Sr. Statistical Consultant

The Problem:

In order to compare the effects of several factors on some phenomena, it is common to conduct an experiment.  For example an oil company wants to study how three different gasoline types affect the mileage obtained by a popular automobile mode. In this case the oil company will need to collect mileage data from a representative sample of cars. 

A supplier of a bakery product to supermarkets may want to study the effect of the shelf display height on monthly sales. In this case, the supplier will need to collect sales data from a representative sample of supermarkets.

In either situation, there are key questions to be asked:

• What statistical method should be used to analyze experimental data?

• What difference in the factor effects should be considered meaningful?

• How should the sample units be assigned to the various treatments?

• How many sample subjects should be part of the experiment?

• Are they any other factors that could potentially affect the outcome?

What I can do:

• As a professional statistician, with years of experience in study design and statistical analysis, I can help you streamline your research goals, and choose the most appropriate statistical technique.  

• I can assist you with the interpretation of the results, as well as with the writing of the technical sections of your research report.

• I can perform power analysis for you to determine the sample size necessary to give your analysis the power you need.  If necessary, I will find the right balance between the power requirements and cost considerations.

• I am an excellent programmer, and can assist you with the programming required to manipulate your datasets for the purpose of analysis.
