##'''Expectations from Statistical Consulting/Analysis of Microarray Experiments '''
##'''Cancer Stem Cell Network'''

'''Office hours''' : '''Tuesday 3:00pm-5:00pm''' and '''Thursday 11:00am -1:00pm'''

Statistical consulting for experiments in the Cancer Stem Cell Program is available by contacting Biostatistician Changjiang Xu at changjiang.xu@utoronto.ca. In order to ensure that appropriate advice be given, the consulting is strongly suggested at the design stage of the experiment.

Upfront required Information from researcher

·         Please provide '''a complete and concise summary of''' information about the experiment,

·         Experimental units i.e., animal strain/Humans, etc. How they were selected?

·         Sample preparation procedure if any?

·         If experiment conducted on different days/times etc?

·         Clear and concise '''research question'''s that you want to investigate

·         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

·         What type of chip would be used, if microarray experiment?

·         How many samples that researcher is planning  based on budget

After this upfront meeting, the statistician would take '''a week'''  to make a framework for the issues and suggest the statistical  feasibility for the project etc. The statistician would give  recommendations for the number of samples, any other design issues,  randomization, blocking etc.
