I have completed master's thesis with an advisor in Industrial Engineering and I am pursuing PhD with another professor in same department. My PhD involves statistics heavily and I am not at all good with statistics. In fact I have C in two mandatory statistics courses I took in the masters program.
Usually this lab works with a Chinese statistics professor. I find it very difficult to understand her. I find her to be very knowledgeable but are just not good at explaining things. Would it be acceptable if I asked my advisor to bring my master's advisor on board the PhD committee so that she can help me with the statistics material? He taught entry level statistics courses in masters program and helped me substantially with the statistics material of my master's thesis.
Will I have any leeway to do something like this especially when he is funding me for PhD, and what will be the best way to bring this up?
