Interpreting Linear Regression Coefficients: A Walk through Output

September 26th, 2011 by

In this webinar we’re doing something a little different – rather than give you an overivew of a topic, we will interpret together the regression coefficients table from a real data set.

This data set is from the dissertation of a client I worked with a few years ago.  She has graciously allowed us to use her data as an example.  It’s a great example because it includes many of the coefficients that can be really tricky

Binary, Ordinal, and Multinomial Logistic Regression for Categorical Outcomes

Ever discover that your data are not normally distributed, no matter what transformation you try? It may be that they follow another distribution altogether. During this teleseminar, Karen Grace-Martin explained

The First Three Steps to Performing Any Statistical Model: Define and Design Webinar

September 29th, 2009 by

The next webinar in the Craft of Statistical Analysis series is:

The First Three Steps to Performing Any Statistical Model: Define and Design

All statistical modeling–whether ANOVA, Multiple Regression, Poisson Regression, Multilevel Model–is about understanding the relationship between independent and dependent variables. The first 3 steps in modeling set up the entire rest of the analysis.

This webinar will go into more detail on these first three steps:

1. Write out research questions in theoretical and operational terms

2. Design the study or define the design

3. Choose the variables for answering research questions and determine their level of measurement

It is the way you do these three steps that determines the rest of the analysis. Doing them explicitly and doing them well can save you days of time and endless frustration.

This webinar has already taken place, but the recording of it is available in our Statistically Speaking membership program.
