Writing a formula

BMI = BODY MASS INDEX

= WEIGHT (kg) / height2 (m) e.g., 5 ft 4 inch & 145 lbs

= 64 inches, 145 lbs

= 1.62 meters, 66 kg

= 66 / 1.62562 BMI = 25

Note that in Excel, the multiplication sign * must be included when needed, Excel does not multiply round brackets

Copying excel material to word

For writing a report: You will produce a professional report by copying the graph and pasting it into a Word document to create on Word file with text and figures. To copy the graph to word: Select the graph. Ensure you select the whole graph, i.e., click near the edge of the graph frame and see the outer most edge of the graph indicated by the

selection box. Do not select only the axis portion of the graph by clicking at the center of the graph. Copy the graph. Then open your word report document, and place the cursor where you want the graph to go, and paste the graph in.

To copy the output table to word: Select the range of cells you wish to copy. Copy the range. Then open your word report document, and place the cursor where you want the table to go, and paste the data table in.

Backup your work

Ensure you have more than one copy of any work you care about!!!

The following are advanced techniques required of KIN 506 students, and potentially useful for KIN 306 students when writing lab reports.

Advanced bar graph techniques

To plot mean and standard deviation values for groups to report results.

We will use the following data to produce the following sample graph:

Mean Aerobic Capacity (ml/kg/min) Pre-training Post-training

males 45 50

females 30 40

Standard Deviation of Aerobic Capacity (ml/kg/min)

Pre-training Post-training

males 10 15

females 2.5 5

Mean Aerobic Capacity of Males & Females

0 10 20 30 40 50 60 70

males females

Maximum Aerobic Capacity (ml/kg/min)

Pre-training Post-training

*

graph the means of variability of groups

Insert tab: charts: column: select top left sub-type (plain column graph):

Chart must be selected or chart tools will not be available

Chart tools: Design: Data: Select data:

Select data source:

Remove any contents if present click on Add button

select series name box, click on cell that contains name of data set (e.g. "Pre- training"). This is the term that will appear in the figure legend.

select (drag over) the column of cells containing the bin labels (i.e. males &

females) OK

to add the second data series, click on add AGAIN click in Name box to place cursor there

select a cell containing the label of the data second set of data (e.g. "Post- training"). This is the term that will appear in the figure legend highlight the Values box to select it

select (drag over) the column of cells containing the second data (e.g., post- training data for males & females, do not include column titles).

OK

Control legend (Keep legend if you have more than one set of data on one axis pair) Chart tools: Layout: legend: position/none

turn off Value (Y) axis Major Gridlines (not needed in this simple plot, may be needed in more complex ones you make)

Chart tools: Layout: axis: gridline: Horizontal gridlines

enter appropriate title, and labels for both value (X) axis, & value (Y) axis Chart tools: Layout: Labels: Chart title

Chart tools: Layout: Labels: Axis title

NOW CHECK THE PLOT AGAINST THE DATA!!

Double click on any item in the graph you wish to modify (experiment!) Optional - to set a fixed range on an axis:

RIGHT Click on the axis line or tick label to open operation box

Use options in box to set reasonable (& not conflicting) min, max, step sizes, # decimals displayed etc.

Now add the error bars to first data set:

Chart tools: Layout: analysis: error bars: more error bar options:

Select ONE set of data. (e.g., Pre training) OK

Select "Both" & "Custom"

“specfy value”

Place cursor in "+" range box

Drag and select the column of male & female pretraining standard deviation values

Place cursor in "-" range box

Drag and select the column of male & female pretraining standard deviation values

(8)

OK

Now add the error bars to second data set - by repeating the above procedure for the second data set

Note:

 You can insert text (such as a symbol to mark significance) by using: Insert: text:

text box.

 You can change the words used in the graph legend by changing the text of the corresponding cell in the excel spreadsheet.

 Changes in the data in the excel spreadsheet will automatically be replotted.

 The same data can be plotted in an alternative organization, as shown below, by:

Chart tools: design: data: Switch row/column

Mean Aerobic Capacity Pre and Post Training for Both Sexes

0 10 20 30 40 50 60 70

Pre-training Post-training Maximum Aerobic Capacity (ml/kg/min)

males females

Non-parametric test – Chi Squared Chi Squared analysis

See sample data in Excel lesson data worksheet.

Organize table of Actual Observations

Calculate table of Expected Observations (using absolute and relative addresses) Expected responses = (column total x row total) / N

Use function: CHITEST (use function help if needed) Function returns probability

Note that you can copy the first Chi Squared test you build, and use it as a template for additional questions.
