Are these data skewed to the left (negatively skewed) or skewed to the right (positively skewed)? 1, 2, 2, 2, 2, 3, 3, 3, 3, 4, 4, 4, 9, 1850

Expert Solution

OR By using R command

X=c(1, 2, 2, 2, 2, 3, 3, 3, 3, 4, 4, 4, 9, 1850)
M=mean(X)
Med=median(X)
Sk=sum((X-M)^3)/((length(X)-1)*sd(X)^3)
Sk
[1] 3.207053
# Here Sk>0 therefore data is skewed to right(Positively skewed)
a=3*(M-Med)/sd(X) # karlpearson measure of skewness
a
[1] 0.8031805
# Here a>0 therefore data is skewed to right(Positively skewed)

Example of a situation where a data set might be negatively skewed. Do the same for a positively skewed distribution.

Example of a situation where a data set might be negatively skewed. Do the same for a positively skewed distribution. As this is a discussion, check the other answers first to make sure your answer isn't already taken. If necessary, explain why the skews might be the way they are.

Imagine that we have a population that is positively (right) skewed that has a mean of 114 and a standard deviation of 12. Using a computer simulation program, Jake creates a sampling distribution of size n=5 from this population and Alex creates a sampling distribution of size n=40 from this population. How would Alex’ and Jake’s sampling distributions compare to each other? Group of answer choices They would have the same mean and shape, but would differ in standard error....
