Chocolate Cake Seminar Series an Statistical Applications

 
Can you find two mistakes in this sentence?... "I don’t know much about statistics, but I’ve collected this data. How do I analyze it?”
If you can't, you're not alone.  
Bring your lunch to the Chocolate Cake Seminar Series on Statistical Applications and get some answers. (The Chocolate Cake is on us!)
Look below for a list of previous and upcoming topics.
__________________________________________________

And what about those mistakes?...
Error #1: Don't let data analysis be an afterthought.  Come and talk about designing your data collection with a plan for analysis in advance.
Error #2: “Data” is plural. So, if you need to learn how to analyze THEM, join us at the seminar series.  Drop in or be a regular. We guarantee you’ll learn some statistics!

 

Apr 15, 2013 Ms. Kelley Mizukami Surviving Survival Analysis

Chocolate Cake Seminar Series on Statistical Applications


Apr 15, 2013
FO 5-Room 116

Let’s pretend you participate in a weight loss study. The study isn’t over yet, but you got a very luring job offer that requires you to move out of state and you cannot continue in this study. Should your data be thrown out and not used for the analysis after all since you never completed the study? The answer is “No, not at all”. The talk will explain how to model times to events (e.g., 20% excess body weight loss) in presence of drop-outs. Two survival analysis techniques, Kaplan-Meier curve and Cox model, will be studied through SAS and SPSS applications.

Have you ever counted how many cars are in front of you at McDonald’s drive-thru? Is it a number between zero and infinity? Well, just notice the hour of the day and you got yourself a Poisson regression. Attend the talk and learn how to model properly the relation between the number of cars and the hour of the day. You won’t be bored. We promise. Applications in SAS and SPSS will definitely keep you awake.

How can you tell how many people you need for your study? Is it ten, twenty, sixty, one hundred?  The number of participants should not be determined by time and budget alone. Statistical rigor, called power analysis, must be applied. The talk will expose the details with applications in SAS and other specialized softwares.

Oct 22, 2012 Ms. Kelley Mizukami What are One-Way and Two-Way Analyses of Variance?

Seminar Series: Statistical Applications


Oct 22, 2012

Have you ever wanted to test if the means of several groups were the same or not? Then analysis of variance (ANOVA) is what you need. This presentation will discuss how to test whether several means are the same in designs with one factor as well as two factors using such statistical software packages as SAS and SPSS. There will be time for questions and discussion at the end.

If you would like to study the association between a continuous outcome variable and several independent variables, a linear regression is your tool. The talk will display how to develop well-fit models using such statistical software packages as SAS and SPSS. There will be time for questions and discussion at the end of the presentation. view

RIMI Brown Bag Seminar Series on Statistical Applications


May 2, 2012

What if the variable you are about to model assumes only a handful of different values? Can you say it is a continuous variable and use a linear regression model?  The answer is enthusiastically, “No!” The talk will explain why it is so and introduce you to appropriate regression approaches. SAS and SPSS statistical software packages will be employed. Basic knowledge of linear regression modeling will be required.  There will be time for questions and discussion after the presentation.
