Using Excel Questions
In completing these questions be sure to refer to both the graphing information included
with the syllabus and the Using Excel reference. Don’t forget to include titles and labels
with appropriate units on all charts and graphs.
1. Using data set 1 graph heart rate(Y) vs VO2(X). (When a graph is named as
variable 1 vs variable 2 this means that variable 1 is the dependent or vertical (y)
axis variable and variable 2 is the independent or horizontal (x) axis variable).
Include a best fit line and show r2 and the equation to the line on the graph.
Include the completed graph as the answer. (3pts)
2. Using data set 2 for this question. Placing the new values in column D, convert
the units of VO2 from dL/min to L/min (1 dL = 1/10 L) for each %incline. Next
divide Ve L/min (column B) by VO2 L/min (should now be in column D) for
each %incline. Place these values in column E. Reduce the number of decimal
places in column E by:
highlighting the values
right clicking
selecting format cells
selecting number from the new menu
changing the number of decimal places to 2.
Making sure that all columns are appropriately labeled, include the completed
table as your answer to this question. (3pts)
3. Continuing using data set 2, graph Ve and VO2 (L/min) vs %incline (workload).
Use an XY scatter plot with two y-axis (for Ve and VO2) labeled appropriately
and the x-axis labeled %incline (see the handout to help procedure). Make sure to
label the data series for Ve and VO2 in the legend and to include the proper units
in this label. Also make sure that the data series are easily distinguishable by
changing the Ve data series to crosses (or triangles) instead of dots (found under
format data series by right clicking on a point in the series). Include the
completed graph as the answer. (3pts)
4. Using the values for Ve/VO2 that you just calculated, make a graph of Ve/VO2 vs
%incline. Change the vertical axis scale to have a minimum value of 1.6. Change
the background color of the graph to clear (right click on the graph inside the axis
and select clear). Include the completed graph as the answer. (3pts)
5. Using data set 3 graph # of pedal revolutions vs. time on a x,y scatter using a
smoothed line. Be sure to include the data points on the graph. Remove the
legend (found in chart options by right clicking on the graph). Include the
completed graph as the answer. (3pts)
