Montgomery, 2003, p. 180

3. Oral Reports
In this class, you will be expected to give a 10 minute oral presentation to the entire class.
In this lecture, I will outline:
How to create an oral report
What to do for your oral report

4. Creating an Oral Report
According to Brenda Sims, there are four types of oral presentations:
Impromptu
Extemporaneous
Scripted
Memorized
(Sims, 2003, p. 533)

5. Creating an Oral Report
While scripted has its place,
Lots of precise information
Most people prefer the extemporaneous report the most:
Organized
Prepared
Conversational
Allows for adjustment in response to audience’s reaction.

6. Creating an Oral Report
How to create a planned presentation:
Organizing the report:
Plan the report
Make slides
Appearance
Number
Meet with team and restructure
Practicing the report

7. Creating an Oral Report: planning the report
General recommendations:
Create a narrative
Organize into an outline
Make a couple of levels of divisions
Condense presentation into a few key points. Do not try to give every bit of information on the topic.

8. Creating an Oral Report: planning the report
Think about how to best illustrate each idea:
Words
Graphics
Stay within your allotted time (??)
Plan the presentation to take slightly less than the allotted time.
Look for ways to tighten your presentation

9. Creating an Oral Report: making slides
Your slides need to be simple (Montgomery, 2003, p 177)
Choose a background that doesn't overwhelm
Present concepts as phrases
Keep fonts large and sans serif
One idea per slide
Just enough information to guide you and focus the audience

10. Creating an Oral Report: making slides
How many slides should you make?
It takes longer to comprehend spoken information than written information (Sims, 2003, p. 535)
Preview structure of talk in early slides
Allow 1 to 2 minutes per slide
Allow time at the end for questions

11. Creating an Oral Report for Stat 4893W
For your presentation:
We are your audience!
You have 10 minutes
Prepare 6 – 8 slides (plus title)
Use PowerPoint

12. Does the source of protein and amount of protein affect weight gain in mice?
Marta Shore
Stat 4893W

13. Background
Researchers wanted to see if weight gain in mice was affected by:
The source of protein: beef, cereal, or pork
The amount of protein: high or low

14. Results Table A. Summary statistics for the 6 protein groups
Protein Type
Mean
Standard Deviation
beef, low protein
79.2 grams
13.9 grams
beef, high protein
101.0 grams
14.0 grams
cereal, low protein
83.9 grams
15.7 grams
cereal, high protein
85.9 grams
15.0 grams
pork, low protein
78.7 grams
16.5 grams
pork, high protein
99.5 grams
10.9 grams

15. Results
no significant difference in weight gain for the different sources of protein
significantly more weight gain for the mice receiving high levels of protein (p=0.0002)
possible interaction between the source and the level of protein (p = )

16. Results

17. Conclusions The protein source doesn't affect weight gain.
More protein from beef and pork results in more weight gain.
More protein from cereal does not affect weight gain.

18. The oral report requirements for Stat 4893W
In this class, you will need to present a 10 minute report about the Island consulting project. The goal of the report is two-fold:
Work with two other people on your team to come to a consensus about the topic.
Present the consensus clearly and within the time allowed.
The details will be outlined for each type of presentation.

19. Creating an Oral Report about the Study Design
Step 1: Meeting with your team
Get reports from everyone on your team
Talk about what each person did
Make sure each team member is heard and that you understand what was done to create the study design.

20. Creating an Oral Report about the Study Design
Step 2: Writing the report
Outline the study design
Discuss the clinical aspects of the design
Discuss the statistical aspects of the design
Examples of statistical ideas to discuss
How did you randomly sample Islanders for the study?

21. Creating an Oral Report about the Study Design
Step 2: Writing the report
Examples of statistical ideas to discuss
How did you estimate the sample size?
Discuss why the stratified randomization was necessary and how it was performed
What analysis do plan to do?
Summarize the overall goals of the presentation
And always write for your audience!

22. Creating an Oral Report for the Data Analysis Project
Step 1: Meeting with your team
Get reports from everyone on your team
Talk about what each person did
Why did s/he do that analysis?
What conclusions were made?
Decide what the best approach is:
Which tests make the most sense
Which graphics to use
Make sure each team member is heard and agrees to the final approach

23. Creating an Oral Report for the Data Analysis Project
Step 2: Writing the report
Summarize the goal of the research
Show the overall trends
Can use graphs or tables
Make sure the trends illustrate the goal
Summarize the statistical inference
Hypothesis test and additional information
Results – major takeaway message
Any concerns?
And always write for your audience!
Do NOT show R code or Excel spreadsheets!!!

24. Creating an Oral Report about the Consulting Experience
Step 1: Meeting with your team
Get reports from everyone on your team
Talk about what each person did
Make sure each team member is heard and that you understand what was done to create the study design

25. Creating an Oral Report about the Consulting Experience
Step 2: Writing the report
Outline what went well and why with your team?
Outline what needed to improve and suggest improvements?
Outline what you and your team learned about communicating during consulting
Provide examples of communicating statistical concepts to non-statisticians.
Summarize the overall accomplishments.
And always write for your audience!
