    In solutions for chapter 10 practice questions, Q10.10(iii) , under ISD test, it's given that the distribution is positively skewed, which is not so good.
    How did we come to a conclusion that it is positively skewed?
    Also while we talk about symmetry, we tend to look at the number of positive and negative deviations which are 5 and 4 respectively in this case, so from this can't we conclude that it is fairly symmetrical?
