For each of the following, determine whether the distribution described is more likely skewed right, skewed left, or relatively symmetric.

Number of sick days in the GC student population
Salaries for all players in the NFL
Number of cars owned per American citizen
Heights of all females in the GC population

Solutions

Expert Solution

a-Here the data is more likely to be Positive skewed as lower number of absents or sick days will have larger probability. So it is more skewed to the right.

b-Here the data can be symmetric. Some players like freshers will have less salary, majority of players will have salary in mid range and again few players will have high salary depending on experience.

c-This will be Positive skewed as number of cars owned will highly take values 0,1,2 per citizen.. Any value above this will be rare. So this is positive skewed.

d-Heights will be Symmetric as most of the height of females will lie around 5-5.5.Any height below or above this range will be rare. So it might be symmetric
