“... the actual goal of public speaking is to connect with your audience, not to overwhelm or impress them with your depth of knowledge and imperial bearing.” Montgomery, 2003, p. 180

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

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

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.

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

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.

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

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

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

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

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

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

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

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 = 0.0595)

Results

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.

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.

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!

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

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!!!

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

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!

Checklist for Oral Report Creation Create a story to tell Create a clear outline of the talk Keep slides simple Make pretty graphs and tables Use simple phrases Assume one slide will take 1-2 minutes. Clear overall result No typos/consistent format

Oral Reports: Preparation The next lecture will transition from finished slides to a successful talk.
