In order to ensure that appropriate advice be given, the consulting is strongly suggested at the design stage of the experiment. The following information from researcher is very helpful: * A complete and concise summary of information about the experiment, * Experimental units, i.e., animal strain/Humans, etc. How were they selected? * Sample preparation procedure if any * Was the experiment conducted on different days/times, etc? * Clear and concise research questions to be investigated * Specify the number of experimental conditions (factors) that you plan to study, that might influence the response variable (gene expression values in case of microarray experiments) * Number of stages that the experiment will be conducted. This will help us make sure that any factor (condition) of interest is not confounded with some non-biological factor, etc. * The type of analysis that the researcher would think would be suitable to perform * The type of chip that would be used, if microarray experiment * Number of the samples that researcher is planning based on budget It would take a week to make a framework for the issues and suggest the statistical feasibility for the project. The statistician would give recommendations for the number of samples, any other design issues, randomization, blocking etc.
