may want to sort your sixty random numbers from low to high
in order to make this step easier (Editing => Sort & Filter).
Now use Excel to construct your histogram chart. One way to do
this is to highlight your table’s number of occurrences data and
go to Insert => Column => 2-D Column. Then use the bin data
to adjust your X-axis values. To accomplish this, first click on
the X-axis values to highlight them, then go to Chart Tools =>
Design => Select Data. Click on “Edit” under Horizontal
(Category) Axis Labels, then fill in the range where your bin
values are located under the “Add Label Range” field. Now
click “OK.” Click “OK” again in the Select Data Source
window. The Y-axis values should already depict the frequency
of occurrence for each of the bins.
Be sure to remove the space between the columns to create a
proper histogram. To do this, select the data series in the plot:
right-click on one of the columns, then => Format Data Series
=> Series Options => Gap Width => 0%.
Label the axes appropriately and title your graph.

(A) Create a scatter plot of the data (Insert/Charts/Scatter).
Label the axes and give your graph a title (click on chart; Chart
Tools/Design/Chart Layouts/Quick Layout).
(B) Add a trendline and display R2 (a measure of the “goodness
of fit”) (Chart Tools/Layout/Analysis/Trendline). To add a
trendline, you can also right click on the data points and go to
“Add trendline.” See if you can choose a type of trendline that
gives you an R2 very close to 1.0, which means that your
trendline formula is a good fit for your data points.
2. Advanced Graphing: The surface plot in Figure 2 shows the
value of F(X,Y) = sin(X) * cos(Y) for -1 X 2 and -1 Y 2. You
will be reproducing this surface plot.
(Figure 2)
(A) Create the table for F(X,Y) = sin (X) cos (Y) for the ranges
-1 ≤ X ≤ 2 and -1 ≤ Y ≤ 2. Remember to use the $ sign where
appropriate in your formulas for absolute cell addressing.
To create the table, X values ranging from -1 to 2 should be
entered in column A with increments of .2, and Y values
ranging from -1 to 2 should be entered in row 2, also with
increments of .2. The first two values are entered by hand, and
then Excel’s Fill Handle (small square that appears in the
bottom right corner of the selected cells) can be used to
complete the rest of each series. See Figure 3 for illustration of
the first part of the chart (note: the whole chart is not displayed

11. below – you will need to create it within your spreadsheet).

Charts => Surface => “Wire frame” icon).
