In: Statistics and Probability
For the following data sets, are the samples positively skewed, negatively skewed or approximately symmetric? (You can use R to justify your answer.) (a) A = {0.9961905,0.9493184,0.8332006,0.9513567,0.9856061,0.9136707,0.9706223, 0.6834221, 0.8527071, 0.8052218, 0.9798628, 0.9862662}. (b) B = {0.256907054,0.371948965,0.302661234,0.245459145,0.488603820,0.435416721, 0.203228122, 0.004436282, 0.115262446, 0.058988085, 0.256066243, 0.141507075}.

EXPLANATION ::-
R codes and output.
a)
>
A<-c(0.9961905,0.9493184,0.8332006,0.9513567,0.9856061,0.9136707,0.9706223,0.6834221,0.8527071,0.8052218,0.9798628,0.9862662)
> boxplot(A)
By using Boxplot we say that data is negatively skewed.
b)
>B<-c(0.256907054,0.311948965,0.302661234,0.245459145,0.488603820,0.435416721,0.203228122,0.004436282,0.115262446,0.058988085,0.256066243,0.141507075)
> boxplot(B)
By using Boxplot we say that data is negatively skewed.
c)

C<-c(0.139061819,0.025883617,0.096332657,0.115620817,0.274004925,0.059080122,0.072580116,0.008576388,0.068673036,0.379232748,0.117313230,0.086692960)
